My list is always changing depending where a stock is at. If they are not at certain levels then I won't trade them. As far as fluctuation goes and what I'm currently trading, my stocks and ETF's are:
CBMX - Usually goes up big when it is floating around $3.00. It's a pump and dump stock so on the high volume day is when you get in and you sell before the day ends for 30% or more.
My stocks change all the time but NUGT, DUST, DGAZ and UGAZ has been big for me. I like to play the swings for very short periods. If I'm wrong I get out. I got other stocks that are pure calculated gambles like CLSN and I have a long position in FNMA but it's good for daytrading on certain days.
Yes I have been in fnma three times has been a great trade, Ive heard of dust and its counterpart dug. I will check out the rest. And I do the same if it falls to a point Im out and move on. Thanks for some more DD
