1.) Preferred scenario would be for the spy to pullback down to 400-398 or trendline and hold for the rally to continue to the upside. So a pullback or consolidation around this level is healthy. Just remember its December, I always look forward to the Santa Rally if you've been in the market more than a year or two you know what that means.
2.) If SPY Pulls back and breaks this trendline and strong support, FEAR / FOMO / SQUIZZLE can happen and the bear market continues.
We don't know exactly whats gonna happen in the market but we just ride the wave and make mullah along the way 🙂
