Interactive Brokers was the top seller for the day. It's unclear whether this was the buyer from 28th of February or a previous client who entered earlier, when the share price was in the mid 30s. Interactive Brokers had a net volume of roughly +261,000 shares prior to the 28th, so it's possible that someone who was sitting on a profit decided to sell. The average purchase price for the buyer on 28th of February was 58.6c, so it would be unlikely for them to sell at 55c, especially after the recent spike to the high 70s.
