On Thursday, the primary stock indexes in the United States concluded the trading session with losses. Specifically, the Dow Jones Industrial Average saw a 1.2% decrease, settling at 48,908.72. The S&P 500 also declined by 1.2% to 6,798.40, while the Nasdaq experienced a 1.59% drop, closing at 22,540.58. Despite this overall market slump, several individual stocks stood out, drawing considerable interest from both retail traders and institutional investors throughout the day. This report examines five of these prominent companies: Amazon, IREN, Roblox, Reddit, and Strategy Inc., detailing their performance and the underlying reasons behind their market activity.
Shares of Amazon.com Inc. (NASDAQ: AMZN) ended the day down 4.42%, trading at $222.69. The stock fluctuated between an intraday peak of $226.31 and a low of $220.38, with its 52-week trading range spanning $161.43 to $258.60. Following the regular trading hours, Amazon's stock saw a significant decrease, plunging nearly 11% to $198.21. This decline occurred despite the company reporting robust fourth-quarter revenues of $213.39 billion, an increase of 14% year-over-year, surpassing market predictions. This growth was largely propelled by its Amazon Web Services (AWS) division, which expanded by 24%. However, the reported earnings per share (EPS) of $1.95 slightly missed expectations. The company also announced an optimistic first-quarter sales forecast and substantial capital expenditure plans, earmarking approximately $200 billion for investments in 2026.
IREN Ltd (NASDAQ: IREN) shares experienced a notable drop of 11.46%, closing at $39.79. During the trading day, the stock reached a high of $44.92 and a low of $38.90, contrasting sharply with its 52-week range of $5.12 to $76.87. In after-hours trading, IREN's stock plummeted further by 18.37% to $32.48. This downturn was attributed to the company's second-quarter financial results, which revealed a substantial loss of -$0.52 per share, falling short of the anticipated -$0.18. Despite a revenue increase to $71.21 million year-over-year, the earnings miss was a primary concern for investors, especially after the company had outperformed earnings estimates in the preceding quarter.
Roblox Corp. (NYSE: RBLX) also saw a decrease in its stock price, closing down 3.96% at $60.57. Its intraday trading ranged from $60.07 to $64.84, while its 52-week high stood at $150.59 and its low at $50.10. Despite the daily decline, Roblox shares showed resilience in extended trading, climbing 7.3% to $65. This rebound was fueled by the company's fourth-quarter report, which, while showing a loss of 45 cents per share (in line with estimates), highlighted a significant revenue surge to $2.22 billion, exceeding expectations. The company also reported strong user growth, with 144 million daily active users, and robust full-year momentum, including a 36% revenue increase and $1.8 billion in operating cash flow.
Reddit Inc. (NYSE: RDDT) stock declined by 1.07%, ending at $151.05. The stock's price moved between an intraday high of $155.34 and a low of $148.50, with its 52-week range between $79.75 and $282.95. In after-hours trading, Reddit's stock gained 4.55%, reaching $157.92. This positive aftermarket performance followed the company's strong fourth-quarter results, which surpassed estimates with $725.6 million in revenue and an EPS of $1.24. The company experienced a 70% year-over-year sales increase and a 19% rise in daily active unique users to 121.4 million. Furthermore, Reddit announced an upbeat first-quarter outlook and a $1 billion share buyback program, contributing to increased investor confidence.
Strategy Inc. (NASDAQ: MSTR) shares plummeted by 17.12%, closing at $106.99. The stock traded between an intraday high of $122 and a low of $104.17, nearing its 52-week low of $104.16, compared to its high of $457.22. The company's fourth-quarter report indicated revenues of $123.0 million and an adjusted EPS of $16.37, exceeding analyst expectations. While revenue growth was modest at 1.9% year-over-year, driven by subscription-related segments, the stock's significant fall was largely influenced by broader market pressures affecting Bitcoin, as Strategy Inc. holds a substantial amount of the cryptocurrency. As of February 1, 2026, the company held 713,502 bitcoins, and its balance sheet had expanded significantly to $2.3 billion in cash.
In summary, the market's performance on Thursday saw a general decline across major U.S. indexes. However, the individual trajectories of Amazon, IREN, Roblox, Reddit, and Strategy Inc. presented a complex picture, driven by their respective earnings reports, operational highlights, and broader market influences, particularly in the tech and crypto sectors. These movements underscore the dynamic nature of stock valuations and the importance of detailed financial analysis for investors.
