February 11, 2025, was a day of notable shifts in the stock market, characterized by significant movement in individual stocks even as broader market indices presented a mixed picture. Analysis of Wall Street Journal data, focusing on actively traded stocks meeting specific price and volume criteria, reveals the day’s most compelling market movers, driven largely by company-specific news.

Top Percentage Gainers

Leading the market’s upward momentum was Firefly Neuroscience Inc. (AIFF), which experienced an extraordinary surge of over 170% on exceptionally high trading volume. This dramatic increase followed Firefly’s announcement of its acceptance into the NVIDIA Connect program. The collaboration with NVIDIA, granting access to advanced hardware and software, is intended to accelerate Firefly’s development of AI-driven neuroscience applications using its Brain Network Analytics (BNA™) technology.

Other top percentage gainers, based on Wall Street Journal’s criteria, included:

• Society Pass Inc. (SOPA): Soaring by over 120%.
• Global Star Acquisition Inc. Cl A (GLST): Climbing by approximately 43%. Lingering positive sentiment may stem from a recent shareholder approval of merger proposals on February 3rd [Source: Investing.com].
• Lipella Pharmaceuticals Inc. (LIPO): Jumping by over 41%. Investor enthusiasm was fueled by Lipella’s report of positive topline Phase 2a results for its LP-310 treatment for Oral Lichen Planus, showcasing clinically meaningful improvements.
• SelectQuote Inc. (SLQT): Rising by nearly 31%. A positive market reaction followed SelectQuote’s release of strong second quarter fiscal year 2025 results on February 10th, demonstrating significant revenue and net income growth.

These substantial gains highlight the power of company-specific news, such as strategic partnerships, clinical trial advancements, and robust earnings, to drive significant stock appreciation.

Top Percentage Losers

Conversely, several stocks experienced sharp declines. Fitell Corp. (FTEL), despite showing earlier gains, ended the day as the top percentage loser according to Wall Street Journal data, plummeting by over 53%. Interestingly, Fitell had announced the closing of a $10 million registered direct offering on February 10th (Press Release). While capital raises are sometimes viewed positively, the market reaction for Fitell was decidedly negative, suggesting potential concerns beyond the financing itself.

Other significant percentage decliners included:

• Fluence Energy Inc. (FLNC): Decreasing by over 46%. Fluence Energy’s stock price reacted sharply to a lowered outlook, following the release of their First Quarter 2025 results and reduced full-year guidance (Press Release). Customer delays and increased competition were cited as key factors.
• Bellevue Life Sciences Acquisition Corp. (BLAC): Falling by over 42%. Negative sentiment appears to be weighing on BLAC, with recent reports highlighting “concerning financial metrics” and a “52-week low” for the stock [Source: Investing.com].
• Columbus McKinnon Corp. (CMCO): Sliding by over 41%. (Note: There is a data discrepancy as WSJ data also lists CMCO as a top gainer. However, press releases indicate positive news. This decline might be a data error). Columbus McKinnon announced a major strategic combination with Kito Crosby (Press Release), a $2.7 billion deal expected to create significant value. The listed decline in WSJ data may be an anomaly.
• Third Harmonic Bio Inc. (THRD): Dropping by over 30%. Despite announcing positive Phase 1 clinical results for THB335 (Press Release), Third Harmonic Bio still experienced a significant stock decline. This highlights that positive clinical data alone isn’t always sufficient to drive stock appreciation, especially when broader market or sector headwinds exist.

Notable Active Stocks (by Volume)

• BigBear.ai Holdings (BBAI)
• NVIDIA Corp (NVDA)
• Palantir Technologies (PLTR)
• Tesla (TSLA)
• Super Micro Computer (SMCI)

These consistently high-volume stocks, particularly within the technology sector, underscore ongoing investor focus on these companies.

Conclusion

February 11, 2025’s market activity underscores the significant impact of company-specific news on individual stock performance. While overall market trends provide a backdrop, strategic announcements, earnings reports, and clinical trial data are powerful catalysts driving daily market movements. Discrepancies in data across sources highlight the importance of consulting multiple financial resources and seeking professional financial advice for informed investment decisions.
