Coin B can also be down 30%, however its worth is everywhere, going up and down by massive percentages day by day. If we glance solely on the drop from the highest, each cash look equally “low cost.”
An expert investor would look past the value drop and think about the risk-adjusted return.
On this case, A’s smoothest worth path would possibly give it a Sharpe ratio of, say, 1.5, whereas forex B’s wild swings depart it with a Sharpe ratio of simply 0.5. So though each have the identical 30% drawdown, Coin A clearly outperforms per unit of danger, making it the extra engaging possibility for sizing a place.
Historic context

Traditionally, each time the annual risk-adjusted return has reached this stage of “unattractiveness,” it has marked the purpose of most vendor exhaustion.
