I think many have misinterpreted Jack's dream, he's saying $3 now and be done with it. I'd gladly sell for $2 tomorrow.
Besides the usual arguments about risk, here's the other thing to consider - if the stock were to organically run to, say, $3, how many of the shares you own now would you still own?
Let's say a guy has 100,000 shares to make it a nice round number. I guarantee you that most such guys would not hold 100,000 shares at $3. Myself, I'm sure I'd sell some at (US$) .60, .80, 1.00, $1.40, $2.00 or some such. And I think many others would do something similar. So, by the time $3 rolls around, today's 100,000 shares might look more like 15,000-25,000. So, let's say a guy sold 80,000 shares on the way up to $3, for an average of $1.25, that's $100,000. Now, he holds 20,000 and eventually gets bought out or sells out at $10, so that's another $200,000, so that's $300,000 total, which is the same as you would have gotten if you sold tomorrow for $3, and no more risk, frustration, etc.
I did not preplan those numbers, they just happened to work out that way as I typed, and I'm glad they did, as I could see the above as a scenario.
If you're adamant that you would sell no shares on the way up, then I believe you're fooling yourself, or you really don't need the money, in which case playing POET stock is very appropriate for you!
