Behavioral Investing Biases

171.为什么牛市后期更容易亏钱？｜半年度投资账复盘 adds the late-bull-market version: regret aversion can make “I missed the gains” feel like an actual loss, pushing investors to enter late, trade too frequently, and increase exposure to hot or lottery-like assets just as Market Breadth Narrowing / 市场广度收窄 and volatility make mistakes more costly.

Behavioral investing biases are the predictable mental shortcuts and emotional reactions that push investors away from disciplined decision-making. EP69 AI时代来临，投资不再是单机模式 names loss aversion, confirmation bias, herding, and anchoring as common ordinary-investor failure modes, especially when social-media feeds amplify the information the investor already wants to believe. EP64 投资路上踩坑无数，如今的我刀枪不入 adds the fraud version: early small wins, teacher authority, peer screenshots, fear of missing out, shame after being cheated, and refusal to read contracts can all make an investor cooperate with the scam. EP28 百年金融诈骗史：阶级跨越与锒铛入狱的距离 adds a longer fraud-history version: Ponzi Scheme, Advance-Fee Fraud, Penny Stock Boiler Room Fraud, and Pig Butchering Scam all exploit the same desire for special access, social belonging, and easy certainty.

泡沫的四个必要不充分条件 | 对谈经济学者朱宁教授 adds 朱宁 / Zhu Ning’s bubble-cycle version. The episode emphasizes overconfidence, linear extrapolation from recent price moves, and herding after neighbors or social circles appear to make money. It also adds an AI-specific twist: investors may suffer both from model hallucinations and from the illusion that access to AI tools makes them institutionally equivalent to professional investors.

The concept overlaps with Retail Bull Market Psychology and Retail Investor Crowding, but it is more individual and process-level. Retail bull-market psychology describes the social pull of fast gains; behavioral investing biases describe why a single investor sells winners too early, averages down from hope, follows a big influencer without understanding the trade, or compares a stock to an old high price after the business context has changed.

E144.交易的艺术：不预测，统计优势，分散红利，随机波动 adds the post-hoc narrative version through Random Market Narratives. The random market experiment shows how investors can invent coherent reasons after observing winners and losers, then treat those reasons as if they were known causes.

E145.上钟了！4000点之上的心理按摩 adds the profit-retention version. In a hot A-share market, investors can anchor to index points, compare dividend assets with faster growth stocks, treat floating gains as owned money, and become trapped between regret over selling early and fear of losing gains.

139. 泡泡玛特和拼多多值得投资么？ adds the suitability version through ICE. If a person is not behaviorally suited to short-term trading or active stock picking, more information and better AI summaries may simply create more confident mistakes. Avoiding an unsuitable game can be part of disciplined investing rather than a failure to learn.

vol.101.既安全、收益又高、流动性还好的投资到底存在吗？ adds the liquidity version. The episode argues that stocks, funds, and other liquid assets can be too easy to sell or repurpose, so the investor may need an Investment Liquidity Tradeoff plan to keep long-term money from being interrupted by short-term fear, excitement, or household spending pressure.

vol.105.如何判断一个投资组合是否适合自己？ adds the news-impulse version. The source warns against letting urgent social-media language, Trump-trade analogies, or sudden market headlines drive repeated large allocation changes, and introduces Investment Cooldown Discipline as a way to slow action.

155.美貌能当饭吃吗?想赚钱该做点啥?拮据时应避免什么行为?经济学思维有什么用？ adds a general-reader explanation of Loss Aversion / 损失厌恶. The episode contrasts virtual stock trading with real-money investing to show why ownership and reference points make losses harder to process than hypothetical drawdowns.

vol.110.投资就是对世界观的投票｜《迈出资产配置第一步》完结篇 adds the Risk Perception and worldview version. The source argues that people do not only miscalculate risks; they feel them through personality, upbringing, rules, optimism, pessimism, and social models, which helps explain why copying another investor’s method can become behaviorally impossible.

vol.121.从昙花一现的分级基金到风头正劲的杠杆ETF：永远不要低估人性的疯狂 adds the leverage-product version. Once investors experience B-share or leveraged ETF days with unusually large gains, the source argues that the ordinary return rhythm can feel intolerably slow, making Leveraged Product Suitability as much a behavioral-control problem as a product-knowledge problem.

134. 投资大师系列先导篇：“他们不只赚了很多钱，更创造了理解世界的方法” adds the hero-copying version through Investor Idol Risk / 投资偶像风险. The bias is not only liking a famous investor; it is using a famous person’s conviction to bypass one’s own sizing, liquidity, time-horizon, and competence checks.

Key Claims

  • Loss aversion can make investors take small gains quickly while holding or adding to losing positions.
  • Confirmation bias can turn AI Investment Research or social feeds into a search for evidence that protects an existing view.
  • Herding can make influencer trades feel safer even when the risk belongs entirely to the follower.
  • Anchoring can make past prices look like fair values even when fundamentals, policy, or market regimes have changed.
  • Investment Decision Logging can reduce bias by forcing the investor to state the reason, evidence, and invalidation conditions before memory rewrites the story.
  • Small early payouts can exploit confirmation bias by making the investor search for reasons the opportunity is real.
  • Prestige and exclusivity can exploit authority bias, as in elite-access or high-minimum investment stories.
  • Advance-fee and pig-butchering scams exploit sunk cost because each new payment is framed as the final step before recovery or reward.
  • Shame after a loss can delay help-seeking, reporting, and recovery, which turns the first mistake into larger damage.
  • Outsourcing judgment to a teacher, group, sales consultant, or platform is itself a behavioral risk when incentives and accountability are unclear.
  • Post-hoc explanation can make random or contingent outcomes feel inevitable after the price chart is visible.
  • A trend signal should not become confirmation bias; E144 treats it as an input to a repeatable system, not as proof that a story is true.
  • E145 adds that unrealized gains create their own bias: once an investor mentally owns a high-water mark, normal volatility can feel like a personal loss.
  • Zhu Ning adds overconfidence, recent-trend extrapolation, and herding as the recurring psychological substrate behind Bubble Necessary Conditions.
  • AI tools can reduce information friction while still reinforcing confirmation bias if the investor asks them to rationalize a desired trade.
  • Self-knowledge is a behavioral control: an investor should know whether their temperament fits short-term trading, long-horizon holding, or no active stock picking at all.
  • Liquidity can amplify bias when easy redemption makes it painless to abandon a long-term plan during volatility or excitement.
  • Vol.105 adds that the desire to react immediately to news is itself a behavioral risk when the portfolio is rebuilt several times a year.
  • Episode 155 adds that real-money ownership intensifies loss aversion compared with simulated decisions.
  • Vol.110 adds that a strategy borrowed from a mismatched worldview can create hidden behavioral risk even before market losses arrive.
  • Vol.121 adds that leverage can reshape an investor’s reference point: after seeing amplified daily gains, ordinary unleveraged returns may feel psychologically insufficient.
  • Episode 134 adds that admiration can become confirmation bias when the investor searches for a master whose view legitimizes the trade they already want.
  • Episode 171 adds that regret aversion can mislabel late-cycle nonparticipation as a loss and make chasing feel like loss repair.
