Mumbai, Oct 20 Key Indian stock market indices opened marginally higher and were trading flat in the early hours of the session on Tuesday, in line with the Asian peers.

 
The sensitive index (Sensex) of the Bombay Stock Exchange (BSE) opened 37.98 points higher at 27,402.90 points, against the previous day's close at 27,364.92 points. But after 15 minutes of trading, it was ruling flat at 27,366.21 points, up merely 1.29 points.
 
At the National Stock Exchange (NSE), the Nifty was also ruling flat at 8,270.60 points, albeit with a marginal loss of 4.45 points, or 0.05 percent.
 
The two major indices had gained a little over 0.5 percent on Monday, on account of some better-than-expected corporate results for the second quarter of this financial year, notably the 12.5 percent jump in the net profit of market leader Reliance Industries.
