Stock indexes: The five-day and three-month Dow charts in the Daily Market Roundup of some editions of the Jan. 1 Business section showed data from the end of trading Dec. 30 instead of Dec. 31. The Dow on Dec. 31 climbed 7.80 points to 11,577.51. In the same editions, the arrows next to the percentage changes in the S&P 500 and the Nasdaq were pointing up, incorrectly indicating that those indexes rose Dec. 31. Separately, at the top of all editions of the Jan. 1 Business section, the quote for the euro indicated it rose $0.02. It actually rose $0.008.
