Trading system commentary

We got ourselves a performance race! Lamorak had a very strong month for March, closing up 9.58% which puts Merlin and Lamorak at nearly identical spots in terms of year to date 2021 performance.

I think it’s important to note that each trading system has put in strong performance at different times. Merlin started the year strong while Lamorak started slow, and now they’ve switched places. That’s something easily missed if you’re evaluating a trading system using end of year numbers only. The truth is, when you’re actually trading month to month, having systems that are strong and weak at different times is a great psychological and portfolio benefit.

Heading into April, Merlin is still aggressively long this market and Lamorak is much more tactical picking its spots carefully.
