In latest months, Bitcoin has adopted a sample that’s frustratingly acquainted to bulls. When the Nasdaq 100 inventory index falls, it seems to be overly correlated with the Nasdaq 100, however when the main tech indexes rise, nearly all correlation disappears.
This week was no exception, with the Nasdaq falling 2% on Thursday and Bitcoin plummeting twice as a lot. Tech shares then noticed modest positive aspects on Friday, however they fell in need of Bitcoin.
Heading into the ultimate six weeks of 2025, the Nasdaq 100 is at present up 20% year-to-date, whereas Bitcoin is up simply 3%.
Reflection of asymmetry
What's taking place is that the correlation with the Nasdaq 100 shouldn’t be gone, and the Nasdaq 100 remains to be at a excessive degree of round 0.8, in keeping with a report from Wintermute's Jasper de Meere this week.
“This displays not a breakdown in correlation, however an asymmetry, or the unevenness of how Bitcoin responds to threat,” Demere mentioned. “When inventory costs rise, BTC reacts much less. When inventory costs fall, BTC tends to maneuver extra sharply in the identical route.”
De Meere measures this by “efficiency skew,” with a “optimistic skew” indicating Bitcoin outperforming in a risk-on surroundings and a “damaging skew” indicating Bitcoin lagging in a risk-off surroundings.
This could come as no shock to anybody who has been listening to the truth that skew has been firmly damaging for a while.
Making an attempt to place some numbers on it, Da Maere graphed the share of days on which BTC had a optimistic efficiency bias versus the Nasdaq on a 365-day rolling foundation.
What he discovered is that shares have fallen to ranges not seen for the reason that backside of the final main bear market in late 2022.

Damaging skew reaches ranges in late 2022 (Wintermute)
Why is it so unhealthy? Da Mehle means that Bitcoin is dropping mindshare as a result of the speculative urge for food of each institutional buyers and people is sufficiently glad in equities. There are additionally liquidity points, as ETF inflows have slowed, stablecoin issuance has peaked, and total market depth throughout exchanges stays beneath its degree originally of 2024.
hopeful outlook
“Traditionally, one of these damaging asymmetry seems not close to the highest, however quite close to the underside,” Da Mehle concluded. “When BTC inventory value falls extra on unhealthy days than it rises on good days, it often signifies fatigue quite than power.”
“The present BTC/NASDAQ efficiency bias means that BTC buyers are considerably exhausted and can stay so for a while.”
