## Do all securities lie on the security market line?

The security market line is the theoretical line on which all capital investments lie. Given two investments with the same expected return, investors would always choose less risk.

**Do all assets lie on the same SML?**

All the correctly priced securities are plotted on the SML. The assets above the line are undervalued because for a given amount of risk (beta), they yield a higher return.

**What is the intercept on the security market line?**

The intercept of the security market line (SML) is the risk-free rate and the slope is the market risk premium. The relationship between the risk and return described by the SML is the Capital Asset Pricing Model (CAPM).

### What does security market capture?

The security market line (SML) is a line drawn on a chart that serves as a graphical representation of the capital asset pricing model (CAPM)—which shows different levels of systematic, or market risk, of various marketable securities, plotted against the expected return of the entire market at any given time.

**How do you read a security market line?**

The two-dimensional correlation between expected return and beta can be calculated through the CAPM formula and expressed graphically through a security market line, or SML. Any security plotted above the SML is interpreted as undervalued. A security below the line is overvalued.

**How do you use the security market line?**

Security Market Line = Risk-Free Rate + [Beta * (Expected Market Return – Risk-Free Rate)]

- Risk-Free Rate – Current risk-free rate.
- Beta – Beta of the security to the market.
- Expected Market Return – Expected return of all risky assets.

## Can SML be negative?

The SML is unique in a space. 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.

**What does the slope of SML represent?**

The slope of the security market line represents the market risk premium, i.e. the excess return over the market return. Therefore, the higher the risk, the higher the market risk premium for the security, and the higher the expected overall return for the security.

**Is positive alpha overpriced?**

According to the Capital Asset Pricing Model (CAPM), a. a security with a positive alpha is considered overpriced. a security with a zero alpha is considered to be a good buy.

### How is capital market line calculated?

The Capital Market Line (CML) formula can be written as follows:

- ERp = Rf + SDp * (ERm – Rf) /SDm
- Suppose that the current risk-free rate is 5%, and the expected market return is 18%.
- Calculation of Expected Return of Portfolio A.
- Calculation of Expected Return of Portfolio B.

**What are the components of security market line?**

Security Market Line = Risk-Free Rate + [Beta * (Expected Market Return – Risk-Free Rate)]

- Risk-Free Rate – Current risk-free rate.
- Beta – Beta of the security to the market.
- Expected Market Return – Expected return of all risky assets.

**Can SML be downward sloping?**

To be specific, following high market-wide trading volume, the slope of the SML line becomes more downward sloping, indicating a stronger (conditional) low-beta anomaly (i.e., low-beta stocks outperform high-beta ones).

## Is the security market line above or below the market?

Graphically, if the asset offers a return that is higher than the market’s for a given level of systematic risk, it will be plotted above the security market line. However, if the asset offers a return that is lower than the market’s for a given level of systematic risk, it will be plotted below the security market line.

**How is the security market Line ( SML ) calculated?**

The security market line (SML) is a line drawn on a chart that serves as a graphical representation of the capital asset pricing model (CAPM). 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

**Why are assets plotted above the security market line?**

If an asset is plotted above the security market line, it is underpriced. If an asset is plotted below, it is overpriced. The intuitive reason why an asset that is plotted above the SML is underpriced is that it is giving a return larger than the market, and it is because the cost of buying the asset is not large enough.

### What happens when the price of a security goes up?

There is a tradeoff between a security’s price and its expected return. If the price of the instrument goes up, its expected returns go down, and vice versa. A firm that is raising capital would like to sell these instruments for a high price, and investors want to buy them for a low price.
