In "Grumpy Old Permabear," I noted that "a growing number of commentators are suggesting that the worst is behind us," and included (among others) a link to a post by Calculated Risk, "The Housing Bottom is Here." While I certainly can't say for sure that Bill McBride is wrong (FWIW, I am a big fan of CR and have been a regular visitor since its earliest days), I did point out that "genuine bottoms have, historically at least, gone unrecognized until well after their arrival."
On the flipside, long, secular downturns -- like those that invariably follow bursting bubbles -- are littered with endless claims of a recovery being at hand. As it happens, Weakonomics has compiled an extensive collection of such pronouncements about the current bear market, stretching back almost six years, in "The Megalist of Calling the Housing Bottom." Here are some examples:

Otherwise, it's been a while since I last highlighted a chart like the one that follows (the unedited original comes via Business Insider), but I thought it might be something worth noting to those who believe the Fed actually knows what it takes to look after or "fix" the economy (or whatever else Bernanke & Co. claim they are responsible for):
