The AI Trade Just Broke. The New Test Is Revenue, Power, and Cash Flow.
Last week, Goldman Sachs’ prime brokerage book saw the largest technology-stock selloff on record. Rich Privorotsky, head of European FICC and equities trading at Goldman Sachs, gave the number in an interview from the bank’s London trading floor. He did not call it a correction or a pullback. He said the crowded “long AI, short everything else” trade was being painfully deconstructed.

The Economist Who Monetized Trust
On Oct. 24, 2026, the WeChat account “Zeping Macro” showed one line: “This account cannot be followed due to a violation.” Customer service called it a “platform technical adjustment affecting 15 days.” Three months earlier, the account had been tied to a paid-member blowup that cost one person more than 10 million yuan. In October 2024, it had already been temporarily blocked after a public fight with investor Dan Bin. An account with millions of followers does not keep hitting platform limits by accident.

The Numbers ByteDance Wins, and the Ledgers It Doesn't
"ByteDance is double-short Hang Seng Tech." The line has circulated in Hong Kong stock narratives in 2026. Li Liang, vice president of Douyin Group, publicly denied it, calling it organized hype by marketing accounts. The denial is accurate: ByteDance is unlisted and not in the index. The metaphor has life because it captures a structural asymmetry. Six of the top ten weighted stocks in Hang Seng Tech compete directly with ByteDance, with a combined weight around 40 percent. Alibaba, Meituan, Tencent, Kuaishou, JD.com , and Baidu. To buy Hang Seng Tech is to indirectly hold a portfolio that ByteDance keeps eroding, without being able to hold the eroder.

The Casino Doesn’t Have to Cheat. It Just Has to Wait.
Lao Chen is a small business owner I know. He sells building materials, saved for more than a decade, and had 500,000 yuan in spare cash. In 2019 he went to Macau for the first time. When he came back I asked him how it felt. He said, “Not bad. I won 80,000.”

The T-Trap: Why Averaging Down Feels Like Progress and Rarely Is
My friend got stuck in an automaker's stock and started doing T like crazy, short-term trading around his existing position. He dragged his average cost down from over 100 to the 80s, which sounds like a beautiful self-rescue. Every night at 9:30 sharp, he opens his trading app. The phone light shines on his face. His finger hovers over the buy and sell buttons. He mutters, "T'd out another two mao." The stock keeps falling, and he keeps doing T. In one phrase: T-ing without end.

Is Gold Going to Skyrocket? Why Steady Demand Matters More Than Fireworks
Picture a retired schoolteacher. Call her Margaret. She started watching gold in 2019. It was around $1,300 an ounce then, and she thought it was expensive. She waited. At $2,000, she was sure it had peaked. She waited again.

Why Is the 1983 Penny So Valuable? The Transition-Year Errors Worth Looking For
It usually starts the same way. Someone empties a coin jar onto the kitchen table, scrolls past a headline claiming a “1983 penny could be worth thousands,” and starts squinting at dates. Before long, a few 1983 cents are sitting in a plastic bag, set apart like lottery tickets.

China’s 4.6% GDP Looks Calm. The Quarterly Curve Tells a Different Story
In the first three quarters of 2026, China’s GDP reached 107.1071 trillion yuan, up 4.6% from a year earlier at constant prices. Quarterly growth was 5.0%, 4.3%, and 4.5%. The three numbers together say more than the cumulative 4.6%. The path is uneven because policy made it uneven. Fiscal spending and special bond issuance moved early and pushed the first quarter to 5.0%. Project reserves thinned and bond issuance slowed, so the second quarter fell to 4.3%. Exports then took over in the third quarter and pulled growth back to 4.5%. The shape of the line shows what is holding the year up, where policy has pulled back, and how far down the list domestic demand sits.

Japan Isn't Losing to India. It's Losing to Itself.
The IMF's latest World Economic Outlook has produced a headline eye-catching enough: Japan's nominal GDP will be overtaken by both India and the United Kingdom in 2027, falling from fourth globally to sixth. Japanese media framed it as "the continued decline of Japan's status as an economic power," and most market attention landed on "Japan has dropped another place."
