NEW YORK, Oct 13 (Reuters) - U.S. stocks were nearly flat in early afternoon trading on Monday but were off the lows of the session following the S&P 500's break below 1,900 and another key technical support level.
The index traded as low as 1,890.67 earlier in the session. It remained below its 200-day moving average of around 1,905.
Investors have been cautious ahead of earnings this week, one of the busiest weeks of the reporting period.
