I like to give my input.

If you have a sufficient amount of shares, where you will have a lifestyle change if ptsc runs up........don't buy anymore (IMO) until or unless something significant happens (ie uspto).

There is nothing wrong with chasing a stock on upward trend IMO.

If I had money to invest; there are just too many good companies/investment out there that have a depressed shareprice to not diversify.
