這是我理解的炒股定義

My understand of '炒股' is day trading and quick turn over of stocks.  Saying 1% to 5% day traders making money is too generous.  Actually, only less than 1% day traders make money.  The rest of them usually disappear in about 2 to 3 years since it is very hard to make money consistently for a long period.  Day trading can produce profit in a short period of time when the market is up like right now.  

Remember 1999?  Everyone was a trader and everything you bought was going up.  Then, what happened?  No one is talking about anymore.  Remember 2005, everyone was a landlord or a mortgage broker, then they disappeared.  Now again, everyone is a trader again.  Let's good time roll!  But it won't be long.  For the last 50 years, all recessions have happened during the Republican presidents, never during the Democratic presidents.  Watch out!

I would suggest anyone who wants to be an investor, not a trader to read Benjamin Graham's 'The Intelligent Investor' and 'The Warren Buffett Way'.  These books will help you understand how to invest.  Good luck.
