They're generally for the more advanced, meaning people who manage their own portfolios. Most people who just have a stock manager don't end up involved with them but I'd say more like 50% of people who manage all their own shyt buy them. fukk puts though, what I'm telling you RIGHT NOW is ticker SPXL not slowing down before it hits $90 a share check its history. It just did its yearly September/October dip and it's about to be caaaashout time. Dropped to 80 I predict it hitting 102. Last year I copped at 65 and sold at 83.
