Marcus by Goldman Sachs on Tuesday unveiled Marcus Invest, a robo-advisory tool for which the bank developed automatic portfolio management and rebalancing technology. Marcus is the online consumer banking business born out of the Wall Street incumbent in 2016.

Marcus Invest is a new digital investment platform that offers managed portfolios of stock and bond ETFs, automatically spinning up investment portfolio recommendations for consumers, based on risk tolerance, time horizon and investment strategy. The platform also offers automated daily portfolio management and rebalancing, which is the periodic aligning of the customer’s account to match the customer’s investment goals, according to Andrea Finan, head of digital investing at Marcus.

During product development and testing, Marcus engaged with thousands of individuals — including existing customers, corporate partnership clients and mass affluent prospects — through surveys, focus groups and user testing, Finan said. There was an internal employee beta program, too, during which a few hundred staffers participated to give feedback on marketing language, user experience and design.

The Digital Investing and Advice team of software engineers, product managers and designers developed technology to automatically monitor portfolios as the market fluctuates, Finan said. Shifts in market prices or inflows and outflows from a customer’s account, such as deposits and withdrawals, may change the account’s asset allocation, she said. To ensure asset allocation stays on target, the Marcus Invest team regularly monitors the portfolio and rebalances account holdings.

However, Marcus is not leaving everything up to the automated rebalancing function. Rebalancing can be overridden by investment advisory personnel if it were to negatively impact accounts, Finan added, such as during volatile market conditions. The automated recommended trades are reviewed and approved by human portfolio managers, although, rebalancing appears to customers as automatic. An account must be opened with a minimum of $1,000 and, through an integration with Plaid, customers can transfer funds into and out of Marcus Invest from both internal and external bank accounts, Finan said.

“We heard from our existing customers that they were interested in investing products from Marcus,” Finan said. “We designed Marcus Invest to help take on some of the difficult and time-consuming elements of investing on your own.”

Marcus Invest, which is slated for a U.K. launch by yearend, joins a crowded field of consumer-facing automated investing providers, including Stash, Betterment and Wealthfront, which continues to build out its integrations to speed money movement. However, Goldman Sachs is betting on its 150-year history of providing financial expertise to set the tool apart.
