During the final week of January, retail investor forums including X and Reddit's r/WallStreetBets exhibited heightened activity centered around five key stocks: Microsoft Corp. (NASDAQ:MSFT), SanDisk Corp. (NASDAQ:SNDK), Meta Platforms Inc. (NASDAQ:META), Apple Inc. (NASDAQ:AAPL), and UnitedHealth Group Inc. (NYSE:UNH). This group spans multiple industries — from technology and semiconductors to social media and healthcare insurance — underscoring the broad interest among individual investors driven by earnings results, AI developments, and corporate news flow.
Microsoft: Robust Revenue Growth Tempered by Capital Expenditure Concerns
Microsoft's fiscal second-quarter earnings, announced on January 28, highlighted a solid performance with revenue reaching $81.27 billion, exceeding Wall Street estimates. Adjusted earnings per share settled at $4.14. A notable milestone was Microsoft Cloud's revenue surpassing $50 billion, powered mainly by vigorous Azure growth estimated in the 38 to 39 percent range and increased AI demand.
However, investor discussion also revolved around Microsoft's substantial capital expenditures of $37.5 billion reported during the quarter. This surge in spending sparked debate over its potential impact on profit margins, the sustainability of aggressive investment, and whether the cloud infrastructure acceleration might proceed more slowly than anticipated.
Stock performance reflected mixed sentiments, with shares trading around the $433 to $435 mark near article publication. Over 12 months, the stock appreciated by approximately 4.46%, but it fell 15.54% in the preceding six months. Analysis firm Benzinga's Edge Stock Rankings assigned a solid quality rank to Microsoft while indicating weakness in price trends over the short, medium, and long term.
SanDisk: Outstanding Earnings Driven by Data Center Storage Demand
SanDisk captured investor enthusiasm following the release of its fiscal second-quarter earnings on January 29. The company delivered markedly impressive adjusted EPS of $6.20, far surpassing analyst expectations which ranged roughly between $3.49 and $3.62. Revenue came in at $3.03 billion, a 61 percent increase year-over-year and significantly above the forecast range near $2.67 to $2.69 billion.
Underlying this stellar performance was booming AI-related demand fueling growth in the data center storage sector. Specifically, data center sales jumped 76 percent year-over-year and 64 percent sequentially to $440 million. This surge occurred despite constraints in NAND supply and contributed to continued pricing power. Furthermore, SanDisk solidified its manufacturing footprint by extending its Yokkaichi joint venture with Kioxia through 2034.
Retail investors have conversed about SanDisk positioning itself as a potential replacement for Microsoft within the influential Magnificent 7 equity group, following its remarkable rally. Price-wise, SanDisk’s shares traded near $539 to $546, with a 52-week range extending from $27.90 to $546.75. The stock experienced an extraordinary gain exceeding 1,398.06 percent over the last year and surpassed 1,142.91 percent over the past six months. Price trends rated stronger across all timeframes according to Benzinga's Edge Stock Rankings.
Meta Platforms: Earnings Beat and Optimistic Guidance Strengthen Shares
Meta Platforms' fourth-quarter earnings announcement delivered a positive surprise, with reported revenue of $59.89 billion and adjusted EPS of $8.88. This outcome was supported by vigorous advertising demand, seasonal holiday momentum, and early benefits from AI enhancements improving ad performance and user engagement metrics.
The company’s outlook further bolstered investor confidence. For the first quarter of fiscal 2026, Meta projected revenues between $53.5 billion and $56.5 billion. Annual expenditures were guided toward a range of $162 billion to $169 billion, along with a pronounced increase in capital expenditures to between $115 billion and $135 billion.
Despite prevailing strength, some retail investors expressed regret about missing opportunity windows in Meta’s recent gains. Shares traded close to $730 to $739 at the time of writing, with a 52-week high of $796.25 and a low of $479.80. The stock gained approximately 7.47 percent over the year and 6.20 percent in the last six months, showing a robust price trend and moderate valuation metrics in the Benzinga Edge rankings.
Apple: Record Revenue and iPhone Demand Drive Strong Quarter
Apple reported blockbuster results with revenue hitting $143.8 billion, marking a 16 percent year-over-year increase and exceeding estimates near $138 to $139 billion. Diluted earnings per share reached $2.84, bolstered by record-breaking demand across all geographic regions for the iPhone. The company’s services division continued solid growth, and the active installed base surpassed 2.5 billion devices.
Looking ahead, Apple forecasted March quarter revenue growth in the 13 to 16 percent range year-over-year, accompanied by gross margins expected around 48 to 49 percent. The product lineup was refreshed with the launch of a second-generation AirTag, featuring an expanded range, improved speaker volume, and enhanced Precision Finding capabilities.
Some retail investors poked light-hearted fun at Apple for a circumspect presentation of iPhone sales figures. Shares traded near $258 to $260, within a 52-week range of $169.21 to $288.61. Over 12 months, the stock returned 8.71%, advancing 23.55% in six months, with a strong longer-term price trend and solid quality ratings but weaker short- and medium-term trends noted.
UnitedHealth Group: Mixed Earnings and Medicare Advantage Proposal Prompt Volatility
UnitedHealth Group's full-year and fourth-quarter earnings disclosures dominated conversation this week, coupled with news of a restrictive Medicare Advantage proposal. The company announced $447.6 billion in full-year 2025 revenue and adjusted EPS of $16.35. Fourth-quarter results showed revenues of $113.22 billion and adjusted EPS of $2.11.
However, the January 26 proposal for a nearly flat 0.09 percent net Medicare Advantage rate increase for 2027 triggered a notable sell-off in UnitedHealth shares. Despite this, retail investors remained hopeful for a rebound, indicated by ongoing interest in call options.
UnitedHealth traded around $291 to $293 per share, within a 52-week range from $234.60 to $606.36. The stock depreciated by approximately 46.42 percent over the year but recorded a 9.87 percent gain in the last six months. Benzinga’s Edge Stock Rankings illustrated a weak price trend across all time horizons and a moderate value rating.
