$BTC is underperforming the S&P 500 on 2 out of 3 trading days. However, when BTC does outperform, the excess returns (green) are significantly larger. Also noteworthy is that these excess returns have been slowly degrading over the years.
AI visual note: A Glassnode chart titled "Bitcoin's Bursts of Outperformance Are Shrinking Cycle by Cycle" compares BTC Price (orange, +614%) against the S&P 500 (blue, +130%) from January 2021 through early 2026, with a lower panel showing 90-session excess return in basis points—highlighting diminishing peaks from +379bp in 2021 down to +76bp in 2025 and a current -30.3bp. The visualization supports the post's observation that BTC's excess return bursts over the S&P 500 have been steadily degrading across cycles, even as BTC's overall long-term performance still strongly outpaces the index.
