US stock futures and global markets head lower

NEW YORK (AP) — Stock futures are falling after major U.S. averages again tested record highs to start the week.

Despite questions about whether markets have gone too far, the Dow Jones industrial average rose above 16,000 for the first time Monday.

Dow Jones industrial futures are down 3 points to 15,935. S&P futures have lost 3.4 points to 1,785.20. Nasdaq futures are down 3.25 points to 3,380.50.

A mixed read on the consumer emerged Tuesday, as Home Depot continued to ride the recovering real estate market to better-than-expected earnings. And while Best Buy topped Wall Street expectations as well, shares are falling sharply after the retailer warned that margins will be under pressure as it fights off online competition with a marketing blitz.

Campbell Soup missed badly on its quarterly profit.
