The key indices of the Indian equities market provisionally closed on a flat note on Friday.

However, the two key indices -- the S&P BSE Sensex and NSE Nifty50 -- had made record new intra-day highs during the early part of the day's trade.

According to market observers, expectations of healthy quarterly results and buying support for the auto and banking stocks had lifted the key indices.

On intra-day record high basis, the barometer 30-scrip Sensitive Index (Sensex) of the BSE touched 33,286.51 points, while broader 50-scrip Nifty at the National Stock Exchange (NSE) reached 10,366.15 points.

At 3.30 p.m., the NSE Nifty 50 slipped by 21 points or 0.20 per cent at 10,323.05 points.

The Sensex of the BSE, which opened at 33,228.32 points, provisionally closed at 33,157.22 points (at 3.30 p.m.), higher by 10.09 points or 0.03 per cent from Thursday's close at 33,147.13 points.

The Sensex had touched a high of 33,286.51 points and a low of 33,164.42 points during the intra-day trade.
