Behavioral finance expert: This ‘powerful mental trick’ can make you a better investor

If you follow financial accounts on social media, your timeline is likely crowded with people touting the next big winning investment. “Buy our favorite stock or cryptocurrency now, before it goes to the moon,” they tell you.

What’s more, even most active mutual fund managers have trouble consistently outperforming their benchmark indexes.
