Good luck.Investors who think they can be successful stock pickers are about to get some sobering news from new academic research. The good news: Yes, buying one stock gives you better odds than buying a lottery ticket. The bad news: Those "better" odds are still much too awful to stake your future on. For starters, think about Treasurys TMUBMUSD10Y, -0.23% those boring, low-paying government securities that are at least reliable. Right now, you can buy a one-month T-Bill and expect a yield of about three-quarters of 1%. And you'll get your principal back.via
