behavioral-finance

behavioral-finance is a skill for Claude Code, Codex from skloxo/TideTrading. It costs 42 tokens per session (2,377 once invoked), scanned A, a copy of behavioral-finance, MIT.

A framework for applying behavioural finance, the study of predictable ways investors depart from fully rational decisions, to trading and portfolio design. It covers sentiment, overreaction, underreaction, momentum, reversal, and bias checks.

In plain words
What is it for?
Use it to interpret momentum and reversal strategies, identify extreme-sentiment opportunities, analyse retail-driven Chinese A-share behaviour, and add bias controls to quantitative portfolios.
Why use it?
It helps explain why prices may respond too slowly or too strongly to information. It also provides checks intended to reduce the effect of common investor biases on decisions.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

behavioral-finance scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 12d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Behavioral Finance Applications

Overview

Translate behavioral-finance theory into quantifiable trading signals and risk-control rules. Core assumption: market participants systematically deviate from rational decision-making, and these biases can be predicted and exploited.

Applicable scenarios:

  • Behavioral interpretation and parameter optimization for momentum / reversal strategies
  • Contrarian signals when market sentiment becomes extreme
  • Debiasing mechanisms in portfolio construction
  • Capturing behavior patterns specific to retail-driven China A-share markets

Core Concepts

Overreaction and Underreaction

Underreaction → momentum effect:

Mechanism: anchoring bias + conservatism
  Investors anchor on old information and update insufficiently to new information
  After an earnings beat, the stock price digests it gradually rather than all at once
China A-share evidence:
  - Earnings-guidance beats still produce 3-5% excess return over the following 20 days
  - After analyst rating upgrades, momentum often persists for 1-3 months
Quant signal:
  SUE (standardized unexpected earnings) > 2σ -> buy and hold for 60 days
  Top 10% 20-day return -> continue holding for 20 days (China A-share momentum cycles are shorter)

Overreaction → reversal effect:

Mechanism: representativeness heuristic + availability bias
  Investors extrapolate recent trends too aggressively and ignore mean reversion
  Panic / euphoria drives reactions beyond what fundamentals support
China A-share evidence:
  - Rebounds after consecutive limit-downs (after 3 limit-downs, the average 20-day rebound is 8%)
  - Big annual losers often earn 5-10% excess return the next year
Quant signal:
  Bottom 10% of 250-day return -> buy and hold for 250 days
  RSI(5) < 10 -> short-term rebound signal (5-10 days)

Key distinction:

Dimension Underreaction (Momentum) Overreaction (Reversal)
Time scale 1-12 months <1 week or >12 months
Information type Clear events (earnings / announcements) Ambiguous information (sentiment / trend)
Best China A-share window 20-60 days 5-10 days (short term) / 1 year (long term)
