noun | all-time high
The highest price that a stock, crypto, or other asset has ever reached. Hitting an ATH is like reaching the top of Mount Everest - it's a big deal, and everyone wants to plant their flag there. But what goes up must come down, so don't get too cocky!
Example
"Bitcoin just hit an ATH of $60,000! To the moon, baby!"
"I bought Tesla stock at the ATH, and now I'm crying into my avocado toast as the price tanks."
"XYZ Corp just reported record profits, so expect their stock to moon and hit a new ATH!"
