"grad-behavioral-finance"

"grad-behavioral-finance" is a skill for Claude Code from charlieviettq/awesome-agent-skill. It costs 83 tokens per session (920 once invoked), scanned A, a copy of grad-behavioral-finance, MIT.

A field that explains investor and market behavior through recurring psychological biases rather than assuming every investor makes fully rational decisions.

In plain words
What is it for?
Use it to analyze market anomalies, find decision biases in portfolio management, understand investment mistakes, and design ways to reduce those biases.
Why use it?
It helps explain patterns such as bubbles, crashes, momentum, and holding losing investments that standard financial models may not explain well.

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

"grad-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 9d 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

Overview

Behavioral finance challenges the rational-agent assumption by documenting systematic cognitive biases that affect investor decisions and market prices. Anchored in Kahneman and Tversky's prospect theory (1979), the field explains persistent anomalies that traditional finance cannot.

When to Use

  • Explaining market anomalies (momentum, bubbles, crashes) through investor psychology
  • Diagnosing decision biases in portfolio management
  • Designing de-biasing strategies for investment processes
  • Evaluating why "rational" strategies underperform expectations

When NOT to Use

  • As a catch-all explanation for any price movement — biases must be identified specifically
  • When standard rational models already explain the phenomenon adequately
  • For normative portfolio construction without considering limits to arbitrage

Assumptions

IRON LAW: Investors are NOT rational — systematic biases create
predictable pricing errors. These errors persist because arbitrage
is limited (costs, risk, horizon constraints).

Key assumptions:

  1. Cognitive biases are systematic, not random — they create directional price effects
  2. Limits to arbitrage prevent rational traders from fully correcting mispricings
  3. Reference points and framing significantly affect decisions

Methodology

Step 1 — Identify the Behavioral Anomaly

Observe the pricing pattern or decision that deviates from rational expectations.

Step 2 — Map to Specific Biases

Bias Description Market Effect
Loss aversion Losses hurt ~2x more than equivalent gains Disposition effect, equity premium puzzle
Overconfidence Overestimate precision of private information Excessive trading, under-diversification
Herding Follow the crowd regardless of private signal Bubbles, momentum, crashes
Anchoring Over-rely on initial reference points Under-reaction to earnings surprises
Mental accounting Treat money differently based on source/label Portfolio segregation, house-money effect
