It's true, wall street is a BIG casino. Good news, market crash ! Bad news, market Rally ! After you buy the stock, it decline. After you sell it, it go up. Every trader & investor has this kind of experience, Right ?
One said, " Don't predict the market, React with the market ". If the mkt going up - LONG (UPRO), if the mkt going down - SHORT (SPXU) ! That's a very simple & effective strategy. Of course, you must be very discipline to do that. Don't do the opposite, otherwise, you will get killed.
