Indian shares extended losses to a fifth session on Monday, dragged down by index heavyweight Reliance Industries and financials as investors sold off recent high-flying stocks.Equities in India rose sharply in the first two weeks of February, driven by solid corporate earnings, a well-received federal budget and strong foreign fund inflows.

''The market failed to show resilience to stay above the Nifty 50 Index level of 14,750. While it is subject to further price action evolution, the technical factors shifted today to support a further correction in the future,'' said Ashis Biswas, Head of Technical Research at CapitalVia Global Research Limited.

Biswas further said any corrective wave down should find support around 14,500-14,300.

''Traders are refraining from building a new buying position until we witness a correction till 14,300-14,500 level. The volatility is observed to expand in today's trading session indicating profit booking and stock distribution at a higher market level,'' he noted.
