Maybe someone with some money saw a great opportunity to do a short squeeze. That isn't market manipulation, it's a trading opportunity. No one is forcing anyone to short the stock. Do so at your own risk.
People make up their own rules when playing the trading game. Yours is probably that stocks should trade on fundamentals. When it doesn't do what you want it to you cry foul. Well, if it's one thing I learned during the internet bubble (losing thousands shorting AMZN) is to not fight the trend.
This is going to keep going higher the more people short it due to the low float.
You better understand that any insider can dump shares without the usual SEC filing notifying the public they're selling. Insiders can contribute their stock to an exchage fund.....the only notice filed with the SEC is a "non market disposition." Also insiders for a price can purchase a derivative that effectively hedges and locks in a price without actually selling the stock. Some of these practices were discussed in yesterdays WSJ.
