We can't really say that any individual point in time is "the" bottom, but it's obvious just looking at pricing data that we are at "a" bottom. The S&P 500 is down where it was about 3 years ago, and the Dow is similarly situated. If you buy primarily indices, this drop is a bit like time travelling 3 years in the past to buy. And, it's hard to argue that that's not a better deal than buying, say, in December.
