The world’s largest investment firm wants to help everyday investors think like quants.

BlackRock Inc. is now offering a free online tool that allows users to analyze 2,400 equity-mutual funds and exchange-traded funds through the lens of “factors,” or traits that data-driven traders rely on to drive returns. Factors include volatility, size and value.

With its Factor Box, BlackRock aims to illuminate investors about this increasingly popular strategy. The firm estimates that by 2022 the factor industry’s assets under management will expand to $3.4 trillion from $1.9 trillion in 2017.

First publicized by researchers in the 1960s, factor-based investing has proliferated recently through smart-beta ETFs, which apply rules to create indexes of stocks based on traits like momentum or value. Assets of U.S.-listed smart beta ETFs have grown to over $709 billion, according to Bloomberg data.

Andrew Ang, BlackRock’s head of factor-based strategies, said Factor Box is a more comprehensive version of Morningstar Inc.’s Style Box -- an investing tool that’s guided a generation of investors.

Users of BlackRock’s tool will need to buy into the firm’s definition of factors, which are not universally agreed upon. For instance, it doesn’t separate out sustainability as a factor, while some see environmental, social and governance behavior as its own category.
