Dr. Jordan Grummitt identifies overconfidence and the pursuit of 'alpha' as common pitfalls for young do-it-yourself (DIY) investors. He warns against concentrating risk in the stock market beyond professional capabilities, advising that focusing on beta and index investing is generally more prudent for most individuals.
“So the truth of the matter is, when you are young and you're in the accumulation phase, it's almost hard to mess up, right. You have to do it, Nickma Julie says, just keep buying, and so when we're young, there's lots of room for airs.”
“So over confident people seek alpha, right, They're saying, boy, I don't want to just take what the market has to give me beta, but I'm going to seek alpha and that's exceedingly hard.”
“I think that in the young investors it's definitely an overconfidence issue. And again we talked about this a little bit. It's the seeking alpha when they should be concentrating on beta.”
