NEW YORK, Nov 17 (Reuters) - U.S. stocks were near flat Monday afternoon as deal activity in the energy and healthcare sectors offset concerns about overseas growth after Japan's economy slipped into recession.

Weighing on the Nasdaq, which was underperforming both the Dow and S&P 500, were shares of Amazon, which fell 1.9 percent to $321.54, as well as Staples.
Energy shares dropped with crude futures after Japan's economy unexpectedly slipped into recession in the third quarter. The S&P energy index fell 0.3 percent.
