What to Check

Check whether the signal is a measurable indicator, investor narrative, media description, trading rule, or hindsight explanation. Sentiment is context, not a standalone forecast.

Common Mistakes

  • Using sentiment as a precise forecast.
  • Confusing a narrative with a repeatable investment rule.
  • Ignoring valuation, liquidity, and risk controls during crowded trades.
  • Explaining outcomes with hindsight instead of documented decision evidence.
