股票市场效率无法像博彩市场那样直接验证，因为股票不存在固定揭晓时间，真实价值始终取决于未来现金流，因此金融学始终存在Joint Hypothesis Problem：任何异常收益都无法证明市场无效，因为也可能只是定价模型本身错误。同时作者区分了“Prices are Right”和“No Free Lunch”两个概念，价格存在偏离，并不意味着能够稳定套利，因为套利成本可能高于错误定价本身。 连续双向竞价（Continuous Double Auction）本身就是市场效率的重要来源。Hayek、Vernon Smith以及Zero-Intelligence Trader研究共同说明，即便参与者并不聪明，只要交易机制合理，市场仍能快速逼近有效价格。因此市场制度的重要性甚至可能超过市场参与者本身的能力。 股票市场真正进入“群体疯狂”的根源，是认知多样性的崩塌。当投资者逐渐形成相同叙事、相同时间框架以及相同交易规则时，市场开始偏离价值。长期投资者倾向于围绕现金流定价，而短周期投资者更容易外推近期价格，因此实验中短周期市场持续形成泡沫。Narrative进一步强化这种过程，使情绪、故事与价格互相反馈，最终形成Boom或Bust，而这种崩塌往往呈现非线性，一点点认知收敛即可引发巨大价格波动。 Michael Mauboussin最终给出的交易框架可以浓缩为一句话：市场绝大多数时间体现的是群体智慧，因此价格通常有效；真正值得交易的机会来自群体智慧失效之后的群体疯狂。交易员真正需要监测的并非价格本身，而是认知多样性是否正在消失。 实践中，极端情绪（Sentiment）、剧烈价格运动（Major Price Move）以及极端估值（Extreme Valuation）同时出现，是认知多样性崩塌最常见的表现，也是市场最容易出现重大反转和超额收益机会的位置。

One of the best parts of my trip to Japan was getting to meet so many friends from the Renaiss community. 💜 Thanks our boss @Plus_Ultra_715 for treating us to delicious foods~ Glad @SiNaToDdFelix, @corang_ee, @lilyuzuu, @harryinhk ,@StephenSu9527, @wonnie ,@Mark_Memelord, @snoopylee115 joined our Renaiss lunch. It was so nice spending time talking about collectibles, cards, and everything with each other. After lunch, we headed to Akihabara together to check out some card shops. Huge thanks to @wonnie for inviting me to open a pack… and somehow I pulled Nami! ✨ Collecting has never been just about owning a card. It’s about the people you meet, the memories you make, and the connections you build along the way. Thank you to everyone who made this Japan trip so memorable, and creating these moments with Renaiss. Looking forward to seeing Renaiss community in another region! @renaiss_cmty @renaissxyz

It’s hard to describe just how far out in front of us is China 2026. Luckily record numbers are checking out for themselves. Increasingly visa-free travel makes it easier than it’s ever been. I’ve just been on a “High-speed train” which description fails to do justice. It travels like the wind. If you closed your eyes you wouldn’t know you were moving. China has 50,000 miles of it. It links cities so far better than ours it brings me to tears. Clean. Crime free. The cops don’t carry guns and their cars don’t have sirens, only flashing lights. Prices are so cheap I’m scared to tell you. A slap up lunch £2.50. Shirts £12. Deluxe taxis (BMW electric) £4. And this in a Tier 1 City (Beijing Shanghai Guangzhou Shenzen). It’s cheaper elsewhere! The shops are tumbling with goods from the west (at Chinese prices - western goods are of course mainly made in China) from the east often Russia and from a home manufacturing base easily the biggest in the whole world. Nobody litters or jaywalks, nobody lays in shop doorways, nobody begs. Vertiginous towers of bewildering variety arise everywhere. At night these cities don’t even look real. I have a young wife. When she was born Shenzen was a one-horse town nobody outside had ever heard of. Today it is a Wonder of the World. One of dozens. If you deny it, you’re a fool. George Galloway

❤️🇺🇸 Nothing beats a weekend spent with family. Donald Trump Jr., his wife, and the entire Trump family enjoying a relaxed family lunch together. In a busy world, moments like these remind us that family, love, and togetherness matter most. Wishing everyone a wonderful weekend with the people who mean the most. ☀️🍽️❤️ #TrumpFamily# #Togetherness#

A SpaceX intern once described eating lunch next to Elon Musk in the company cafeteria. The intern said Elon sat down at a regular table with a regular tray of food. No entourage. No reserved section. He sat next to two junior engineers who were clearly terrified. One of them was explaining a problem with a valve component to the other. Elon listened without introducing himself or interrupting. After about three minutes he turned to the engineer and said "have you tried running it at a lower pressure gradient first." The engineer stared at him. Then realized the CEO of the company had just casually solved a problem his team had been stuck on for a week. The intern said what happened next was the part that surprised him. Elon didn't leave. Didn't check his phone. He spent the next twenty minutes asking the engineers questions about their work. Not CEO questions about timelines and budgets. Engineering questions about fluid dynamics and material stress tolerances. He was genuinely curious. The cafeteria conversation was indistinguishable from a technical review. The intern said he understood in that moment why people work 80-hour weeks for this man. Not because he's inspiring. Not because he pays well. Because he's the only CEO in the world who sits in the cafeteria and solves your engineering problem between bites of a burrito. People follow leaders who are above them. People worship leaders who sit next to them and prove they understand the work better than the people doing it.

The Crown Prosecution Service has confirmed our dear friend Ann Widdecombe was eating lunch when Joshua Kerry allegedly arrived at her house and entered through the front door. He then allegedly hit her on the head with a hammer 21 times. Before allegedly driving off. Why did the police and Keir Starmer tell Nigel Farage it was a “burglary gone wrong”? The authorities had better preserve all files and records. As Home Secretary in a Reform government I will take a keen interest in all communications in those initial hours. I will ensure the public learns the truth.
