I wouldn't read too much into the price action. The lows have been put in and we've had a technical rebound above the $2.40 resistance area which should now act as support if this pps rally has legs.

From a technical analysis perspective (and I'd be happy to post a chart with commentary if I could figure out how):

MNKD has broken out of an area of consolidation. It closed above the 50 day moving average. There was bullish RSI divergence at the lows and this move has confirmed that oversold indication. There was a positive MACD cross and MACD is now sloping nicely upwards.
