As of 22-Sep, Som Datt Finance Corporation Ltd is experiencing a price increase, currently at Rs 133.00, which reflects a rise of Rs 3.1 or 2.39%.

The stock reached an intraday high of Rs 134, although it also saw a low of Rs 125.1 during the day. Over the past week, the stock has increased by 10.28%, while its year-to-date return stands at 12.00%.

Broader Market Context: In comparison to the benchmark Sensex, which has only increased by 0.46% over the past week, Som Datt Finance's performance is significantly stronger. The stock's recent gains highlight its resilience, particularly given its impressive three-year return of 401.89% compared to the Sensex's 38.97%. Despite a slight decline of 4.66% over the past month, the stock's overall upward trend in the longer term, especially its 20.04% increase over the past year, suggests that it is maintaining a positive trajectory relative to the broader market.
