Alphabet (GOOGL) lost $477 billion in market value for the week through Friday's low, its worst week ever, after shares plunged $475 billion in one session on Thursday following third-quarter results. For October, the stock had shed about $766 billion at its low, second only to SpaceX's roughly $822 billion loss in July, and was down nearly 19% for the month, its steepest monthly drop since the 2004 IPO. Other megacaps also fell sharply, with Intel sliding as much as 30% after a weak outlook and Amazon losing about $70 billion for the week, while Eli Lilly, Tesla and SK Hynix added about $370 billion combined. UBS's chief investment office argued that retreating from markets does not protect portfolios and that investors should build resilient portfolios with exposure beyond tech. Alphabet closing at or below $280.50 on Friday would lock in its worst month since the IPO in percentage terms.

- $1,000 in UPS Stock 10 Years Ago: Did the Dividends Offset the Decline?
A $1,000 investment in UPS ten years ago would be worth $1,485.30 today, a 48.53% total return including reinvested dividends, while the share price is nearly where it started. Dividends did most of the work, as the quarterly payout rose from $0.78 to $1.64 and delivered $466.41 in cash. Over the same decade, the S&P 500 price change alone was 256.91%. UPS rode a pandemic surge to all-time highs, then declined as volumes normalized, labor costs rose and the company shed low-margin Amazon volume, cutting about 48,000 positions in 2025. The article says the income case remains intact, but the payout has held at $1.64 since early 2025 and the share price could stay flat again.

- The Tech Sell-Off is Putting the AI Trade on Notice. An Expert is Questioning Whether the Spending is Justified.
The Nasdaq Composite fell more than 3% on Friday, its worst day since June, as sell-offs in Amazon and Intel stock highlighted investor pressure on the AI trade. Investors increasingly want companies to show how large spending commitments will produce profits, rather than simply promising a place in the next technological revolution. Amazon reported negative free cash flow of $42.4 billion over the preceding 12 months, and its latest results indicated further increases in AI spending. Mark Vena, CEO and principal analyst at SmartTech Research, said investors are losing patience with AI spending that lacks clear payback dates, while Intel also faces weak PC demand and manufacturing challenges. He expects a more selective market that rewards companies turning adoption into profitable revenue.

- Joby Aviation's Dubai Launch Is the 1 Catalyst That Could Reverse a 73% Drop. Here's the Timeline -- and the Risk.
Joby Aviation (JOBY) shares have fallen about 73% from their 52-week high and recently traded around $4.69. The eVTOL aircraft maker plans to launch its first commercial air taxi service in Dubai before the end of 2026, under an agreement with the Roads and Transport Authority that grants six years of exclusive air taxi operating rights after commercial launch. The initial network of four vertiports includes one near Dubai International Airport, where a trip to Palm Jumeirah could drop from about 45 minutes by car to 10 minutes by air. Joby completed a crewed flight between two UAE locations in November 2025, but the launch still depends on regulatory approvals, operational readiness and completed infrastructure. Even a successful launch would not immediately make the company profitable, since early passenger volumes may be limited and manufacturing and expansion require substantial capital, while a delay could add pressure on the shares.
