Our read on MYY

ETF.net Research

In short

CThe only -1x ETF built on the S&P MidCap 400, trading since 2006. One ticker, one dose of inverse exposure to America's mid caps, and a target that resets at every close.

Stated mandate

MYY seeks daily investment results, before fees and expenses, that correspond to the inverse (-1x) of the daily performance of the S&P MidCap 400.

Why people hold it

  • Inverse funds pile into the S&P 500, Nasdaq and Dow. MYY is the only -1x ETF designed to rise when the S&P MidCap 400 falls on the day, so the mid-cap slice gets its own ticker.proshares.com
  • 0.95% net of a waiver through September 30, 2027, near the typical inverse-fund fee and level with stablemates DOG and PSQ (each 0.95% net of waivers through September 30, 2027).
  • Short exposure without a margin account or a borrow: you buy and sell it like any stock, and it has been doing this job since 2006, a long run for a daily-reset product.proshares.com

Worth knowing

  • The target is one day's inverse move, reset at each close. Hold longer and compounding takes over, so multi-day results can differ from -1x the index's move over that stretch.
  • That 0.95% leans on a fee waiver running through September 30, 2027. The gross expense ratio underneath is 2.95%.
  • Small and thinly traded next to the headline inverse names, so spreads and limit orders matter more. Sibling MZZ targets -2x of the same index, with bigger daily swings.proshares.com

This fund targets a multiple of the daily move of its index and resets daily. Hold it longer than one reset and compounding makes the return diverge from that target. In choppy markets it can lose value even when the index ends flat.

14.8%
Annualised · 36 months to Oct 2026
How it’s calculated: standard deviation

The sample standard deviation of monthly total returns, multiplied by the square root of 12.

Uses up to 36 complete months, with at least 12 required. Total returns include reinvested distributions.
