Sharpe, John Lintner and Jan Mossin developed the capital asset pricing model CAPM to determine the theoretical appropriate rate that an asset should return given the level of risk assumed. The APT introduced a framework that explains the expected theoretical rate of return of an asset, or portfolio, in equilibrium as a linear function of the risk of the asset, or portfolio, with respect to a set of factors capturing systematic risk. Capital Asset Pricing Model The CAPM allows investors to quantify the expected return on investment given the investment risk, risk-free rate of returnexpected market return and beta of an asset or portfolio. The risk-free rate of return that is used is typically the federal funds rate or the year government bond yield.
Arbitrage Pricing Theory APT In the capital asset pricing model CAPMwe look at how the interrelationship between securities contributes to the risk and, as a result, the expected return of a security. Some factors are unsystematic - they only affect a single stock.
These are factors such as the success of a company's research and development. Other factors are systematic - these factors affect more than one stock at the same time.
Systematic risk is often referred to as market risk, and includes things such as inflation and interest rates. Using the APT, we see that the interrelationship between securities is dependent on the extent that these securities are affected by the same systematic factors. We therefore break the return of a stock into two main parts: That is to say, if a stock's return was always the same as its expected return - there would be no risk.
This new information is often given in the form of an announcement. Here we have to be careful, because not all information provided in an announcement is unexpected.
For example, the Federal Reserve might announce an interest rate hike on T-Bills from 1. Investors may have already expected an interest rate hike of 0. The portion of the information therefore that is a surprise, is a factor in the unexpected return - in this case, the 0.
Like the CAPM, we use a beta coefficient to represent how the price of a stock moves relative to surprise factors that make up the systematic risk.
The subscripts r and IP refer to unexpected change in interest rates and unexpected change in industry production respectively. As you can imagine, a factor model like the APT can be built with many different factors, and no one model is the right model.
Using the APT, we can also build a model for the return for a portfolio. The return on a portfolio is equal to the weighted average of the returns on each individual stock, where X represents the proportion each stock is weighted in a portfolio.
Here we want to use a one-factor model to simplify things. As we can see, the return on a portfolio is related to three sets of parameters: In fact, the larger a portfolio is, the more the unsystematic risks of each stock counteract one another - eventually, with a large enough portfolio, 3 will be equal to zero.
Let's take a look back at the security market line we introduced under CAPM. Security P represents our large portfolio in this case, the market portfolioor a security with equal beta and return to it.
An investor can either invest in our portfolio, or in a combination of some other security and a riskless asset. An investor looking for higher risk, and higher returns, may invest in security A or B, or may leverage her investment by borrowing at the risk-free rate and investing in P.
A low risk investor may invest in P, or may invest in some combination of A or B and a risk-free asset. No matter her risk tolerance, she can find a combination that suits her.
Now consider security C. No investor would invest in a security with that much risk and only so much return. This security is overpriced, and in a competetive market its price will fall until it matches the security market line. A stock that has a beta of zero in this example always returns the expected return in our one-factor model.
Similarly, for our very large portfolio, the weighted average of the betas of our portfolio will be equal to one.
We could have a portfolio at A or B if we wanted to take on more risk, but let's say we're the average investor, so we want to invest at P. In fact, the stocks at A or B will have some beta higher than one.
We can use this beta to determine the expected return for these stocks or portfolios. We know this relationship exists, because these portfolios can be duplicated by borrowing at RF and buying P: Therefore, we end up with a relationship that looks like this, where is the expected return of any security lying on our security market line.
Does this look familiar? The capital asset pricing model uses beta to measure a security's responsiveness to movements in the market portfolio; whereas the APT uses beta to measure a security's responsiveness to different factors.
When we use a one-factor APT model, we end up with a very similar formula to the capital asset pricing model. Computing Net Profit for Customer Wizard Corporation has analyzed their customer and order handling data for the past year and has determined the following costs: The average bid received for the auction implied a yield of 3.
