The Sensex closed at 27,251, up by 374 points and the Nifty ended at at 8,235, up 109 points.
Benchmark indices have closed firm, amid volatile trading session, supported by strong buying among rate-sensitive sectors mainly financials and auto as the further softening in retail inflation to a four-month low of 4.87% in April gave rise to hopes of a rate-cut by the RBI.

Adds Kunal Bothra, Head - Advisory, LKP Securities, "The bi-directional volatility in the market, generally is an indication that the short term supports are in place. We believe that with Bank Nifty also doing well over the last few days, it augurs well for the benchmark index.
Technically, if Nifty breaks 8,350 then it could complete an Inverse Head and Shoulder pattern, which could trigger the next rally.
Hence, this level of 8,350 would now be a very crucial resistance for the index."
