What It Is

Nikkei 225 daily close-to-close log returns (FRED NIKKEI225, 1949+). Japan-market analog of the S&P series; similar heavy-tailed structure.

Interpretation

Standard analysis sees: heavy-tailed; left-skewed; aperiodic / broadband; high-complexity (noise-like); time-irreversible (sharp rises, slow decay). The atlas finds no named structure, but the source is distinctively extreme on Nonstationarity:ac1_trend (-3.3z) — beyond what the standard bank predicts for it.
