T+1 Settlement and the Algorithmic Age: A New Era for Stock Valuation with Potential Market Froth

Significant participation on the stock exchange in India comes from Investors from other countries. Local institutional investors including mutual funds and corporate bodies also invest heavily in Indian stocks. Both FIIs and DIIs, the institutional investors nicknamed ‘elephants’ due to their significant financial strength. These key participants greatly influence how the stock market moves by the way they buy and sell. This research delves into the connection between large foreign, local players and gains in the stock markets over a 180-day timeframe. We analyze the potential impact of the recently introduced T+1 settlement phase on the Indian economy. The period between October 2022 and December 2022 represents the ‘pre-T+1’ phase, functioning under the previous T+2 settlement system. The timeframe following January 2023 marks the ‘T+1’ phase, reflecting the new settlement regulations. Data summarization, an enhanced Dickey-Fuller test, regression and correlation techniques could all be used in the study. According to the findings (considering a hypothetical scenario of T+1 settlement being implemented), the study would investigate whether the T+1 settlement phase has any significant effects on net purchase transactions undertaken by the large players. It would examine how sectoral indicators such as the Nifty 50 react to the introduction of T+1 settlement. The analysis would determine if the impact on the Nifty 50 Index Returns is significant and at what significance level. The study would assess how the T+1 settlement phase deepens its impact on sectoral indices except Nifty Public Sector Undertaking (PSU), Nifty Private Bank, and Nifty Reality (if the historical trends hold true). It would be interesting to see if the T+1 settlement disrupts any particular sector more than others. This research would help policymakers anticipate and mitigate the potential effects of the T+1 settlement phase on the market. By examining the impacts on different investor classes and sectoral indices, the study would provide valuable insights into how the market adjusts to this new settlement.
