Heavyweight sectors banking and IT together constitute 41 per cent of Nifty50 and 31 per cent of NSE-500 weights to date.
Further, the average divergence between both indices stood at 37 per cent over 2012-2022, highlighting the obvious but critical role of sector selection in alpha creation, the brokerage said.
The brokerage also highlights how the relative divergence between these two sectors – banks and IT – has played an important role in determining the relative out/underperformance of the Indian stock market.

Analysing the yearly performances of key sectoral indices over the last 10 years, Motilal Oswal said that Nifty-50 with other key indices posted a healthy double-digit growth during CY12-22.
