Another Key to Position Sizing
Update: 2025-09-12
Description
On today’s From Theory to Practice, the market just continues its incredible run higher, with both the S&P 500 and Nasdaq hitting fresh, all-time highs. In our portfolio, both the ADBE and SPX Expected Move Butterflys didn’t pan out, and we’re also getting hurt on our BBY, CMG, GOOGL, and SBUX positions. In other words, today is one of those days where a lot of things went wrong, which gives yet another great example of why it’s so important to control position sizing on entry.
