Direxion unveiled their 3X ETFs last week. These things move at three times the price of underlying stocks. Gotta tell ya its a rush. BGU is 3X Bull large cap. BGZ is 3X Bear large cap. TNS is 3X Bull small cap. TZA is 3X Bear small cap.
The bids and offers change faster than a slot machine. The idea, I guess, is to place your “bet” where you expect the price to be in a minute or two and let the market come to you. But you had best have a firm conviction of market direction. Market orders get slaughtered.
I bought a small odd lot of TZA which was stopped out in minutes.
