It is very important to us that you fully understand how we compute the performance statistics for our trading systems. The following definitions and disclosures will give you all of the details behind our calculations. Please remember, past performance is not a guarantee of future results. If you have any questions please use the contact page to reach us.
How we backtest
For market data, we use Norgate for total return split-adjusted stock market data with historical market constituents.
Benchmark and portfolio statistics
We use a 60/40 stocks/bonds portfolio to benchmark against our trading systems. We simulate the 60/40 monthly returns using total return SPY and total return IEF ETFs. For long-term benchmark statistics (over 12 months) we use the VBINX mutual fund by Vanguard to determine Sharpe, drawdowns, etc.
Merlin and Lamorak Sharpe Ratio: is based on strategy monthly returns and a risk-free rate of t-bills via FRED.
Portfolio constructs and universe definitions
Merlin Margin Portfolio: An "aggressive" portfolio that is constructed taking all available strategy signals and borrows up to 50% on margin for a total exposure of 150%. Each individual signal is position sized approximately 50% larger than the Merlin IRA Portfolio.
Merlin IRA Portfolio: A "moderate" portfolio that is constructed taking all available strategy signals until 100% of the cash is invested. Each individual signal is position sized approximately 50% smaller than the Merlin Margin Portfolio.
