Our read on each fund
SDSB
SPDNA
In short
SDS The middle setting on the bear-S&P dial: SDS aims for two times the inverse of the S&P 500's daily move, before fees. Running since 2006, it resets every close, which makes it a trading tool, not a parking spot.
SPDN A bet against the S&P 500 without the leverage: SPDN aims for the index's daily move in reverse, one for one, at 0.48% net of a waiver through September 1, 2027, the lowest fee in its short-S&P group.
Stated mandate
SDS The fund seeks daily, before-fee-and-expense returns equal to two times the inverse of the daily performance of the S&P 500 Index.
SPDN The fund seeks daily results equal to 100% of the inverse performance of the S&P 500® Index, before fees and expenses.
