The Dow was flat on Monday, securing its third-straight win despite a volatile final hour of trading. The Nasdaq and S&P 500 snapped their two-day win streaks, however, with the former turning in significant losses as the tech sector struggled. Investors appear to be brushing off a strong earnings season, in which 76% of S&P 500 names have so far beat revenue estimates.

All eyes are now on Thursday's inflation report. Investors still have plenty of earnings to unpack before then, though, with reports from Walt Disney (DIS) and Coca-Cola (KO) on deck, while Take-Two Interactive (TTWO) just stepped into the earnings confessional.

The Dow Jones Average (DJI - 35,091.13) added 1.4 points or was flat for the day. Boeing (BA) led the gainers today with a 2.7% pop, while Microsoft (MSFT) paced the laggards with a 1.6% drop.

The S&P 500 Index (SPX - 4,483.87) fell 16.7 points or 0.4% for the day. Meanwhile, the Nasdaq Composite (IXIC - 14,015.67) shaved 82.3 points, or 0.6% for today's session.

Lastly, the Cboe Volatility Index (VIX - 22.86) shed 0.4 points or 1.6% for the day.

OIL PRICES DIP AMID U.S.-IRAN NUCLEAR DEAL TALKS

Oil prices were lower on Monday, amid reports that the U.S. and Iran seem to be making progress towards a nuclear deal, after the White House waived sanctions on some of Iran's civilian nuclear activities. March-dated crude fell 99 cents, or 1.1%, to settle at $91.32 per barrel for the day.

Meanwhile, Gold prices notched their best session in roughly three weeks. The yellow metal's pop came about amid swirling inflation concerns, as the Federal Reserve plans this year's interest rate hikes. In response, April-dated gold added $14, or 0.8%, to close at $1,821.80 per ounce.
