Below are a couple of cut and paste comments from Stockscores.com that we all need to be reminded of when it comes to the markets.

There are little tidbits of wisdom that I have picked up over my years as a trader, here is a list of some things that all traders should take to heart:

Don't apply logic to the stock market
So often I see people make decisions in the market on what makes sense to them. It makes sense to buy stocks when the company insiders are buying. It makes sense to buy stocks that are making positive announcements. It makes sense to listen to what the President has to say about the company's prospects. However, all that matters is what the market thinks of the company and whether the buyers are more motivated than the sellers. So often, the market does things that do not make any sense until we later learn of what motivated the market to do what it did. Remember, the market is forward looking, most times, what makes sense is judged on what has happened in the past.

People lie, markets don't
I have learned the hard way to never trust what people say, their actions say much more. Learn to read the market and understand it's message. No matter how much insight a person may have, recognize that they have a bias based on their own emotional attachment to money.

Publicly available information is priced in to the stock, don't rely on it to make decisions
Once information, no matter how good, is made public, it loses its usefulness to you. Public information is priced in to the stock by the market of investors. Information only has value to you if the market has not priced it in.

Successful investing is not about being right, it is about making money
Most good traders are usually wrong. They will lose small amounts often and make big amounts occasionally. What matters is how much they make over a large number of trades. Don't try to always be right, simply work to make money.
