Using the MFI indicator on the 4D chart, you can see that past OB readings (orange boxes) were highly correlated with price corrections. I expect a correction soon, but it might not happen until after Trump is inaugurated. I would express this thesis with an out-of-the-money put with expiration between June 2025 and January 2026.
This is a simple mean-reversion bet. As you can see, it's rare for the index to go more than 800 days without revisiting this long-term trendline. There's nothing special about the trendline, it's just a moderately aggressive rate of price appreciation that fits the log chart pretty well. I would trade this idea by purchasing a SPY 455 Put with April 2025...
