Alphabet fell more than 12% in one day, and several technology heavyweights are 20%-30% below their 2026 closing highs. That has brought the familiar buying-the-dip question back into focus. Tiger's view: It is reasonable to start screening profitable companies after these pullbacks, but there is not enough evidence to declare a bottom across technology stocks. Prices, earnings and cash flow need to be assessed together—and historical recoveries show why the time horizon matters. 01 | Stock-level selloffs and index drawdowns differ On October 29, the Nasdaq Composite closed at 26,184.72, down 1.38%. The Nasdaq-100 fell 1.38%, while the S&P 500 lost 0.30%. GOOGL dropped 12.64%, Amazon fell 4.25%, Microsoft slipped just 0.16%, and Meta rose 1.96%. The performance was sharply divided. [1]

Memory chips, oil prices, Treasury yields and corporate earnings can seem like separate stories. Their connections become clearer when you trace how demand becomes revenue—and how much of that revenue ultimately turns into cash. Focus on the sources of growth, the spending needed to support it, and the cash left over. Valuation then helps explain why companies exposed to the same theme can offer different opportunities and risks. Here are the nine themes in our accompanying graphic, with a closer look at what to track. 01 | Memory: Read demand, pricing and capacity together For AI-related memory demand, watch whether orders become revenue, whether pricing supports margins, and when new capacity comes online. The relative pace of demand growth and supply expansion helps determine how long f

Elon Musk has raised a question for AI infrastructure investors: if demand keeps growing, why might some cloud providers struggle to survive? In an X post on October 25 U.S. time, Musk said debt markets had largely closed to companies without substantial revenue outside AI data centers. He said SpaceX had completed $40 billion in GPU debt financing, pointing to what he described as its investment-grade credit standing and revenue from Starlink and rocket launches. He then predicted widespread failures and consolidation among more than 200 neocloud companies, with relatively few making it through. Those statements about financing conditions, the number of providers, and their prospects are Musk’s assessment—not independently verified industry-wide findings. He did not specify a failure rate

The AI trade is facing one of its biggest tests yet. Last week, the Philadelphia Semiconductor Index fell roughly 11%, as investors grew increasingly concerned about AI infrastructure financing, elevated valuations and whether massive capital spending could eventually generate sufficient returns. Yet just as Wall Street begins questioning the economics of AI, Meta is preparing to report its Q3 earnings on October 21. And the company has already outlined an extraordinary spending plan: $130 billion to $145 billion in capital expenditures for 2026. That creates an interesting contradiction. AI infrastructure stocks are getting punished for spending too much, while Meta is preparing to defend one of the largest AI investment programs in the industry. So the real question going into earnings i

After nearly nine years of waiting, Tesla has finally unveiled its next-generation Roadster. And this time, it is not just another electric supercar. At an October 15 event in Texas, Tesla demonstrated a Roadster equipped with SpaceX-developed thruster technology, capable of briefly lifting off the ground, performing aerial maneuvers and even driving upside down using a specialized suction system. The company also showcased a 0–60 mph acceleration time of just 0.81 seconds and claimed a potential top speed exceeding 230 mph. Those are extraordinary numbers, although the demonstration results have not yet been independently verified for a production vehicle. The real question, however, is not whether Tesla has built a car that can briefly fly. It is why Elon Musk is promoting an extreme, hu

U.S. stocks showed a striking divergence in the latest trading session. The Nasdaq fell 1.88%, while the Philadelphia Semiconductor Index dropped 4.3%, marking its sixth consecutive daily decline. Oracle plunged nearly 9%, CoreWeave lost around 15%, and several AI infrastructure names remained under heavy pressure. Meanwhile, healthcare and consumer staples moved in the opposite direction, gaining approximately 2.4% and 2.1%, respectively, during the session. Traditional defensive names such as Procter & Gamble and Johnson & Johnson attracted renewed interest. On the same day AI stocks were being sold aggressively, companies selling everyday essentials and healthcare products were finding buyers. The interesting question is not simply why technology stocks fell. It is why investors

The U.S. midterm elections are just 20 days away, and Wall Street is starting to focus on a familiar question: If control of Congress changes, which sectors could face the biggest policy shifts? On November 3, Americans will elect all 435 members of the House of Representatives and roughly one-third of the Senate. Republicans currently control the White House and both chambers of Congress, but the elections could change that balance. For investors, the key is not simply whether Republicans or Democrats gain seats. It is how different congressional outcomes could affect financial regulation, crypto policy, energy investment, healthcare spending and AI infrastructure. Three scenarios are worth watching. Scenario 1: Republicans Retain Control of Both Chambers If Republicans maintain control o

Asian semiconductor stocks suffered a sharp selloff today. SK hynix dropped roughly 10%, Samsung Electronics fell 7.4%, South Korea’s KOSPI declined more than 5%, and Japan’s Kioxia also saw double-digit losses. What makes this interesting is that AI memory demand has not suddenly disappeared. Instead, investors are reacting to a potential shift in the global memory supply landscape, driven partly by a technological breakthrough from China. On October 12, Chinese memory manufacturer CXMT (ChangXin Memory Technologies) disclosed progress in its next-generation 4F² DRAM cell architecture, with plans to introduce server memory products using the technology by the end of this year. Compared with the industry’s mainstream 6F² structure, the new architecture could potentially increase memory den

U.S. stock indexes keep pushing toward new highs, but the number of stocks actually making money for investors may be much smaller than you think. According to Reuters, citing LSEG data on October 12, the S&P 500 has gained roughly 14% year to date, yet more than 200 of its constituents are still trading lower, with about a quarter down 11% or more. Even more striking, the median return among S&P 500 stocks is only around 4%. In other words, the index looks like it is enjoying a strong bull market, but investors who missed a handful of major winners may have significantly underperformed. The more interesting question is not whether the market has risen too much, but why so much of the rally is concentrated in AI and semiconductor stocks. SanDisk and Micron have each surged more tha

A new OpenAI investor disclosure is forcing the market to take a closer look at one of the most important numbers in the AI boom. According to the latest investor materials, OpenAI’s annualized revenue was approaching $50 billion at the end of September. That is still an extraordinary growth rate, but it is roughly $20 billion lower than the nearly $70 billion figure that had been circulating in the market just days earlier. The important point is that OpenAI did not suddenly lose $20 billion of revenue. The gap appears to come largely from different accounting and comparison methodologies. Some earlier estimates adjusted OpenAI’s revenue to make it more comparable with Anthropic, including revenue generated through cloud partners or distribution arrangements. OpenAI’s own reported run-rat

Samsung just delivered a set of numbers that look almost unreal. For Q3 2026, the company expects revenue of about KRW 195 trillion and operating profit of roughly KRW 107.4 trillion, or around $80.2 billion, up about 783% year over year. The main driver is still AI: HBM, traditional DRAM and NAND are all benefiting from tight supply, giving memory makers exceptional pricing power. What is more interesting is the market reaction. Despite the record-level profit, Samsung shares barely moved and remain well below their June high. That suggests investors are no longer asking, “How much can Samsung earn this quarter?” The question has shifted to: How long can these margins last? That is now the key debate across the memory sector. Demand is still strong. AI servers continue to absorb HBM, serv

Earlier this year, one of Wall Street’s favorite bearish narratives was the “SaaSpocalypse.” The logic was simple: if AI agents can write code, build apps and automate workflows, why would companies keep paying large recurring fees to Salesforce, ServiceNow and other software vendors? That fear hit the sector hard. The S&P 500 Software & Services Index fell more than 26% from late January to its April low. Now the story is starting to reverse. The software index has climbed to a new 2026 high, and earnings expectations are moving higher as well. LSEG data shows expected 2026 earnings growth for the software sector has risen from about 13.8% at the end of March to 20.6%. The key shift is that AI is starting to look less like an immediate replacement for SaaS — and more like a new mo

A new pattern is emerging across the AI infrastructure boom: the companies selling compute are starting to help finance the companies buying it. According to Anthropic’s IPO filing, Broadcom has agreed to provide up to $42 billion in financing to support Anthropic’s AI infrastructure buildout. The financing could cover roughly one-third of Anthropic’s five-year $125.2 billion TPU lease commitment and may include convertible instruments that could eventually become equity. The headline number is huge, but the structure matters even more. Broadcom is already deeply involved in Google’s TPU ecosystem and is expected to help Anthropic access roughly 3.5GW of next-generation TPU capacity starting in 2027. Now Broadcom is also helping Anthropic finance that infrastructure. So the relationship is

HDD stocks took a sharp hit in the latest session. $Seagate Technology(STX)$ and $Western Digital(WDC)$ both fell about 10.2%, even as the broader tech market held up much better. This was not a broad AI hardware selloff. The pressure was concentrated in HDD names, and the trigger came from Toshiba. Toshiba reportedly plans to invest around ¥60 billion to expand its Philippine operations and roughly double HDD capacity for AI data centers by fiscal 2027 compared with 2025 levels. The company is also targeting a much larger share of the global HDD market over time. That immediately raised a key concern for investors: if the industry’s No. 3 player starts adding meaningful capacity, how long can Seagate and W
