The Indian equity markets displayed robust positive sentiment last week, resulting in a significant surge in the market capitalisation of the nation's leading firms. Nine out of India’s ten most-valued companies collectively added a substantial Rs 1,00,850.96 crore to their market valuation. This upward trend was further underscored by the benchmark BSE Sensex, which climbed 737.98 points, or 0.90%, during the week, contributing to the healthy growth in the market worth of these major corporations.

Leading this impressive rally were two of India's corporate giants, Reliance Industries and HDFC Bank, which recorded the most substantial increases in market capitalisation, reflecting strong investor confidence. Reliance Industries emerged as the top gainer, with its market valuation increasing by Rs 30,786.38 crore, bringing its total market capitalisation to a formidable Rs 19,53,480.09 crore. Following closely, HDFC Bank also saw a significant boost, adding Rs 26,668.23 crore to its valuation, which consequently rose to Rs 15,15,853.85 crore.

Several other prominent companies within the top-ten echelon also contributed to this positive trend. Bajaj Finance registered a notable gain of Rs 12,322.96 crore, elevating its market capitalisation to Rs 5,82,469.45 crore. ICICI Bank was another key gainer, with its market worth increasing by Rs 9,790.87 crore, taking its total valuation to Rs 10,41,053.07 crore. Hindustan Unilever also performed well, adding Rs 9,280.89 crore to its market cap, which stood at Rs 5,61,282.11 crore by the end of the week.

The list of gainers continued with Bharti Airtel, which saw its market capitalisation rise by Rs 7,127.63 crore, reaching a total of Rs 10,65,894.55 crore. The Life Insurance Corporation of India (LIC) also experienced positive movement, with an increase of Rs 3,953.12 crore, bringing its valuation to Rs 6,07,073.28 crore. Infosys made a modest gain, adding Rs 519.27 crore to its market cap, which settled at Rs 6,49,739.73 crore. Lastly, the State Bank of India also contributed to the gains, with its market valuation increasing by Rs 401.61 crore to reach Rs 7,25,437.74 crore.

In contrast to the widespread gains, Tata Consultancy Services (TCS) was the sole company among the top-ten most-valued firms to experience a decline in its market capitalisation. TCS shed Rs 28,510.53 crore from its market valuation, resulting in its current market cap standing at Rs 12,24,975.89 crore. Despite this reduction, TCS managed to retain its prominent position as the third most-valued Indian company, trailing only Reliance Industries and HDFC Bank.

Following the week's fluctuations, the hierarchy of India's most-valued firms saw Reliance Industries firmly at the top, followed by HDFC Bank. Tata Consultancy Services held the third position. The subsequent rankings were occupied by Bharti Airtel, then ICICI Bank, State Bank of India, Infosys, Life Insurance Corporation of India (LIC), Bajaj Finance, and Hindustan Unilever, completing the top ten list.

Market analysts and observers attribute these significant gains in market capitalisation primarily to the strong and positive investor sentiments prevailing in the market. This optimism is believed to be fueled by anticipation of key economic data releases and favorable global cues, suggesting a continued confident outlook among investors towards the Indian market.
