it peaks
Grammar usage guide and real-world examplesUSAGE SUMMARY
The phrase "it peaks" is not a complete sentence and therefore is not correct to use on its own in written English.
It may be a part of a complete sentence, but it would still require other words and phrases to make sense. For example, you could say "The stock market reaches its peak," where "it peaks" is used as a verb phrase to describe the action of reaching the highest point. In this case, "it" refers to the stock market.
