They got FDA approval, I sold just about all I had left yesterday and today in the $24-25 range. I'm keeping a few shares keeping in mind the buyout possibility. http://quotes.morningstar.com/stock/tkmr/s?t=tkmr
Making a big investment in any stocks, in my opinion, will be a big mistake; it's no different than when a [wo]man got out of a bad relationship and the last thing he/she should do is get into another relationship with another [wo]man immediately afterwards. It's best to research and see, which companies are stable enough now and have less risk of failing in the near future, and then invest in the stocks you believe should be beneficial; I stay away from tech companies, unless you can afford a lot of insurance, bonds, or other means to substantiate the possible losses, you may experience with such businesses.
I haven't made any big investments recently just because of the unstable markets. It is hard to know which one will rise and which one goes down. In these times I prefer smaller investments in stable and trusted corporations.
Sold off half of my 1000+ share stake in NUAN today. Starting buying this one a couple of years ago when it was some 30% cheaper. Realized a nice profit here today. http://www.marketwatch.com/investing/stock/NUAN
