NEW YORK ( TheStreet) -- I featured three stocks on my radio show on Thursday. You can click here to listen to the show if you wish. I am going to highlight one of the stocks that I recently featured.It always amazes me how many simple, under-the-radar types of companies rise to the top in my ranking system. Most of the time they are stocks that have not been talked about on the financial channels. Most of the time, I have not read about them in the financial media. Yet, these stocks quietly produce terrific performance for their shareholders year after year. Today, we are going to travel to Calabasas, Calif. We are going to peek in on a $1.3 billion small-cap company that provides permanent and temporary IT, healthcare and lab support staffing to 5,347 clients via 76 offices in 24 states. I told you that it was a very simple little company. The name of the company is On Assignment ( ASGN). This has also been a very strong sector in the market. I also like Barrett Business Services ( BBSI) and Computer Task Group ( CTGX) in this space.
