Mumbai: The BSE Sensex fell 65 points for the eighth session in a row on Wednesday to close at 18,469 as investors continued to offload stocks in view of RBI's hiking key rates and projecting lower GDP growth for this fiscal.

The 30-share Bombay Stock Exchange index, Sensex, which lost 1,068 points in the last seven sessions, fell another 65.33 points to close at 18,469.36.

However, gains in the most-heaviest Reliance Industries saved it from a bigger loss.

The gauge remained volatile throughout the session moved between 18,604.36 and 18,339.53.

Similarly, the broad-based National Stock Exchange index Nifty fell 28.10 points to 5,537.15 as stocks of auto, IT, metal and healthcare suffered heavy losses amid a weak Asian trend and lower openings in Europe.

The Reserve Bank on Tuesday raised lending (repo) rate by 50 basis points to tame inflation and projected 8 per cent economic growth for this fiscal, as against the government's forecast of 9 per cent.

RBI also hinted at further tightening, saying that inflation is likely to stay at ‘elevated levels’ until September and it would give priority to taming the rate of price rise.

However, a firming trend in the oil and gas sector, led by Reliance Industries, saved the market from a major fall. RIL stocks, with nearly 13 per cent weightage on the Sensex, gained 0.32 per cent to Rs 947.
