This sustained concentration in mega-cap leadership often aligns with stronger cross-asset risk appetite and has coincided with higher stock and crypto co-movement in past episodes of equity momentum or stress (source: IMF 2022). For trading, monitor BTC and ETH for correlation-driven moves around US equity sessions when mega-cap momentum is elevated, as prior IMF research documented tighter co-movements between cryptocurrencies and US equities during both risk-on and risk-off periods (source: IMF 2022).
