Data & methodology
How are green, red, and flat days defined?
- We use dividend-adjusted (or close-to-close for non-equity) daily returns. Green: return ≥ +0.01%. Red: return ≤ −0.01%. Flat: between those bounds.
How is the current streak calculated?
- We count consecutive green or consecutive red days using the same thresholds. If the most recent session is flat, we skip trailing flat days and measure from the last non-flat close.
What does “vs S&P 500” mean?
- On sessions where the S&P 500 (^GSPC) was green, we report how often this stock was also green. Shown only for USD equities when benchmark data exists and the symbol is not the index itself.
Where does the archetype come from?
- Sample standard deviation of daily returns: low → Steady, high → Explosive, otherwise Balanced. Labels describe typical daily volatility, not quality of the investment.
