If 439.66 doesn't recover tomorrow, next stop seems like 437.45. I did expect another attempted rally this month, so I'm still waiting for that and looking for opportunities to add bullish positions. I added UPRO yesterday when SPY was at 442.46, added more again at 439.66, and will add more tomorrow if we test 437.45. If we lose that, we'll likely see 429.70. I've been saying for a couple months now that I expect to hold SPXU until the end of the year, but I may close half and try and get an even lower entry if SPY puts in a good floor. Since SPY broke out of the trend line, I think it's fair to say the short-term trend is down now. A multi-day floor is important in order to rally with confidence.
Good luck to all the rest of the week!
