With https://fintel.io/so/us/poet as source it seems that almost all institutional sold their shares. My guess is that they were forced by the PP to do so. Maybe it was some kind of an automatic mechanism or they had a minimum share price.
Hope we get infos for the promised alternative path of revenue/money promised by suresh soon. That would hopefully allow them to buy back in.
Now we only institutional is Fidelity Nasdaq Composite Index Fund with a few shares - guess they bought in January.
