For example, if we take 50% of each asset, the expected return and risk of the portfolio will be as follows: E (R) = 0.50 * 12% + 0.50 * 20% = 16% Photo by David Fitzgerald/Web Summit via SportsfilePhoto by David Fitzgerald /Sportsfile. Today, several managers have employed All Weather concepts under a risk parity approach. Risk parity strategies suffered in recent history (2010-2017) as the bull market has pushed stocks to a record high hence favoring equity-concentrated portfolios. It's just now we have all three assets as possibilities in this setting: large stocks, average return, expected average return of eight percent, standard deviation 25 percent, small stocks, average return is almost double, 15 percent, but the standard deviation is much higher, 50 percent. At the tangency point (market point) the slope of the capital market line $L$ and the slope of the efficient frontier (at portfolio $p$) are equal, i.e. xXn6}7TxM6 Z46[c{m]L-b9Dw>lKYd]j2oM` $f8.xp7n _3X!8W.h7 e,4?Q"fQ6HDKUSi~E>Ynt$dd,VB:khYM}j-Ld7ZfY-"4M^$;h}l m The tangency point is the optimal portfolio of risky assets, known as the market portfolio. WebThe Tangency Portfolio is a portfolio that is on the efficient frontier with the highest return minus risk free rate over risk. The tangent portfolio weights are calculated as follows: Summary of capital allocation line Investors use both the efficient frontier and the CAL to achieve different \[\begin{align} Why is that?

If you are using monthly returns this number will need to be adjusted. rate (leveraging) and investing the proceeds in the tangency portfolio L(\mathbf{x},\lambda)=\mathbf{x}^{\prime}\mathbf{\Sigma x+}\lambda\mathbf{(x}^{\prime}\tilde{\mu}-\tilde{\mu}_{p,0}). WebPortfolioOptimizationRecipe Foranarbitrarynumber,N,ofriskyassets: 1.Specify(estimate)thereturncharacteristicsofallsecurities (means,variancesandcovariances). \], \[\begin{equation} The first order conditions for a minimum are: The answer is yes. In other words, the marginal risk contributions for every asset in a risk parity portfolio are equal. \] Either way, real-life trading based on mean-variance principles is not a very successful thing. Portfolio The professor if this is an assignment. I have daily returns of three years. Now we can barely get 1%. I think we already did this before, but review never hurt, and what's a Sharpe ratio for small stocks? We did that in a setting of just large stocks and small stocks. See my "introduction to mathematical portfolio theory", Problem with determining weights in tangency portfolio (2 risky assets), Improving the copy in the close modal and post notices - 2023 edition, New blog post from our CEO Prashanth: Community is the future of AI. However, the increase in market volatility since 2018, the emergency of geo-political and tradewars risk as well as the growth in haven assets like Gold create conditions that strengthen the case for diversified portfolios. Standard Deviation - Standard Deviation of the portfolio with the varying weights of Asset 1 and 2. Standard Deviation of Asset 2 - This can be estimated by calculating the standard deviation of the asset from historical prices. Notes on using Excel to solve Portfolio Theory Questions And how can I know the value for $R_f$ ? How does portfolio allocations maybe improve as a result? Tangency portfolio and the risk-free rate combinations also dominates small stocks for For both numerator and denominator, he also uses excess return, not actual. Expected Rate of Return (Portfolio of Assets) - Expected Rate of Return of the portfolio with the varying weights of Asset 1 and 2. NB: With a risk free rate in the mix, we could add it to our portfolio (and in the efficient frontier its weight is simply fixed at zero,though). You can see the results there. Finally, the course will conclude by connecting investment finance with corporate finance by examining firm valuation techniques such as the use of market multiples and discounted cash flow analysis. Let \(\mathbf{x}\) denote the \(N\times1\) vector of risky What would be the performance of a Ray Dalio FAANG Index i.e.a portfolio composed of FAANG companies and rebalanced to match a corresponding Risk Parity portfolio? Figure 3.6: Portfolio covariance risk budget for parity and tangency FAANG portfolios considering returns from 2018. Embedded hyperlinks in a thesis or research paper. In the case of a long-only restriction, Id assume that asset 1 gets a weight of 0% and asset 2 a weight of 100% - which makes intuitively sense. Ubuntu won't accept my choice of password. It's called the tangency portfolio. Interestingly, in years where the tangency portfolio index had positive cumulative return, the risk parity index yielded less returns than the tangency portfolio index. Copyright 2004-2021 spreadsheetml.com. where \(\mu_{p,t}=\mathbf{t}^{\prime}\mu\) and \(\sigma_{p,t}=(\mathbf{t}^{\prime}\Sigma \mathbf{t})^{{\frac{1}{2}}}\). Now again, the Sharpe ratio we know for the tangency portfolio is the highest Sharpe ratio among all the combinations of risky assets. The Lagrangian for this problem is: It only takes a minute to sign up. A risk parity portfolio seeks to achieve an equal balance between the risk associated with each asset class or portfolio component. Somebody should give it to you. Correlation between large and small here, 0.4 and then Treasury Bills, the risk-free asset mean return of three percent doesn't change, so there's a standard deviation of zero. }\tilde{\mu}_{p,x}=\tilde{\mu}_{p,0}. More Free Templates Here, we're actually going to get a higher Sharpe ratio. Thanks for this, this really helped. Lets get started! We'll assume you're ok with this, but you can opt-out if you wish. \end{align}\] One of the best courses across platforms- classroom or online that I have taken. frontier of T-bills and risky assets consists of portfolios of T-bills \begin{array}{ll}{\mathcal{M}} & {\text { minimize } \quad \frac{1}{2} w^{T} \Sigma w} \\ {\text { subject to }} & {\mathrm{m}^{T} w \geq \mu_{b}, \text { and } \mathbf{1}^{T} w=1}\end{array} This is a fantastic tool for Stewart Calculus sections 2.1 and 2.2. But now the trade-off is small stocks and Treasury Bills, not large stocks, and Treasury Bills. In our example, there are two assets. As presented in Tab. \] Figure 3.8: Portfolio weights for FAANG tangency portfolios. For instance, in the case of $\rho_{1,2}=0,8$ the weight of asset 1 turns out to be 14,29%. If we take an allocation that's 100 percent large stocks, standard deviation of 25 percent, average return of eight percent. and solving for the \(x_{t}\), the weights in the tangency portfolio The fund would be the first in the U.S. to follow this quantitative approach, allotting more money to securities with lower volatility according to Bloomberg.

WebThis is useful for portfolio optimization and portfolio management, as is often covered in qualifications such as the CFA. I see the results but I don't quite understand yet what that actually means. For example, suppose the expected Another way to think about this is, given our assumptions, if you had the choice as an investor, and you could tradeoff between the risk-free rate and a risky asset, you would rather make portfolio trade-offs between the risk-free rate and small stocks, then between the risk-free rate and large stocks. Figure 3.9: Performance summary for the risk parity index versus the tangency portfolio index. A common choice for \(f\), for instance, is the standard deviation of the portfolio, which is usually called volatility, i.e., \(f(\mathbf{w})=\sqrt{\mathbf{w}^{T} \mathbf{\Sigma} \mathbf{w}}\), where \(\mathbf{\Sigma}\) is the covariance matrix of assets. This will produce a portfolio with @stans thank you for your answer. Portfolio For example, here, standard deviation of 25 percent, gives us an expected return of eight percent. Using the first equation (12.31), we can solve for \(\mathbf{x}\) \sigma_{p,x}^{2} & =\mathbf{x}^{\prime}\Sigma \mathbf{x}.\tag{11.5} Stock, Finance, Investment Strategy, Investment. Please refer Investopedia or inform me if i am wrong. Draw a line from the $0,r_f$ point in your diagram such that it is tangent to your efficient frontier. WebTo find the portfolio constraining all the weights to sum to 1, it is as simple as dividing by the sum of the portfolio weights w m v, c w m v, u n c 1 w m v, u n c = 1 1 \end{align*}\], \[\begin{equation} \[\begin{align*} On the other hand, the tangency portfolio weights vary considerably throughout the time period considered, which can impose challenges in its maintenance as its turnover can be quite high. All the combinations of large stocks and the risk-free rate are dominated once we can combine small stocks and the risk-free rate to form portfolios of our choosing. L(\mathbf{t},\lambda)=\left(\mathbf{t}^{\prime}\mu-r_{f}\right)(\mathbf{t}^{\prime}\Sigma \mathbf{t})^{-{\frac{1}{2}}}+\lambda(\mathbf{t}^{\prime}\mathbf{1}-1). \end{align}\] \[ that efficient portfolios of two risky assets and a single risk-free What positional accuracy (ie, arc seconds) is necessary to view Saturn, Uranus, beyond? \end{equation}\], \(\mathbf{b} \triangleq\left(b_{1}, b_{2}, \ldots, b_{N}\right)\left(\text { with } \mathbf{1}^{T} \mathbf{b}=1 \text { and } \mathbf{b} \geq \mathbf{0}\right)\), \[\begin{equation} What's the most energy-efficient way to run a boiler? We want to compute an efficient portfolio that would be preferred Capital allocation here, now that we've found this tangency portfolio, we're just going to be making decisions, part in the risk-free rate, part in the tangency portfolio. Final General Portfolio Example and Tangency Portfolio We will first consider FAANG returns from 2018 to build the portfolios as follows: Fig. Using (12.35), the tangency portfolio satisfies: \[ This is the formula for the market portfolio, derived using the tangency condition. someone said the mean-variance efficient portfolio solutions based on the sample covariance matrix do not require the assumption of normality because Markowitz never assumed it either, Calculation of Market portfolio from efficient frontier, Improving the copy in the close modal and post notices - 2023 edition, New blog post from our CEO Prashanth: Community is the future of AI. by a highly risk tolerant investor.

Why are players required to record the moves in World Championship Classical games? \frac{\partial L(\mathbf{x},\lambda)}{\partial\lambda} & =\mathbf{x}^{\prime}\tilde{\mu}-\tilde{\mu}_{p,0}=0.\tag{12.32} Which ability is most related to insanity: Wisdom, Charisma, Constitution, or Intelligence? For you this time, let's calculate some Sharpe ratios. This is giving us the combination of large stocks and small stocks. You need $R_f$, which in your case is the LIBOR rate. you will with probability one get that rate for 1 month or 1 year. Furthermore, given any investment weight vector $\mathbb{w}$, the assets' expected return vector $\mathbb{\mu}$ and the assets' covariance matrix $\mathbb{\Sigma}$, our portfolio's expected return is: $$ Samirs calculation follows exactly the ex-post definition of the Sharpe ratio defined in Wikipedia. After much tedious algebra, it can be shown that the solution for Notice that Nordstrom, which has the lowest mean return, is sold short (12.8). free asset that achieves the target excess return \(\tilde{\mu}_{p,0}=\mu_{p,0}-r_{f}\) I would appreciate any help. \end{equation}\] \] Correlation of Asset 1 with Asset 2 - You can use the AssetsCorrelations spreadsheet to determine the correlation of the two assets using historical prices. Here is a review. Let's get to work back to the tablet here. Handout 7: Optimal portfolios when there is By the end of the Chapter, you will be able to create your own risk parity / All Weather fund and compare it against your benchmark of choice. WebSteps to Calculate Sharpe Ratio in Excel Step 1: First insert your mutual fund returns in a column. use: The tangency portfolio has weights \(t_{\textrm{msft}}=1.027,\) \(t_{\textrm{nord}}=-0.326\) of volatility. For sake of argument, let us assume that you have queried the LIBOR rates or any other interbank rates panel for the relevant risk free rates.*. $$. The tangency portfolio, combined with the risk-free asset, gives returns that dominate those offered by small stocks, as well as those offered by large stocks as individual assets. Proportion invested in the Asset 2 - This field contains the varying weights of Asset 2. Proportion invested in the Asset 1 - This field contains the varying weights of Asset 1. \left.\frac{\partial \mu_L}{\partial \sigma}\right|_M=\left.\frac{\partial \mu_p}{\partial \sigma_p}\right|_{M} solves the constrained maximization problem: Did the drapes in old theatres actually say "ASBESTOS" on them?

That was the question posed by Bridgewater Associates before creating the All Weather funds with concepts today popularized in the so-called risk parity strategies. Figure 3.3: In 1990, Dr. Harry M. Markowitz shared The Nobel Prize in Economics for his work on portfolio theory. \end{align}\], \(\mathbf{\tilde{R}}=\mathbf{R}-r_{f}\cdot\mathbf{1}\), \[\begin{align} No It is a research project. Remember the Sharpe ratio of a security and asset is the excess return of that security, in excess of the risk-free rate divided by its standard deviation. \end{align*}\], \[\begin{align} \mathbf{x}=-\frac{1}{2}\lambda\Sigma^{-1}\tilde{\mu}.\tag{12.33} Step 1: First insert your mutual fund returns in a column. We get this three percent return for sure. Let's remember these assumptions here and then go to our next pause, think, and answer. WebIn the portfolio, we can combine the two assets with different weights for each asset to create an infinite number of portfolios having different risk-return profiles. The higher the correlation, the lower the weight of asset 1. \[\begin{equation} \mathbf{x}=-\frac{1}{2}\lambda\Sigma^{-1}\tilde{\mu}.\tag{12.33} \], \[ which could occur when stock prices are falling and the economy is Huge real life value addition. Tangency portfolio and the risk-free rate combinations also dominates small stocks for the same standard deviation of 50 percent, we also get a higher return. Using (12.38) and solving for More on the tangency portfolio, large stocks I talked about you can see in the figure they're dominated asset. What are the advantages of running a power tool on 240 V vs 120 V? 3.5 shows the portfolio weights obtained for both the Parity and the Tangency portfolios. R_{p,x}=\mathbf{x}^{\prime}\mathbf{R}+x_{f}r_{f}=\mathbf{x}^{\prime}\mathbf{R}+(1-\mathbf{x}^{\prime}\mathbf{1})r_{f}=r_{f}+\mathbf{x}^{\prime}(\mathbf{R}-r_{f}\cdot\mathbf{1}). We test how the periodically calculated Minimum variance portfolio, Tangency portfolio and Maximum return portfolio with a given level of volatility (10% p.a.) \] portfolio (tangency portfolio) and the T-Bill. Thanks. All of the charts in this lesson were generated in this spreadsheet if you're interested. tangency portfolio \frac{\partial L(\mathbf{t},\lambda)}{\partial\mathbf{t}} & =\mu(\mathbf{t}^{\prime}\Sigma \mathbf{t})^{-{\frac{1}{2}}}-\left(\mathbf{t}^{\prime}\mu-r_{f}\right)(\mathbf{t}^{\prime}\Sigma \mathbf{t})^{-3/2}\Sigma \mathbf{t}+\lambda\mathbf{1}=\mathbf{0},\\ The unconstrained mean-variance problem $$w_{mv,unc}\equiv argmax\left\{ w'\mu-\frac{1}{2}\lambda w'\Sigma w\right\} The expected return-risk trade-off of these portfolios is given by is a very tedious problem. In this Chapter, we introduced the concept of risk parity portfolios and compare it against a mean-variance model. which we can use to solve for \(\lambda\): \mu_p(\mathbb{w})=r_f + \left(\mathbb{\mu}-\mathbb{1}r_f\right)^T\mathbb{w} \qquad portfolio (\(1-x_{t}\) represents the fraction of wealth invested in Course 3 of 7 in the Financial Management Specialization. The derivation of tangency portfolio formula (12.26) If you really hate risk, you're investing most of your money in the risk-free asset, if you like to take risks, maybe invest all your money in this tangency portfolio, or if you really like to take risk, you're skydiving as your hobby, that risk that you have that caused you to like to take skydiving, causing you wanting to take risky or financial portfolio. Figure 3.4: Efficienty Frontier. Calculating the efficient frontier from expected returns and SD, How to choose a tangency portfolio without a risk-free rate, CAPM - market portfolio vs real portfolio, Efficient frontier using Post Modern Portfolio theory. where \(f\) is a positively homogeneous function of degree one that measures the total risk of the portfolio and \(\mathbf{w}\) is the portfolio weight vector. On the other hand, the Parity portfolio presents a well-balanced distribution of weights among the FAANG companies with all company weights around 20%. and (12.28) can be re-expressed as: Note that \(\mathbf{x}^{\prime}\mathbf{1}=1\) is not a constraint because Given this (yet unknown) point, the formula for the capital market line $L$ is: $$ Web3.3 Tangency Portfolio Mean variance optimization is a commonly used quantitative tool part of Modern Portfolio Theory that allows investors to perform allocation by considering the trade-off between risk and return. Expected Return of Riskless Asset - This can be determined from the U.S Treasury Bills or Bonds. A cleaner solution is the following VBA function. 3 0 obj 1 0 obj \end{equation}\], \[\begin{equation} Excel That portfolio dominates small stocks. Are there any canonical examples of the Prime Directive being broken that aren't shown on screen? Then if we really like to take on risk, here we have an allocation that's 200 percent large, minus 100 percent the risk-free rate. looks similar to the formula for the global minimum variance portfolio This function can be called by giving it two arguments; the first is the range containing the investment returns, while the second range contains the risk-free interest rates. The best answers are voted up and rise to the top, Not the answer you're looking for? Specifically, we will learn how to interpret and estimate regressions that provide us with both a benchmark to use for a security given its risk (determined by its beta), as well as a risk-adjusted measure of the securitys performance (measured by its alpha). The over-arching goals of this course are to build an understanding of the fundamentals of investment finance and provide an ability to implement key asset-pricing models and firm-valuation techniques in real-world situations. The second equation (12.32) implies that \(\mathbf{x}^{\prime}\tilde{\mu}=\tilde{\mu}^{\prime}\mathbf{x}=\tilde{\mu}_{p,0}\). This is because every asset is susceptible to poor performance that can last for a decade or more, caused by a sustained shift in the economic environment - Bridgewater. \tilde{\mu}^{\prime}\mathbf{x=}-\frac{1}{2}\lambda\tilde{\mu}^{\prime}\Sigma^{-1}\tilde{\mu}=\tilde{\mu}_{p,0}, a combination with very little weight in the tangency portfolio and and the tangency portfolio. \min_{\mathbf{x}}~\sigma_{p,x}^{2}=\mathbf{x}^{\prime}\Sigma \mathbf{x}\textrm{ s.t. In this course, we will discuss fundamental principles of trading off risk and return, portfolio optimization, and security pricing. The expected return on the tangency portfolio, \mathbf{t}=\frac{\Sigma^{-1}(\mu-r_{f}\cdot\mathbf{1})}{\mathbf{1}^{\prime}\Sigma^{-1}(\mu-r_{f}\cdot\mathbf{1})}.\tag{12.26} Advance your career with graduate-level learning, Final General Portfolio Example and Tangency Portfolio, Two-Fund Separation Theorem and Applications.

Could a subterranean river or aquifer generate enough continuous momentum to power a waterwheel for the purpose of producing electricity? $$. There are some points, where, hey, we'd like to combine large and small stocks to get a portfolio with a higher return than we can obtain with trading off small stocks in the risk-free rate, for a given level of risk. Which was the first Sci-Fi story to predict obnoxious "robo calls"? Mutual Fund Separation Theorem Again Ecient Portfolios of T-bills and Risky assets are combinations of two portfolios Why refined oil is cheaper than cold press oil? This is not really too complex, but the ansatz is a different one based on a quadratic problem with linear (in-)equality conditions. illustrated in Figure 12.10. Or if we wanted to take on high risk, we would actually be borrowing at the risk-free rate so we can invest even more in the tangency portfolio. Ah, remember the good old days when risk-free rate was 5%? First, we will load log-returns of adjusted prices for FAANG companies, i.e., the stocks identified by the following tickers: FB, AMZN, AAPL, NFLX and GOOG (see Appendix B.2 for code used to generate this dataset). As expected, we observe that the Parity portfolio has a risk budget equally distributed among the portfolio assets. Again, we observe that the risk parity index presents a superior performance compared to the tangency portfolio index. Image of minimal degree representation of quasisimple group unique up to conjugacy. You can get this data from your investment provider, and can either be month-on-month, or year-on-year. This is demonstrated in Fig. Hence if all investors are rational and risk-averse, then the tangency portfolio will be the market portfolio. The Sharpe Ratio is a commonly used benchmark that describes how well an investment uses risk to get return. \], \[\begin{equation} To compute the tangency portfolio (12.26) This results in your tangency portfolio under non-negativity constraints. where \(x_{t}\) represents the fraction of wealth invested in the tangency At $M$, the portfolio volatility and the market volatility coincide, i.e. What is a tangency portfolio? - TimesMojo In other words, no investor should be holding a mutual fund that's 100 percent large or 100 percent small. in the tangency portfolio. This course is the first of two on Investments that I am offering online (Investments II: Lessons and Applications for Investors is the second course). You also have the option to opt-out of these cookies. in terms of \(\lambda\): Why don't we use the 7805 for car phone chargers? Can someone provides me with details about how can I calculate the market portfolio from the efficient frontier? \mu_{p}^{e} & =r_{f}+x_{t}(\mu_{p,t}-r_{f}),\tag{12.37}\\ The idea here is to build something that would work for everybody. i.e. Bloomberg / Quandl if this is a personal project. Necessary cookies are absolutely essential for the website to function properly. For my example, the formula would be =STDEV(D5:D16), Finally calculate the Sharpe Ratio by dividing the average of the Exess Return by its Standard Deviation (in my example this would be. }\mathbf{t}^{\prime}\mathbf{1}=1,\tag{12.25} $2,000 is invested in X, $5,000 invested in Y, and $3,000 is invested in Z.

To draw the tangent line, you need to know what the risk-free rate $R_f$ is. Here are the assumptions, same assumptions we had before. Note that you can also arrive at this result using a Lagrangian ansatz. You can see, if I had the choice, I would rather trade off small stocks and Treasury Bills than large stocks and treasury bills. $$. \(x_{t}\), the weights in the tangency portfolio and the T-Bill are: In this efficient portfolio, the weights in the risky assets are proportional If you just want the spreadsheet, then click here, but read on if you want to understand its implementation. again assuming a long-only constraint, the weights in the tangency portfolio would be now the other way around. Ultimatively, you could use your preferred non-linear optimizer and simply instruct it to maximize the Sharpe ratio s.t. A summation of values for each which implies that, https://CRAN.R-project.org/package=riskParityPortfolio. and our portfolio's volatility is: Stack Exchange network consists of 181 Q&A communities including Stack Overflow, the largest, most trusted online community for developers to learn, share their knowledge, and build their careers. \tilde{R}_{p,x} & =\mathbf{x}^{\prime}\tilde{\mathbf{R}},\tag{12.29}\\ Merton, Robert, 1972, An Analytic Derivation of the Efficient Portfolio Frontier, Journal of Financial and Quantitative Analysis One approach is to choose the most efficient portfolio from a risk/return standpoint, i.e., the portfolio with the highest Sharpe ratio (ratio between excess return and portfolio standard deviation). Surprisingly, the FAANG risk parity index outperforms the FAANG tangency portfolio index by quite a bit with a cumulative return of 169.482% versus 109.652% from the tangency portfolio index. well the tangent point ends up being on the lower half of the hyperbola instead of the upper half, so the portfolio is optimally inefficient. Capital Allocation Line (CAL) and Optimal Portfolio Understand market multiples and income approaches to valuing a firm and its stock, as well as the sensitivity of each approach to assumptions made This is known as L(\mathbf{x},\lambda)=\mathbf{x}^{\prime}\mathbf{\Sigma x+}\lambda\mathbf{(x}^{\prime}\tilde{\mu}-\tilde{\mu}_{p,0}). and prefers portfolios with very low volatility, then she will choose \[\begin{align*} $\sigma(w)\equiv \sigma_M$. That's our best opportunities. Portfolio The FAANG risk parity index also has a relatively lower drawdown across most of the period analyzed. That is to say, you can input your x-value, create a couple of formulas, and have Excel calculate the secant value of the tangent slope. \mathbf{1}^{\prime}\mathbf{t}=\tilde{\mu}_{p,t}\cdot\frac{\mathbf{1}^{\prime}\Sigma^{-1}\tilde{\mu}}{\tilde{\mu}^{\prime}\Sigma^{-1}\tilde{\mu}}=1, Investments I: Fundamentals of Performance Evaluation, University of Illinois at Urbana-Champaign, A Comprehensive Guide to Becoming a Data Analyst, Advance Your Career With A Cybersecurity Certification, How to Break into the Field of Data Analysis, Jumpstart Your Data Career with a SQL Certification, Start Your Career with CAPM Certification, Understanding the Role and Responsibilities of a Scrum Master, Unlock Your Potential with a PMI Certification, What You Should Know About CompTIA A+ Certification. \underset{\mathbf{t}}{\max}~\frac{\mathbf{t}^{\prime}\mu-r_{f}}{(\mathbf{t}^{\prime}\Sigma \mathbf{t})^{{\frac{1}{2}}}}=\frac{\mu_{p,t}-r_{f}}{\sigma_{p,t}}\textrm{ s.t.
