Program tradingProgram trading• Program trading is casually defined as

the use of computers in stock markets to engage in arbitrage and portfolio insurance strategies. However, the New York Stock Exchange (NYSE) defines the term as "a wide range of portfolio trading strategies involving the purchase or sale of 15 or more stocks having a total market value of $1 million or more" without any direct reference to the use of computers

• The word "program" can be interpreted in its earlier, more general meaning of a defined and pre-arranged sequence of steps, rather than specifically a computer program. Some program trading strategies are subject to regulatory restrictions. For instance, NYSE Rule 80A requires index arbitrage trades to be marked when submitted.

Impact of program trading Impact of program trading on stock volatilityon stock volatility

• Program trading has developed because of three interrelated conditions.

• First, individual investors are learning that trading a diversified portfolio of securities eliminates some of the risks of investing in individual stocks.

• Second, institutions hold and trade a higher fraction of equity than ever before. These professional investors execute their diversified trades directly in the stock market as program trades or in the futures and options markets, where investors or speculators can trade contracts that are tied to changes in market indexes.

• Third, technological advances have reduced trading costs.

Capital Asset Pricing Model Capital Asset Pricing Model (CAPM)(CAPM)

– Used to estimate the required return on publicly traded stock

– Assumes that the only relevant risk is systematic (market) risk

• Uses beta to measure risk rather than standard deviation of returns

Determining the Required Rate of Determining the Required Rate of Return to Value StocksReturn to Value Stocks

Rj = Rf + j(Rm – Rf)

• Capital Asset Pricing Model (CAPM)– Estimating the risk-free rate and the

market risk premium• Proxy for risk-free rate is the yield on newly

issued Treasury bonds• The market risk premium, or (Rm-Rf), can be

estimated using a long-term average of historical data.

Determining the Required Rate of Determining the Required Rate of Return to Value StocksReturn to Value Stocks

Rj = Rf + j(Rm – Rf)

– Estimating the firm’s beta• Beta measures systematic risk• Reflects how sensitive individual stock’s returns

are relative to the overall market• Example: beta of 1.2 indicates that the stock’s

return is 20% more volatile than the overall market

Arbitrage Pricing ModelArbitrage Pricing Model

– Differs from CAPM in that it suggests a stock’s price is influenced by a set of factors rather than just the return on the market

– Factors may include things like:• Economic growth• Inflation• Industry effects

– Problem with APT: factors are unspecified and must be defined

Where E(R)= expected return of assets

0B = a constant

nFF ...1 =values of factors 1 to n

iB = sensitivity of the asset return to particular factor

ju = residual term

• This model suggest that in equilibrium , expected returns on assets are linearly related to the covariance between assets returns and the factors (differ to the CAPM).

• Similar to the CAPM, the unique effects are independent and will be diversified away in a large portfolio.
