Trading
Some people trade successfully. I would have liked to sell short an oil contract if I'd had the $ to put up, since to me it seemed logical the price would've gone down once the public got word the oil rigs were going to come back online, and that the price was at an all time high. No-brainer trades like this, maybe 1,2 or 3 times a year.
Before that I would've sold a USDollar contract. Warren Buffett and George Soros were both short about a year ago and I wanted to ride their coattails. Now the dollar is showing signs of a possible turnaround...
Also, I have known people to day trade / swing trade (in the market a few days) but they only trade ONE stock they have some intimate knowledge of, such as price behavior certain times of the day, certain days of the week, or in response to news (price overshoots it's value in the morning in the publics wild overreaction to related news, then comes back to where it "should' be).
I traded about 8 years ago and had some success. I have been reading a lot too.
I have 30-40 books that are related to trading, and if I were to recommend my two favorites they are without question "The Disciplined Trader" by Mark Douglas

They look at the covers of major magazines at the newsstand to decide what to trade. It's amazing, the public PERCEPTION is a large force in the markets, as is greed and fear.
