The Direxion Daily Semiconductor Bull 3X ETF, better known by its ticker SOXL, just reminded everyone why the phrase “3X leverage” should come with a siren sound. The fund dropped 16.38% in a single session on July 1, while the underlying semiconductor benchmark it tracks fell only about 5.68%.
SOXL aims to deliver 300% of the daily returns of the ICE Semiconductor Index. When chip stocks have a good day, SOXL triples the joy. When they don’t, it triples the pain.
The July 1 drop wasn’t even the worst session this year. On May 12, SOXL cratered as much as 20.9% intraday after negative inflation data hammered semiconductor stocks. The unleveraged iShares Semiconductor ETF (SOXX) fell roughly 7% that same day.
Here’s the thing most people miss about leveraged ETFs. They reset daily. That means the 3X multiplier applies to each individual trading day, not to cumulative performance over weeks or months. Over time, this daily compounding creates a phenomenon called “volatility decay” that can erode returns even when the underlying index eventually recovers to its starting point.
