One thing I’ve noticed from trading more actively is how quickly market narratives turn over.
Themes used to have real staying power. Now the market can move on within weeks. I’m not sure how much of this is driven by AI, but the pattern is hard to miss: software gets sold at a record pace, attention shifts to high-short-interest names, and everyone is already searching for the next bottleneck or story.
According to J.P. Morgan, weekly retail outflows from software and services recently hit their highest level since the data series began. At the same time, social-media interest was clustering around high short interest names like GRND, RH, NBIS, and CAKE, alongside memory, AI infrastructure, and space names like SNDK, MU, VRT, and RKLB.
It doesn’t feel like capital is rotating neatly from one theme to the next. It feels more like several stories are lighting up and burning out at once. Sometimes the entire market seems to trade like a meme. Positions don’t stay in one place for long, while social media and AI have shortened the gap between discovering a narrative, spreading it, and exhausting it.
But a discarded theme bouncing back doesn’t mean it has reclaimed the center of the market. If earnings estimates keep rising and capital continues to flow in, it may still be a trending asset. If the move is driven mainly by short covering, an event, or a sudden spike in attention, it is probably still a trade.
SpaceX holding up despite a large lockup expiry may be another example. Maybe less stock was sold than expected. Or maybe the market had already moved past the unlock and started pricing in the next story.
In a market where narratives have shorter shelf lives, finding a good story is no longer enough. The harder question is whether it is still a trend, or whether it has already become just another trade.
