What is Capital Asset Pricing Model or CAPM?
As an arbitrageur, you should always be well aware of the way bankers value their assets and what rate of return they expect from them. The Capital Asset Pricing Model or CAPM is the industry standard for pricing the future market return of an investment security.
The value of the Formula CAPM is that; internally accounts for the many market risks that investors are exposed to, like systematic risks because when the market goes down all correlations (beta) goes to one (1). The framework of the return of investment of the Capital Asset Pricing Model equation is that the individual investor can compare the future performance of a single equity name or fund versus the risk free return of treasury bills (^TNX).

Risk Free Rate vs. Market Return
William Sharpe formulated the equation to compare the risk relationship of expected market returns of a diversified portfolio; and is the fundamental base for Arbitrage Pricing Theory ATP. But we are only going to focus on single names stocks that pay a high dividend yield. In order to explain the changes we are going to apply; to the commonly used modern portfolio theory formula, we need to explain the original equation:
Capital Asset Pricing Model Formula
- First Step: you have to begin with the risk-free rate (Rf) the yield of a ten years government bond. Now in the Arbitrageur Capital Asset Pricing Model Instead using the coupon rate of the bond we are going to use the effective saving which is calculated by subtracting(^TNX- consumer price index CPI)
- Second Step: input the Market Beta (B): beta assess the stock market risk correlation. It measures the relative volatility of how stocks may go “bullish”, a positive +1 or higher correlation; or “bearish” a negative -1 or lower correlation towards the whole flow of the S&P 500 index. But since we are going to arbitrage with a single name security we are going to use the beta of the specific stock.
- Third Step: research the expected market return (Erm). Market investing exposes you to the risk of losing your original capital. We must demand a higher compensation for our exposure, a “risk premium”. But in the new application we are going to use the yield of our fund as the risk premium value.

The Bottom Line
As part of your investing process you should always account for market risk. Using the Capital Asset Pricing Model can give you an advantage at the time of making your buy and sell decisions because it gives you the opportunity of predicting your future return on investment ROI.
