Expert writing Tips

Best practice

Use "all-time high" to emphasize that a value is the highest it has ever been, compared to any point in the past. Ensure the context clearly defines the period being considered. For instance, "the stock market reached an "all-time high" in 2025".

Common error

Avoid using "all-time high" without clarifying the period under consideration. For example, saying "sales are at an "all-time high"" is vague; instead, specify "sales are at an "all-time high" for this quarter".
