The last 3 days AEYE has had its closing transaction take the stock to the high for the day. Years ago I would have called this manipulation. I don’t know if that is still possible today, maybe you can with a stock as small as AEYE. I don’t know what to make or think of it.
I would suspect it is someone building a large position up. Buying near the close prevents unnecessary intraday spikes, and might help keep the over all cost down. No need to don your tinfoil hat quite yet, I think.
