Disagree with a 7 year hold. This will double or triple from here before the next FDA ruling depending on the financing picture. Look at the recent biotech movers preapproval, especially in the high market stocks like Obesity. I scooped up Vivus at $8 when it was left for dead. My brother bought ARNA in the $1's (despite my trying to convince him he bought the wrong stock...we both sold recently and won big). Several others followed suit. MNKD will follow a similar pattern so long as they resolve financing and make the submission to the FDA. I'm nibbling at a few thousand more now... buying heavily upon financing picture being resolved up to $3.
The only difference with MNKD is I might want to (vs have to) continue holding for 7 years or more though because of the long term potential.
