Micron and SanDisk held billions more in hedge-fund capital in Q2 2026.
Yet hedge funds held fewer shares. So who was buying, who was trimming, and how crowded did the trade become?
At the end of June, five hedge funds held nearly half of all hedge fund reported SanDisk. In July, SanDisk fell 47%.
By now you’ve seen the Situational Awareness story. But one fund’s leverage isn’t the lesson for allocators. Crowding is.
We compared Q1 vs. Q2 2026 13Fs for Micron (MU) and SanDisk (SNDK). In both names, reported value more than doubled while hedge funds held fewer shares. Most managers trimmed. A few sized up hard. In SanDisk, the top five holders went from 33% to 48% of reported hedge-fund holdings in a single quarter.
And the crowding wasn’t confined to one ticker. Hudson Bay exited Micron and opened a $696M SanDisk position the same quarter. Arrowstreet and D.E. Shaw cut Micron but sat in SanDisk’s top five. On a ticker screen, that looks like de-risking. On a theme screen, the memory exposure was still there.
When ownership is that concentrated, the exit gets narrow fast.
For allocators, the question isn’t whether memory was a good trade. It’s how many of your managers were in it together. A tech specialist, a growth fund, a quant and a multi-strat can look like four return streams and still share the same two stocks, and the same exit.
On Radient, you can go from security → institutional ownership → your manager universe → portfolio overlap → crowding, and see where your lineup overlaps before the next drawdown.
The number of managers you own isn’t the same as diversification.
