What is a leveraged ETF, and why can a "3x" fund fall so much more than the market it

follows?

On Thursday, Oct 22, chip stocks had a rough day: the PHLX Semiconductor Index fell 6.7%, its biggest one-day drop since June 23, according to Reuters. The iShares Semiconductor ETF (SOXX) fell nearly 7%, but SOXL, a fund built to deliver three times the daily move of a semiconductor index, dropped more than 20%. That's a leveraged ETF: a fund that typically uses derivatives such as swaps and futures to magnify one day's move, up or down.

The key word is "daily." Most leveraged ETFs reset every day, so they aim for 3x of a single day's move, not 3x over weeks or months. Compounding changes the math: if an index rises 10% one day and falls 10% the next, it ends down 1%. A 3x fund over those same two days would go up 30% and then down 30%, ending down 9%. The SEC's investor bulletin gives a real example where a 3x fund fell 53% over four months while its index actually gained about 8%.

That's why the SEC and FINRA say these products generally aren't meant for buy-and-hold investors, and why losses can be large and sudden when markets are volatile. This isn't a suggestion to buy or avoid any fund; it's about knowing how a product works before you ever trade it. Got a question about ETFs, leverage or compounding?
