7 Stocks That Witnessed Massive One-Day Crashes
Stock markets can witness sharp one-day declines when major regulatory actions, corporate developments, financial stress, or unexpected announcements trigger a sudden wave of selling. Over the years, several Indian stocks have recorded exceptionally steep single-day falls, wiping out significant market value within hours.
From Yes Bank and PC Jeweller to Adani Enterprises, Zee Entertainment, IEX and PB Fintech, these episodes highlight how quickly investor sentiment can change when a major event affects a company’s financial position, business outlook or perceived risks.
Here are the stocks ot look out for:
Yes Bank Ltd
Yes Bank Ltd is a private sector bank in India offering a range of banking and financial services to retail, MSME, and corporate customers. Its portfolio includes deposits, loans, digital banking, transaction banking, investment banking, and other financial solutions.
On March 6th 2020, Yes Bank witnessed an unprecedented collapse in its stock price by more than 80% in a single trading session after the RBI superseded its board and imposed a moratorium on the bank. Customers were also restricted to withdrawing a maximum of Rs. 50,000, intensifying concerns over the bank’s liquidity and financial stability.

The extraordinary regulatory action triggered a sharp sell-off as investors rushed to exit the stock amid heightened uncertainty. The company lost more than $1 billion in market value, although the stock later staged some recovery and still ended March 6, 2020, nearly 50% lower.
PC Jeweller Ltd
PC Jeweller Ltd is an Indian jewellery company engaged in the design, manufacture, and retail sale of gold, diamond, and other jewellery products. It operates through a network of retail stores and offers jewellery across wedding, everyday, and occasion-focused categories.
On February 2, 2018, PC Jeweller’s shares witnessed a sharp sell-off, falling nearly 55% intraday before recovering partially and closing around 25% lower. The sudden decline was triggered by market concerns surrounding Vakrangee, which had recently acquired a stake in the jewellery company.
Investor sentiment weakened further amid reports of scrutiny and alleged irregularities involving Vakrangee’s stock activity. The uncertainty prompted heavy selling in PC Jeweller shares, while the company clarified that its promoters had neither sold nor pledged their shares and that it had no business arrangement with Vakrangee.
Sammaan Capital Ltd
Sammaan Capital Ltd, formerly known as Indiabulls Housing Finance Ltd, is an Indian housing finance company focused on providing home loans and loans against property. It primarily serves self-employed individuals and customers in the affordable and underserved housing segments across India.
The September 21, 2018, crash of nearly 34% intraday in Indiabulls Housing Finance was largely part of the broader NBFC sell-off triggered by the IL&FS crisis. Defaults by IL&FS raised fears of a liquidity crunch and contagion across the financial sector, prompting investors to aggressively sell housing finance stocks.
Concerns about rising borrowing costs, tighter liquidity, and the ability of NBFCs to refinance their liabilities added to the pressure. Indiabulls Housing Finance fell, although the company later maintained that it had adequate liquidity and a strong asset-liability position.
Zee Entertainment Enterprises Ltd
Zee Entertainment Enterprises Ltd is a leading Indian media and entertainment company engaged in television broadcasting, digital content, and entertainment. It operates a portfolio of television channels and digital platforms, serving audiences across India and international markets.
On January 25, 2019, Zee Entertainment’s shares plunged sharply by 33.5% in a single trading session after a media report linked an Essel Group-related entity to an SFIO investigation involving alleged suspicious transactions. Zee Entertainment denied having any connection with the entity mentioned in the report, but the news triggered significant investor concerns.
The sell-off was intensified by concerns over promoter debt and pledged shares. A large portion of the promoters’ Zee stake had been pledged as collateral, and lenders sold some of those shares following the sharp decline, adding further selling pressure and fears of additional pledge invocation.
Adani Enterprises Ltd
Adani Enterprises Ltd is the flagship incubator of the Adani Group, with businesses spanning airports, roads, mining and integrated resource management, data centres, solar manufacturing and other infrastructure-related sectors. The company develops and operates large-scale businesses across India.
On February 1, 2023, Adani Enterprises shares fell sharply by almost 35% in a single day and almost 50% in two days amid the continuing fallout from Hindenburg Research’s 2023 report. The report alleged stock-price manipulation and accounting irregularities across the Adani Group, claims that the group rejected.

Investor concerns intensified over the group’s leverage, valuations, and ability to raise capital. The sharp sell-off also came shortly after Adani Enterprises called off its Rs. 20,000 crore follow-on public offering, adding to uncertainty and selling pressure around the stock.
Indian Energy Exchange Ltd
Indian Energy Exchange Ltd is India’s leading electricity trading exchange, providing a technology-driven platform for trading electricity and related energy products. It facilitates transactions across the power market, including day-ahead, real-time, and other electricity contracts, connecting buyers and sellers through an electronic marketplace.
On July 24, 2025, Indian Energy Exchange (IEX) shares plunged nearly 30% after the Central Electricity Regulatory Commission (CERC) announced the phased implementation of market coupling, beginning with the Day-Ahead Market by January 2026.
The move raised concerns that centralised price discovery could reduce IEX’s competitive advantage and potentially affect its market share, transaction charges and revenue model. Since IEX had a dominant share of power-exchange volumes, investors reacted sharply to the potential impact on its future earnings.
PB Fintech Ltd
PB Fintech Limited is an Indian fintech company operating digital platforms such as Policybazaar and Paisabazaar. It enables consumers to compare and purchase insurance policies, while also providing access to lending and other financial products through its online platforms.
On September 24, 2026, PB Fintech shares plunged nearly 36% after IRDAI proposed changes to the economics of insurance distribution. The draft reforms included rationalising Expenses of Management, bringing back segment-wise commission limits and requiring greater disclosure of commission rates, raising concerns about the company’s revenue and profitability.
The proposals also included tighter rules on incentives, insurance distribution by banks and market infrastructure institutions, along with restrictions on compulsory insurance bundling. Investors feared that these changes could affect the commissions and distribution economics of platforms such as Policybazaar, triggering a sharp sell-off in PB Fintech shares.
