Remaining cautious before the beginning of the quarterly earnings season, the key Indian equity market indices on Thursday opened flat.

The Sensitive Index (Sensex) of the BSE, which had closed at 34,433.07 points on Wednesday, opened higher at 34,471.48 points.

Minutes into trading, it was quoting at 34,440.28 points, up by 7.21 points, or 0.02 per cent.

Two equity indices — Sensex and Nifty50 — slipped into red as investors turned cautious ahead of the start of the quarterly earnings result season on January 11.

According to market observers, broadly negative global cues and heavy selling pressure in consumer durables, auto and banking stocks added to the downward trajectory of the key indices.

In the day’s trade, the barometer 30-scrip sensitive index had touched a high of 34,565.63 points and a low of 34,311.63 points.
