CML is a special case of the CAL where the risk portfolio is the market portfolio. Thus, the slope of the CML is the Sharpe ratio of the market portfolio. As a generalization, buy assets if the Sharpe ratio is above the CML and sell if the Sharpe ratio is below the CML.
What does the slope of the CML tell us?
So, the slope of the CML is the Sharpe ratio of the market portfolio. As a generalization, investors should look to buy assets if the Sharpe ratio is above the CML and sell if the Sharpe ratio is below the CML. How is capital allocation line (CAL) related to CML?
How do you find the slope of a line?
You can find the slope of any line by following these three easy steps: Step One: Determine if the slope if positive (increasing) or negative (decreasing)
How does the slope of SML change with time?
The slope of SML, i.e., market risk premium and the beta coefficient, can vary with time. There can be macroeconomic changes like GDP growth, inflation, interest rates, unemployment, etc. which can change the SML. The significant input of SML is the beta coefficient; however, predicting accurate beta for the model is difficult.
What determines the slope of the security market Line (SML)?
The slope of the Security Market Line is determined by market risk premium, which is: (E (R M) – R f ). Higher the market risk premium steeper the slope and vice-versa All the assets which are correctly priced are represented on SML. The assets above the SML are undervalued as they give the higher expected return for a given amount of risk.
What is capital market line slope?
The slope of a capital market line of a portfolio is its Sharpe Ratio. We know that the greater the returns of a portfolio, the greater the risk. The optimal and the best portfolio is often described as the one that earns the maximum return taking the least amount of risk.

How do you calculate SML slope?
The SML can help to determine whether an investment product would offer a favorable expected return compared to its level of risk. The formula for plotting the SML is required return = risk-free rate of return + beta (market return - risk-free rate of return).
Can the CML have a negative slope?
The could be expressed as . The two curves are equivalent only if (i.e., portfolio i is perfectly correlated with the market portfolio); if , and E(Ri) is equal, the CML has a higher slope with respect to the SML; with , the SML will have a negative slope.
How is SML derived from CML?
In SML, the formula to calculate slope is (Rm – Rf), while the formula in CML is (Rm – Rf) / σm. The slope in SML tells the difference between the required rate of return and the risk-free rate.
What is the difference between SML and CML?
Summary: 1. The CML is a line that is used to show the rates of return, which depends on risk-free rates of return and levels of risk for a specific portfolio. SML, which is also called a Characteristic Line, is a graphical representation of the market's risk and return at a given time.
What is the slope of the security market line SML quizlet?
The slope of the SML, which is the difference between the expected return on a market portfolio and the risk-free rate. In other words, it is the reward investors expect to earn for holding a portfolio of beta of 1.
Does the CML always have a positive slope?
III) The CML is also called the security market line. IV) The CML always has a positive slope.
What is the measure of risk in CML?
And while the measure of risk in the CML is the standard deviation of returns (total risk), the risk measure in the SML is systematic risk, or beta. Securities that are fairly priced will plot on the CML and the SML.
What does it mean when a stock plots above the CML?
Securities that plot above the CML or the SML are generating returns that are too high for the given risk and are underpriced . Securities that plot below CML or the SML are generating returns that are too low for the given risk and are overpriced.
What is the difference between CML and SML?
The CML is sometimes confused with the security market line (SML). The SML is derived from the CML. While the CML shows the rates of return for a specific portfolio, the SML represents the market’s risk and return at a given time, and shows the expected returns of individual assets. And while the measure of risk in the CML is the standard deviation of returns (total risk), the risk measure in the SML is systematic risk, or beta. Securities that are fairly priced will plot on the CML and the SML. Securities that plot above the CML or the SML are generating returns that are too high for the given risk and are underpriced. Securities that plot below CML or the SML are generating returns that are too low for the given risk and are overpriced.
What is a CML portfolio?
Portfolios that fall on the capital market line (CML), in theory, optimize the risk/return relationship, thereby maximizing performance. The capital allocation line (CAL) makes up the allotment of risk-free assets and risky portfolio for an investor. CML is a special case of the CAL where the risk portfolio is the market portfolio. Thus, the slope of the CML is the Sharpe ratio of the market portfolio. As a generalization, buy assets if the Sharpe ratio is above the CML and sell if the Sharpe ratio is below the CML.
Example
In the example of efficient frontier, we identified a set of portfolios that offer same risk-return trade-off. Let’s combine risk-free asset with expected return of 3% with the portfolio B and D.
Capital Allocation Line vs Capital Market Line
The captial allocation line is a graph that represents the risk and return profile of a portfolio that is a combination of the risk-free rate and ANY portfolion on the efficient frontier.
How to find the slope of a line?
You can find the slope of any line by following these three easy steps: Step One: Determine if the slope if positive (increasing) or negative (decreasing) Step Two: Using two points on the line, calculate the rise and the run and express it as a fraction (rise over run). Step Three: Simplify the fraction if possible.
What is slope in math?
Slope Definition: The slope of a line refers to its direction and steepness. There are 4 kinds of slope: positive, negative, zero, and undefined. In this guide, we are only going to look at positive and negative slope. Click here to watch a video tutorial review of the 4 kinds of slope. Note that positive slopes increase from left to right ...
What Is the Capital Allocation Line (CAL)?
The capital allocation line (CAL), also known as the capital market link (CML), is a line created on a graph of all possible combinations of risk-free and risky assets. The graph displays the return investors might possibly earn by assuming a certain level of risk with their investment.
Understanding the Capital Allocation Line (CAL)
The capital allocation line aids investors in choosing how much to invest in a risk-free asset and one or more risky assets.
Constructing Portfolios With the CAL
An easy way to adjust the risk level of a portfolio is to adjust the amount invested in the risk-free asset. The entire set of investment opportunities includes every single combination of risk-free and risky assets.
The Slope of the CAL
The slope of the CAL measures the trade-off between risk and return. A higher slope means that investors receive a higher expected return in exchange for taking on more risk. The value of this calculation is known as the Sharpe ratio .
Characteristics
SML is a good representation of investment opportunity cost, which provides a combination of the risk-free asset and the market portfolio.
Security Market Line Example
Let the risk-free rate by 5%, and the expected market return is 14%. Consider two securities, one with a beta coefficient of 0.5 and other with the beta coefficient of 1.5 with respect to the market index.
Slope of Securities Market Line (Beta)
Beta (slope) is an essential measure in the Security Market Line equation. Thus let us discuss it in detail:
Advantages
Since the SML is a graphical representation of CAPM, the advantages and limitations of SML are the same as that of the CAPM. Let us look at the benefits:
Limitations
The risk-free rate is the yield of short-term government securities. However, the risk-free rate can change with time and can have even shorter-term duration, thus causing volatility
Conclusion
SML gives the graphical representation of the Capital asset pricing model to give expected returns for systematic or market risk.

Passive and Active Portfolios
If the market is informationally efficient, then the quoted price of a security in the market is an unbiased estimate of all the future discounted cash flows and reflects all publicly known information about the security. If all security prices reflect all publicly available information, then, in theory, there is no way to outperform the market.
The Market
The market includes all risky assets or anything that has value – stocks, bonds, real estate, human capital and commodities. These assets are all defined in “the market.” Not all market assets are tradable or investable.
The Capital Market Line (CML)
The Capital Market Line (CML) is a special case of the CAL, that is, the line which makes up the allocation between a risk-free asset and a risky portfolio for an investor. In the case of the CML, the risk portfolio is the market portfolio.
Question
What happens to the portfolio risk and return respectively as an investor moves up the CML?
Portfolio expected return and variance
For the sake of simplicity, we will construct a portfolio with only two risky assets.
The efficient frontier
A portfolio frontier is a graph that maps out all possible portfolios with different asset weight combinations, with levels of portfolio standard deviation graphed on the x-axis and portfolio expected return on the y-axis.
Complete portfolio and capital allocation line
In constructing portfolios, investors often combine risky assets with risk-free assets (such as government bonds) to reduce risks. A complete portfolio is defined as a combination of a risky asset portfolio, with return Rp, and the risk-free asset, with return Rf.
Optimal portfolio
The optimal portfolio consists of a risk-free asset and an optimal risky asset portfolio. The optimal risky asset portfolio is at the point where the CAL is tangent to the efficient frontier. This portfolio is optimal because the slope of CAL is the highest, which means we achieve the highest returns per additional unit of risk.
Summary of capital allocation line
Investors use both the efficient frontier and the CAL to achieve different combinations of risk and return based on what they desire. The optimal risky portfolio is found at the point where the CAL is tangent to the efficient frontier. This asset weight combination gives the best risk-to-reward ratio, as it has the highest slope for CAL.
