Hi Frank,
AD8 is best known for developing Dante, a leading digital audio networking technology. The stocks had a rollercoaster ride from around $5 in mid-2022, to over $23 in 1Q of 2024 before falling all the way back to $5.
The move over the last few weeks coincides with a significant reduction in the short positioning in AD8, which fell from around 4.5% of the free float to touch the 2% level – equating to ~3m shares being bought,  at the same time to stock popped ~40% up from $5, to trade above $7. In other words, it was a simple short-covering rally after the stocks awful 18-months and once this was complete as you say the stock has drifted back towards $5.
