NEW YORK (TheStreet) -- Executive Vice President Naureen Hassan says Schwab's (SCHW) - Get Report Intelligent Portfolio investors are split evenly among GenX Millennials and Boomers who adapted to online accessibility. She added that about 65% of new investors in the program are under 45 years old.

Hassan said Schwab's new automated investing service garnered over $2.2 billion in assets since the March launch in more than 30,000 accounts.

A big reason for its success is that many clients found it hard on their own to get into high-quality funds and portfolios. Within minutes, she said, investors can get into a high-quality portfolio. Once they're in, the system will re-balance.

Hassan said the service offers a wide range of options including 20 asset classes, 54 exchange-traded funds and 11 fund families. If investors want someone to advise them, that's available, too.

For those who want to build a diversified portfolio and stay on track, this is a great option, Hassan said. If an investor wants to get more customized in their portfolio holdings, they can talk to a person at Schwab.
