ARB in plain facts
Updated 2026-11-14 (UTC) · Binance spot data
How ARB behaves versus Bitcoin
ARB has a beta of 1.29 against Bitcoin: largely moves in step with Bitcoin (~1.29×). In plain terms, on a day Bitcoin moves 1%, ARB has moved about 1.29% on average in the same direction. Beta describes past co-movement over the available daily history; it is not a forecast.
What ARB moves with
Over the last 90 days its daily moves tracked UNI (0.67) and BNB (0.64) most closely among the large coins we compare against. A correlation of 1.0 would mean they moved in lockstep; 0 would mean no relationship.
Where ARB sits in its own history
Today's price is higher than on 16% of the days in its last 4 years on Binance — low in its range — closer to past lows than past peaks.
How volatile ARB is
Its annualised volatility over the last 90 days is 148.3%, about 3.44× Bitcoin's over the same window. Today's move: a typical day (~1.2× normal).
ARB's worst drawdown
The deepest peak-to-trough fall in this window was -96.8%, bottoming on 2026-08-15. Context: an extraordinary market period (no single event matched). This number is free on Sightglass and always will be.
