Top 10 Stocks with the Biggest Downfall in 2025

1. Deckers Outdoor (DECK) — Down 49.2%

Deckers Outdoor, a footwear company, led the S&P 500 in losses with a staggering 49.2% drop in 2025. Despite posting a 17% revenue increase in late 2024, concerns about the broader economic environment and high valuation multiples have weighed heavily on the stock. Investors remain cautious due to uncertain growth prospects amid global trade tensions and tariffs26.

2. Siemens — Market Cap Decline of 47%

Siemens, a major industrial conglomerate, saw its market capitalization shrink by nearly half, from Rs 3.35 lakh crore to Rs 1.76 lakh crore. The stock price has dropped around 25% year-to-date, reflecting challenges from geopolitical uncertainties and reduced investor confidence in industrial sectors1.

3. ON Semiconductor (ON) — Down 43.8%

ON Semiconductor, heavily reliant on automotive industry demand, has suffered a 43.8% decline. The company announced restructuring plans and layoffs due to slumping demand, particularly in the automotive segment, exacerbated by tariffs and economic slowdown fears236.

4. Charles River Laboratories (CRL) — Down 43.3%

Charles River Laboratories, a contract research organization, has experienced a 43.3% drop. The decline is linked to reduced spending in pharmaceutical research and development amid economic uncertainty2.

5. Teradyne (TER) — Down 41.5%

Teradyne, a supplier of automated test equipment, saw its stock fall 41.5% as slowing demand in tech hardware and semiconductor sectors impacted its earnings outlook24.

6. Zebra Technologies (ZBRA) — Down 41%

9. Adani Green Energy — Market Cap Decline 17%

Adani Green Energy’s market cap fell 17%, with its share price plunging 55% over six months. The decline is attributed to sector-specific challenges and broader market sell-offs in renewable energy stocks1.

10. Tesla (TSLA) — Down 35.8%

Tesla’s stock has fallen 35.8% in 2025, impacted by declining profit margins, increased competition, and political controversies surrounding CEO Elon Musk. The company’s automotive revenue dropped 8% in the last quarter of 2024, and ongoing tariffs and consumer backlash have further pressured the stock2346.

Factors Behind the Downfall

Several common themes have contributed to the downfall of these stocks in 2025:

  • Geopolitical Uncertainty and Tariffs: Trade tensions, particularly policies from the Trump administration, have created volatility and disrupted supply chains, affecting industrial and tech stocks13.

  • Economic Slowdown Concerns: Fears of a recession and slowing global growth have led to decreased consumer spending and reduced demand in automotive, technology, and retail sectors36.

  • Sector-Specific Challenges: Semiconductor manufacturers, renewable energy firms, and retail companies have faced unique headwinds, including restructuring costs, regulatory hurdles, and shifting consumer preferences126.

  • Valuation Pressures: Many stocks entered 2025 with high valuations, making them vulnerable to sharp corrections when growth expectations were not met6.

What This Means for Investors

The significant declines in these top 10 stocks highlight the importance of thorough research and cautious investing amid uncertain market conditions. While some companies may recover as economic conditions improve, others could face prolonged challenges. Investors should evaluate fundamentals, sector trends, and geopolitical risks before making decisions.
