NEW YORK, Nov 12 (Reuters) - The Dow and the S&P 500 indexes were flat to slightly lower on Thursday, threatening to snap a six-session rally for the Dow, after a Wal-Mart Stores Inc forecast sparked concerns about consumer spending.

The Nasdaq gained, however, lifted by Intel Corp (INTC.O: Quote, Profile, Research) and Advanced Micro Devices Inc (AMD.N: Quote, Profile, Research) after the chip makers said they settled all outstanding legal disputes, including antitrust litigation and patent-licensing issues.

"Despite the fact that Wal-Mart tends to give conservative guidance, expectations have risen so much," said Burt White, managing director and chief investment officer at LPL Financial in Boston. "Wal-Mart's tepid outlook is weighing on consumer sentiment and making people rethink (about the market rally)."
