That´s the problem with evolving companies. When is the right time to jump in?

If you discovered a company you are convinced to go boom, would you want to miss this moment? I do not think POET will need two years, good things may also happen in two months. But what do I know. Make your own bet.

I bought my first POET shares in 2015 so call me newbie :-)  The last months were the most exciting months of the last seven years. POET accelerates. If these news don´t make you wait and hold for a bit longer I don´t know what can do the trick.
