Parle Industries' Upper Circuit Triggers Market Frenzy: 5 Stocks that Witnessed Unprecedented Gains

Market Mayhem: Mistaken-Identity Rallies Continue to Plague Share Markets

Shares of Parle Industries surged sharply on May 20, hitting the upper circuit after investors mistakenly bought the company's stock in the wake of the viral Modi-Meloni "Melody" moment. Despite the company having no connection to Melody toffees or Parle Products, investors rushed to buy the stock, causing a dramatic rally.

This is not the first time that mistaken-identity rallies have occurred in the market. From oxygen shortages during the Covid-19 pandemic to Elon Musk's tweets and blockbuster IPOs, retail investors have repeatedly accidentally piled into similarly named stocks, triggering short-lived rallies. Here are some of the most dramatic share market rallies in recent times:

The Bombay Oxygen Investments Ltd rally in April 2021 is a striking example of a mistaken-identity rally. As medical oxygen shortages hit headlines and oxygen cylinder prices surged across cities, investors scrambled to buy shares linked to the sector. However, they mistakenly bought shares of Bombay Oxygen Investments Ltd, which had already exited the oxygen manufacturing business in 2019 and functioned primarily as a non-banking financial company. The stock jumped from Rs 11,025 on March 31, 2021 to an intra-day high of Rs 25,500 on April 20, 2021, delivering a massive 131.3 percent gain in less than 12 trading sessions.

Another famous case unfolded in January 2021 after Elon Musk tweeted just two words: "Use Signal." Traders mistakenly rushed into shares of unrelated US-listed microcap Signal Advance Inc, causing the stock to surge over six-fold immediately after the tweet and eventually skyrocketing over 5,100 percent within three trading sessions. Its market valuation ballooned from roughly $7 million to nearly $390 million despite the company having no relation to the messaging platform.

The pandemic also triggered confusion between video conferencing giant Zoom Video Communications and an unrelated company called Zoom Technologies Inc. As Zoom's popularity exploded globally during the work-from-home boom, investors mistakenly bought shares of Zoom Technologies because of the ticker similarity. The repeated confusion eventually pushed the lesser-known company to change its ticker symbol from ZOOM to ZTNO.

India saw another such episode on October 15, 2025 during the market debut of LG Electronics India. As investors rushed to buy into the blockbuster listing, many accidentally purchased shares of LG Balakrishnan & Bros Ltd, a Coimbatore-based auto component maker with no link to the consumer electronics giant. The stock jumped nearly 15 percent intra-day to Rs 1,600 before erasing gains and ending 1.6 percent lower at Rs 1,367.60 as investors realised the mistake.
