This is a good illustration of one of the dangers of low float stocks. It dropped today on no news. Earnings is coming on Monday, and I think a lot of people have been buying in anticipation. I took a look at a one minute chart to see if it gave any clues. Although I don't know for sure, it could have been manipulation by short sellers (or a hedge fund) to trigger stops and scare holders into selling so they could pick up cheap shares. I posted the times and the amounts of the drops on the chart. It did not drop all at once, there were 3 time intervals where the drops took place. Is this a good buy here? Maybe, but I wouldn't touch it until after earnings are out. There is also a possiblity that bad news leaked out (illegal but it happens).
