Mumbai, Sept. 10 -- Indian stock markets continued their upward momentum on Wednesday, supported by positive global cues and the ongoing exchange of optimistic posts on social media between Prime Minister Narendra Modi and U.S. President Donald Trump.

The benchmark indices opened with strong gains. The Nifty 50 index started the day at 24,991, up by 122.40 points or 0.49 per cent. Similarly, the BSE Sensex opened at 81,504.36, registering an increase of 403.04 points or 0.50 per cent.

Experts noted that while the positive developments on the trade deal front are encouraging, the markets are still struggling with high valuations. Sustained earnings growth will be critical to support a stable rally.
