All-Time High (ATH)

The all-time high is measured from when the asset first starts trading on an exchange, and changes whenever the most recent record high is exceeded. The value of an all-time high is usually nominal, meaning inflation is not accounted for.

All-time highs typically represent significant price news for markets. Investors may be motivated to purchase stock believing the company or asset will continue to perform well in the future. Other investors may be persuaded to sell, believing that the price may trend downwards in the future. Assets that constantly reach all-time highs rapidly attract prospective investors, while those that repeatedly hit record lows dissuade potential investors.
