Risk management is everything in this business. You can make all the money you can, but if you get hit by one of the many stocks that Herb red-flagged over the years, that stock can wipe out a huge amount of your profits. Herb's the first to admit that he can be wrong, another trait I will always love about him, but in my experience, he's a lot more right than he is wrong. And when the React-O-Meter goes spinning out of control, look out, you might be stepping on a real landmine. (If you don't know what the React-O-Meter is, go to Google. It's the first entry.) So, the most critical mind in the biz is back in the fold -- and we will still get to see him on CNBC. It's the best of both worlds, the way I see it. Herb's presence is our legitimacy once again. Ignore us at your own risk. You can't afford not to read Herb Greenberg. Welcome back, dear friend, you were sorely missed.
