Move appears technical in nature. With short float @ 24M and ≈25% float, 24 days to cover it doesn't take much to induce a short squeeze, which I am assuming someone looked at the chart seeing the MACD was positioned where it was on weekly and that the 50 and 200 DMA had golden cross and took advantage of it. I wouldn't go long on this company due to their balance sheet, but if you're a trader that's risk adverse you could play it.
