Trading system commentary

43 closed trades | 47% winners

Both of our trading systems gave some gains back this month and trailed our 60/40 benchmark. Merlin felt the pressure at the start of the month due to its concentration in growth and technology stocks which sold off fairly aggressively in those first few weeks.

I tweeted out this on May 13 when Merlin was down about 10% for the month:

The goal isn’t to perfectly time my equity curve, rather, it’s to recognize more favorable times to bring cash off the sidelines. By the end of the month, it managed to claw back some of those losses to finish down -3.26%.

Lamorak also got a little chopped up this month and couldn’t quite string together enough consecutive winners. Typically, more volatility and range bound trading is when this system does best, but that’s obviously not always a guarantee.

All in all, both systems are doing great year-to-date in terms of performance and continue to perform as expected given market conditions.
