Mumbai, June 14 (IANS): The Indian equity markets on Wednesday provisionally closed on a flat-to-positive note on the back of healthy wholesale price index (WPI) data and buying in capital goods, oil and gas as well as energy stocks.

Official data released during market hours showed that India's annual rate of inflation based on wholesale prices decelerated last month to 2.17 per cent from 3.85 per cent in April as food prices eased.

However, investors remained cautious ahead of the outcome of two-day US Federal Reserve's rate-setting meet later in the evening.

At 3.30 p.m., the wider 51-scrip Nifty of the National Stock Exchange (NSE) inched up 7.40 points or 0.08 per cent to provisionally close at 9,614.30 points.

The 30-scrip Sensitive Index (Sensex) of the BSE, which opened at 31,147.69 points, closed at 31,155.91 points -- up 52.42 points or 0.17 per cent from its previous close at 31,103.49 points.

The Sensex touched a high of 31,190.36 points and a low of 31,054.94 during intra-day trade.

The BSE market breadth was bearish -- with 1,418 declines and 1,249 advances.
