Goldman Sachs announced a new product called Marcus Invest on Tuesday, a low-cost digital investment platform much like the robo-advisors that have emerged in the last 10 years. The product joins the bank’s other Marcus consumer-facing products, which include bank accounts and personal loans.

At first glance, the new product seems to piggyback on the unprecedented interest in stocks following the l’affaire GameStop, in which the power of social media helped drive up a sleepy stock from the teens to almost $400 before it fell back down again.

But there’s one big difference that represents a big gamble for the firm: You can’t buy individual stocks through Marcus Invest.

Last year was the biggest ever for people signing up for new brokerage accounts thanks to free trading on platforms like Robinhood. But 2021 might eclipse 2020 in terms of new investors coming into the market: more people have googled “how to buy stocks” in the last week of January than ever before.

Marcus (“by Goldman”) and its new product may look as if it’s jumping on the bandwagon to try to woo these new investors, but the inability to trade stocks with it means it’s a completely different type of offering than Robinhood and its more established competitors like Schwab, TD Ameritrade, Interactive Brokers, and the like. Instead, Goldman is going with a more robo-advisor and automated type of investing, letting allocation of a managed basket of asset classes represented by ETFs be the differentiating factor rather than trying to pick winning stocks.

The managed basket of index funds and ETFs is already becoming “best practice” for a lot in the financial industry: you diversify and invest with a handful of funds that provide exposure to U.S. large-cap stocks, emerging markets, foreign stocks, corporate bonds, or whatever you need. It does not involve picking individual stocks.

Investing is a problem that has been ‘solved’

This has grown into accepted conventional investing wisdom in the money management world. Scores of wealth management firms focus on allocation and use ETFs and index funds as their primary tools, rather than stock picking.

“People are historically not great stock pickers,” Ritholtz Wealth Management’s Barry Ritholtz told Yahoo Finance. “The data overwhelmingly shows that most people do not add any value in their stock selection.” Ritholtz’s firm is a strong advocate of asset class investing. If you have the compulsion to defy the odds and buy stocks, just keep it a small percentage of your overall portfolio and be okay losing it all.
