Percent off all-time high is a financial term that refers to the percentage difference between the current trading price of a stock or other financial instrument and its all-time high price expressed in percentage value. It is calculated by subtracting the all-time high price from the current price, dividing the result by the all-time high price, and then multiplying by 100 to get a percentage value.
Let’s say APPLE stock has an all-time high price of $180 and its current trading price is $148, then the percent off all-time high would be calculated as follows:
Percent off all-time high = ((180 - 148) / 180) x 100 = 18%
This means that the stock is currently trading at a price that is 18% lower than its all-time high.
High level of percent off all-time high may suggest that a stock is undervalued and may present a buying opportunity, while a low level of percent off all-time high may suggest that a stock is overvalued and may present a selling opportunity.
