I know that many people in the investing world like to take their shots at Jim Cramer, but I have been watching him for the past couple of weeks and he really knows his stuff.

I understand that some people don't like is hyperactive style, but beneath the showmanship and energy is a lot of knowledge about the investing world.

I tried to imagine the other day what it would be like to be on television for an hour taking random questions about random companies. His producer and the charts help him, but he often starts talking about a company as soon as a caller brings it up. I would need to stumble for a couple of seconds while glancing at the charts and my notes to figure out what to say. Not Jim Cramer, he is on the ball with good information.

I was really impressed when Cramer starting talking about a sector that I knew a lot about. He was right on with most of the information he was delivering. It was impressive and makes me more likely to trust his recommendations in sectors I don't know as much about.

I liked his advice to stick with what we know. We shouldn't be trying to invest in everything because each sector is a little different. We should invest in a certain sector and become an expert in it.

I plan to continue watching Jim Cramer's show. I wish there was more than just a couple investing programs and channels on television. Hopefully the internet will soon merge with our television sets so we can have more people creating more investing shows to help us understand what is going on.
