Big drops are normal for some funds. They matter because selling during a drop locks in the loss.
What does SSO hold?#
This fund aims to return 2 times the S&P 500’s return for a single day, using stocks plus swaps and other contracts. It resets every day, so over weeks or years its results can be very different from 2 times the index, and losses can be large. It is built for daily moves, not as a plain long-term index fund.
It tracks the S&P 500.
What is the SSO expense ratio?#
SSO charges 0.84% a year. An expense ratio is the yearly fee a fund takes to run itself. On $10,000, a 0.84% fee comes to about $84 a year. Of the 162 ETFs on Tactfolio, 1% charge more.
You never get a bill for it. The fund takes the fee out of its own value a little each day.

Tactfolio is a platform where you build rules-based investing strategies, backtest them on decades of real prices, share them, and run them automatically in your own Alpaca account.

The details#
Prices come from Tactfolio’s stored daily prices for SSO and SPY. Each close is adjusted for splits, and dividends are reinvested on the day the fund pays them out. CAGR is the steady yearly return that turns the starting value into the ending value. Volatility is the yearly standard deviation of daily returns. Beta and correlation compare daily returns with the S&P 500 over the same dates.
