Percent Below All-Time High

This figure divides the current price by the all-time high and expresses the shortfall as a percentage. It is the most widely quoted framing of where an asset stands relative to its own history. Its entire meaning depends on the quality of the single print that set the high.

计算方式

(price / all-time high - 1) x 100

易产生误导之处

The measure is fixed to one observation in the entire history, so an erroneous or extremely thin print sets the reference permanently and no later market activity corrects it. Two assets showing the same percentage below their highs can be in completely different situations: one set its high years ago under a different supply schedule, the other last month. Where a token migrated contracts or redenominated, the historical high is not measured in the same unit as the current price, making the percentage arithmetic invalid. It also ignores staking rewards, airdrops, and fork distributions, so it overstates the shortfall for a position that accrued any of those.

与股权的类比，以及为何该类比不成立

Percentage below the 52-week or all-time high in equities; equity figures are computed on split- and dividend-adjusted series, while this one is a raw price comparison across possibly incompatible units.

如何解读高值或低值

A larger percentage means the last traded price is further beneath the highest price ever recorded. It describes distance from a past observation and contains nothing about future prices or about whether that past high was itself representative.
