SPY is still structurally bullish, holding inside an upward expansion channel and consolidating just beneath the key 700 breakout zone rather than showing true topping behavior. The repeated compression between roughly 684 and 699 suggests energy building for a continuation move, with 678 acting as the critical support that must hold to keep the trend intact and 669 marking real structural failure. As long as price remains above these supports, the path of least resistance points higher toward the projected extension region around 708, then 721, and potentially the low-730s, implying this is more likely a late-trend pause before another upward impulse rather than the start of a broader reversal.
