"There are tons of people who are late to trends by nature and adopt a trend after it's no longer in fashion. They exist in mutual funds. They exist in clothes. They exist in cars. They exist in lifestyles"

This quote by Jim Cramer is describing the fact that there are many people who are late to trends and embrace them after they are no longer in style. He is saying that this phenomenon is not limited to just one area, but can be seen in many different elements of life. For example, he points out shared funds, clothing, automobiles, and lifestyles. This is likely describing individuals who purchase mutual funds after the marketplace has already increased, buy clothes that are no longer in style, purchase automobiles that are no longer popular, and embrace way of lives that are no longer stylish. Cramer is emphasizing that this is a common event which it can be seen in many different locations.
