Indian stock indices opened higher and reached record levels, with the Nifty breaching 6,700 for the first time. However, both indices pared some gains later in the day as investors took profits. The markets were supported by a stronger rupee and gains in global markets. Key banking stocks rose after the RBI extended a deadline for implementing capital rules. Specific stocks like Lakshmi Vilas Bank and India Cements rose on corporate news. Most sectors ended higher, with power and real estate among the top performers.
