I am examining the behavior of an exponential moving average mechanical trading system using historical price data of CV Therapeutics, Inc. stock symbol CVTX. Price data begins 19 November 1996 ends 14 June 2007. Position size = (3 % of equity) / (10 x 20 day average true range). This system buys when closing price is greater than the 90 day exponential moving average value and sells when closing price is less than the 90 day exponential moving average value.
The system does not show a buy signal now. I observe the most recent sell signal 26 January 2007.
Lots of different exponential moving average values show profitable results by this trading simulation. The greatest profit of the exponential moving average values that I examine appears at 90 days.
Dollar position size is about 10 % to 20 % of capital. About 80 to 90 % of capital remains as cash, available for other trades. Growth rate of about 14 % represents growth of initial $ 100000 account. Other securities can add to the overall growth rate. The greatest draw down might decrease as a result of the portfolio effect.
