The BSE Sensex ended 0.5 percent higher on Wednesday, helped by a rally in software stocks including Tata Consultancy Services (TCS.NS) and Infosys Technologies (INFY.NS) and gains in index heavyweight Reliance Industries (RELI.NS).

The main 30-share BSE index added 84.87 points to end at 17,707.32, with 22 of its components gaining. The index rose as much as 1 percent intraday and has gained more than 14 percent this year.

The benchmark's 14-day Relative Strength Index was at 71.9, above the 70 mark that indicates stocks are trading in the overbought zone.

Overbought markets can become much more overbought as long as liquidity is there.
