Some people would have had to close their trade within 3 days as well, as it was such low volume towards end of session, that certainly is an option here.

It does indeed smell like a rally. We are owed one for the latest battery update, which addressed the cycle life problem.
This should have made this stock fly as our MTA partners would step up negotiations a notch now. Commercial discussions with partners expected by mid year, half cell battery evaluation from first collaborator by early April, this is news to the market.
Market has not yet appreciated this, that should start tomorrow.
Pressure should be building from here on, in my humble opinion.
