One of the worst and weirdest investment tips is to invest in companies you use, know or like in your personal life.
There’s simply no reason to believe this is a good strategy.
Your favourite brand could easily be a terrible business. Or could be overvalued already. Or could be in structural decline.
Just because you use a Samsung doesn’t mean it’s a better investment than Apple. Just because you drive a GM doesn’t make it a better investment than Ford. Just because you bank at TD doesn’t mean it’s a better investment than any of the other banks.
Investing based on your personal experience with companies will lead you to make risky bets, likely concentrated in specific sectors, with no rhyme or reason to why.
It is not an evidence-based strategy and there’s no reason to believe it will lead to good returns. It’s a piece of investment advice that needs to die.
