BENGALURU, Sept 24 (Reuters) -

Indian shares opened relatively flat on Tuesday, holding

steady at record highs as traders paused following a record

rally spurred by the U.S. Federal Reserve's substantial interest

rate cut last week.

The benchmark Nifty 50 and S&P BSE Sensex

were down about 0.1% each as of 9:25 a.m. IST.

The indexes have scaled all-time peaks for three straight

sessions after the Fed cut rates by 50 basis points on Sept. 18.

"Markets are taking a breather after a recent surge in

Nifty, however the tone is likely to remain positive," said

Religare Broking's Ajit Mishra.

While seven of the 13 major sectors logged gains, commodity

indexes - Nifty metal and Nifty energy

-rose 1.7% and 0.4%, respectively. They emerged as biggest

gainers among the sub-indexes.

Asian shares rose as China's top financial regulators

rolled-out a slew of measures, saying it would cut bank reserves

by 50 basis points while reducing mortgage rates to try to spur

sluggish economic growth.

"China stimulus will be favorable for commodity

product companies," said Samrat Dasgupta, CEO at Esquire Capital

Investment Advisors.

A slow Chinese economy results in dumping of metals and

other commodity products in global markets, affecting local

economies, Esquire Capital's Dasgupta added.
