That's not necessarily true. From what I saw, and I watched all day long, only around 6m shares out of over 30m traded appeared to have been diluted by UBSS when they were on the ask. The rest of the day, almost all of the trading was retailers buying at the ask from various MMs. 30m in volume is very respectable and most of it was by retailers. All you would have had to do was to watch it tick by tick. Are buyers hesitant? Yes. But, obviously not to overwhelmingly worried.
