If I were enough of an idiot to trade FOMC, I'd be buying up SARK and SQQQ before the bell today.
I don't love what's going on here. It looks similar to the last two CPI days and suggests that shorts wised up and caught on to the idea that you often see hedges get dropped off events, which leads to the market going higher.
Cover your shorts, wait for the news, then reshort, rinse and repeat unless you get caught with your pants on the ground like what happened on January 28th this year. It may have to take a surprise like that (maybe this month's rebalance would do it, as the rebalance in December 2018 and March 2020 helped with big bounces) to throw things off, and then it could just be for a couple of weeks.
