Patience vs. Panic
Investing is all about putting money into a stock based on your thesis of the company. When the story changes then your original thesis must change also.
Ask yourself: Did anything material about the company change since the last purchase you made?
You can't let the day to day changes in pps be a factor in the way you view the company. B/c on the pinks, one or 2 good days easily can make up for 20-30 crappy consecutive days.
I've been here since Feb 12th. Pull up the chart and figure out when I got in and notice how bad things sucked pps wise for a couple months. Now I look like a genious. Not only did my thesis on TYTN remain the same from Feb 12th, it actually increased--unlike the pps.
If you want a good example of somone that lost out in tens of thousands of dollars b/c of impatience (actually more like around $120,000) click on the 'view posters' icon and look at the top poster on this board. He claimed to have over 32MM shares that were mostly bought in mid-Feb in the 10-12 range.
Whatever he's done since has not made up for the gains he lost out here.
This is entirely your call. IMO, it's too much of a risk selling at these levels vs. what Mark Leonard has in store but that's only b/c I've done as much DD on this company that I can possibly do. Things might steadily trickle downward to the 20's even, but once another big deal is announced we can easily double the next day and make up for all the day-to-day nonsense.
