he Indian stock market has experienced significant volatility over the past year. Data from ACE Equity shows that the one-year return for the broader market benchmark, the BSE 500 index, remained almost flat. However, several stocks within the BSE 500 have experienced steep declines, falling as much as 64%. Here are some of the biggest losers over the past year:

Sun Pharma Advanced Research Company (SPARC) has emerged as the biggest loser among BSE 500 stocks, witnessing a 64% drop in its stock price. Its shares were trading at Rs 127 apiece, with a market capitalization (m-cap) of Rs 4,100 crore as of February 24, 2025. The company has been struggling with consistent losses, reporting a net loss of Rs 284 crore for the nine-month period (9M FY25) ending in December 2024, after a loss of Rs 281 crore in 9M FY24.

Network18 Media & Investments – Despite a turnaround in profitability, the stock of this media and entertainment sector company plunged 61% in a year. The company posted an impressive profit of Rs 3,282 crore in the first three quarters of FY25 (April to December 2024) after recording a loss of Rs 189 crore in the same period last year.

Adani Green Energy, one of the major renewable energy sector companies, suffered a 56% drop in its stock value. Its latest market capitalization stood at Rs 1.35 lakh crore, down from Rs 3.05 lakh crore a year ago. While it reported a profit of Rs 567 crore for 9M FY25 against a loss of Rs 351 crore in this duration previous year.

Sterling and Wilson Renewable Energy – This infrastructure sector stock has faced headwinds, declining 54% in price to Rs 267, with a market capitalization of Rs 6,230 crore. The company managed a turnaround from a Rs 2 crore loss in 9M FY24 to a Rs 226 crore profit in 9M FY25.

Mangalore Refinery and Petrochemicals, a public sector enterprise (PSU) in the crude oil sector, saw its stock decline by 53% to Rs 114, with a current market capitalization of Rs 20,000 crore. The company reported a loss of Rs 313 crore in the first three quarters of FY25 (9M FY25), compared to a Rs 2,459 crore profit in the previous year. The sharp fall in earnings likely led to the steep correction in its stock price.

Sonata Software & Tanla Platforms – These IT stocks also saw significant corrections, with both Sonata Software and Tanla Platforms falling 51%. While both companies posted profits of Rs 196 crore and Rs 115 crore respectively in the first three-quarters of FY25, an expected slowdown in global IT spending and valuation concerns may have contributed to the decline.
