MUMBAI (Reuters) - The BSE Sensex snapped a four-day winning streak on Monday, retreating from near 2-1/2-year highs as investors booked profits in rate-sensitive stocks such as ICICI Bank, while drugmakers were hit by worries about the country's new drug pricing policy.
Caution also prevailed after Standard & Poor's statement reiterating its "negative" outlook on India's sovereign ratings, which came out shortly before the close of markets on Friday.
Analysts said some consolidation was due for domestic markets after the benchmark BSE Sensex has rallied about 11 percent rally since mid-April due to strong foreign inflows.
Foreign investors have been net buyers for 22 consecutive sessions as of Friday, bringing in a net of about $13.52 billion in 2013, regulatory and exchange data shows.
"Market has had a straight run up for last few weeks due to liquidity, so some amount of correction is required," said Deven Choksey, managing director of KR Choksey Securities.

There are no signals so far that liquidity is abating so one can look to accumulate good stocks on declines, added Choksey.
