The takeaway

🟢Bullish lean

The combination of heavyweight fund backing and an AI compute angle makes Aehr worth watching closely — the key question is whether demand for its chip-testing equipment keeps pace with the broader semiconductor boom.

But watch out
Smart-money signals lag the market (13F filings ~45 days) and never guarantee direction — always check the latest price and news yourself.
