Good question. So few discuss actual returns I don't really know how most other traders do. I know returns in the 100's of % are possible and that losses, or at least underperforming the market are more common. This year I updated my spreadsheet so I could better track my results, trade by trade and across accounts.
Using these metrics: Annualized Gain, Sharpe, Profit Factor, Correlation to market, Weekly Standard Deviation, Max Drawdown. For the period from 12/31/2008 thru 5/21/2010. I beat buy and hold a number of ways:
1. Buy and hold a set of diversified, uncorrelated (as much as possible) ETF's, with a low allocation (33% target) to equity. Rebalanced no more than annually:
12%, .89, 1.4, 67%, 1.8%, -8.8%
2. Long term trend following in mutual funds with a minimum 30 day hold period and generally less than 10 trades per year:
12%, 1.07, 1.53, 53%, 1.5%, -6.6%
3. Active stock trading, buying weakness, selling strength, and buying stocks based on quantified factors, such as momentum, value, earnings, volume, etc. Hold time days to weeks. Hundreds of trades per year:
61%, 2.45, 2.12, 20%, 3.4%, -20%
For comparison, the market as measured by VTI (Total Stock Mkt):
15%, .60, 1.28, 100%, 3.4%, -28.9%
The people that buy and hold and say trading is risky have it backwards. They are taking the big risks. Good trading strategies can greatly reduce the risks and/or increase the returns.
My sharpe calculation is just Annualized Return/Annualized StdDev, ignoring risk free interest rate, so not comparable to others. Profit factor is Total gains/Total losses.
