Just over half of high net worth Americans, those with investment portfolios of $1 million or more, invest in their hobbies, according to BMO private bank research. Passion investing can diversify a portfolio to a degree, but most hobby investors (62%) do it because it's "fun."

"People who choose to invest in their hobbies often do so because it allows them to feel a sense of engagement without having to spend a lot of time on them.
