Market recap: Stocks closed out their strongest January in 15 years on a tepid note after a series of disappointing economic reports (I, II, III). Yet stocks crawled back from early losses, repeating the frequent pattern of recent days. Financials were boosted by optimism from Europe, but Exxon's mediocre Q4 hurt energy shares. Treasury yields neared four-month lows. NYSE winners led losers seven to six.
