Major U.S. stock-indexes mixed on Tuesday, weighed down by a 6% slump in Chinese shares and Wal-Mart's (WMT.N) weaker-than-expected quarterly results. Wal-Mart shares fell as much as 3.2% to a nearly 2-1/2 year low of $69.58 and were the biggest drag on the Dow Jones industrial average. Chinese stocks plunged again as the yuan weakened against the dollar, re-igniting fears that Beijing may be intent on a deeper devaluation of the currency despite the central bank's reassurances.

Most of Dow stocks in negative area (17 of 30). Top looser - Wal-Mart Stores Inc. (WMT, -3.12%). Top gainer - The Home Depot, Inc. (HD, +3.26).

Almost all of S&P index sectors also in negative area. Top looser - Conglomerates (-0.8%). Top gainer - Healthcare (+0,3%).
