As 2025 nears its end, the Indian stock market has seen significant shifts, leaving over 300 stocks within the BSE 500

index trading with losses. Several companies have experienced dramatic drops in value, with some stocks plummeting as

much as 70% throughout the year.

Market volatility, rapid changes across different sectors, and evolving investor preferences have created sustained

pressure on numerous stocks. Here's a look at ten of the BSE 500's poorest performers that have become the year's

biggest underachievers.

**Top Losers of 2025**

* **Aditya Birla Fashion:** Shares of this Aditya Birla Group company have suffered the most significant decline on the

index in 2025, falling by 73%, according to data from ACE Equity. Despite this, the company's net profit for the

September quarter of FY'26 increased to Rs 295 crore. Revenue from operations for the same period reached Rs 1,981.66

crore, up from Rs 1,760.51 crore in the corresponding period last year.

* **HFCL:** This company, which specializes in optical and broadband wiring, has experienced a year to forget, with its

stock price dropping by more than 62% year-to-date. However, there was some positive news: earlier in the week, HFCL

secured contracts to supply IP routing equipment for seven of the twelve BharatNet Phase III packages awarded thus far,

positioning it as the primary supplier for this government rural broadband initiative.

* **Ola Electric:** The stock price of this electric two-wheeler manufacturer has decreased by 61.6% in 2025. The stock

is currently trading around Rs 31, a considerable decrease from its peak of Rs 157 per share. The company's consolidated

net loss for the second quarter narrowed to Rs 418 crore, compared to a loss of Rs 495 crore in the same quarter of the

previous year.

* **Motherson Sumi Wiring India:** This auto ancillary company has witnessed a 60% decline in its stock price since the

start of the year. Foreign institutional investors (FIIs) have been gradually reducing their holdings in the company

over the past few quarters, decreasing their stake from 8.32% in December 2024 to 6.98% by September 2025, indicating a

decrease in overseas institutional ownership.

* **Persistent Systems:** After delivering returns of over 200% in 5 years, this multibagger stock has plummeted 59.51%

in 2025. The company's shares are on track for their worst calendar year performance since 2008, when they fell by 73%.

* **IRB Infrastructure Developers:** This infrastructure company's stock price has slipped 58% in 2025. Earlier in the

week, the company received an income tax demand of Rs 72.03 crore, which included Rs 42.33 crore in interest, for the

assessment year 2007-08.

* **Brainbees Solutions (FirstCry):** Shares of FirstCry, India’s largest multi-channel retailer for mother, baby, and

kids' products, have fallen 55.4% this year. The company reduced its consolidated net loss by 20% to Rs 50.5 crore in

the second quarter, while its revenue increased by 10% to Rs 2,099 crore.

* **Paytm:** Shares of Paytm have also declined 55% this year. During the second quarter, the company reported a net

loss of Rs 473 crore, a stark contrast to the net profit of Rs 7 crore reported in the same quarter of the previous

year. However, revenue increased by almost 70% year-on-year to Rs 1,748 crore.

* **JB Chemicals & Pharmaceuticals:** The stock is down 53.77% in 2025. In the September quarter, the company reported a

sharp 52% year-on-year decrease in net profit, falling to Rs 66.4 crore, while revenue decreased by 8% to Rs 555 crore.

Management cited deferred shipments at its CDMO and FDF facilities as the reason for the revenue decline.
