Performance Disclosures

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

We use 2 backtesting and simulation engines to develop our trading systems: NinjaTrader and TuringTrader and we'll typically code strategies in both environments to be confident in our results.

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.

Backtests & Simulated Returns: Merlin: January 2006 through October 2019 and Lamorak: January 2006 through September 2020 performance is based on backtests and simulated trading and reported on a closing trade basis. All tests use survivorship bias free, total return, split adjusted Nasdaq 100 and S&P100 stocks for the trading universe. Tests include slippage and normal market impact of entering/exiting positions. Tests do not include: trading commissions, interest earned on idle cash balance, rotation into treasury or bond funds during periods where the strategy is not invested, or any borrow costs which is only applicable to the margin portfolio when the strategy is taking advantage of leverage.
