there's a guy on the o'reilly factor right now, daniel solin, who says the "big secret" is that it is "mathematically impossible" to beat indexes over a 10 year period. he is the author of the book, "does your broker owe you money?" o'reilly was like, "so there's nothing you can do?" the guy said, "statistically." solin also said someone won the nobel prize for this discovery. i'm not saying i agree with this, but i figured i'd post it here.
