March 15 (Reuters) - U.S. market index compiler MSCI Inc said it was not in talks for a possible takeover.
"We have not received any offer or indication of interest," the company said on Wednesday.
The company's response came after a media report that financial data provider S&P Global Inc was seeking to buy MSCI for $11 billion.
MSCI's shares trimmed most of their gains and were up 1 percent. They had risen as much as 13.5 percent to a record high $109.29 in early trading.
Shares of S&P Global were down 1.3 percent at $130.50. (Reporting by Diptendu Lahiri in Bengaluru; Editing by Sai Sachin Ravikumar)
