A holder who started Friday, June 5, 2026 with $10,000 in ProShares Ultra Technology (NYSEARCA:ROM) ended the day with about $8,655. The fund opened at $161.98 and closed at $140.20, a single-session loss of 13.45%. Over the same five trading days, ROM gave back 11.8%, with the week starting at $158.95. Those numbers are what a 2x daily tech ETF does on the worst day the sector has had in over a year.
The math is almost embarrassingly clean. ROM is structured to deliver twice the daily return of the Dow Jones U.S. Technology Index. The Technology Select Sector SPDR Fund (NYSEARCA:XLK), the standard reference for the same basket, fell roughly 7% on June 5, opening near $193 and closing at $180. Double that and you get the ROM print, give or take a few basis points of fees and tracking. That is the entire arithmetic of the day, and it tells you almost nothing about why the move happened. To understand that, you have to look at who is inside the fund.
