Marc Gerstein

Marc Gerstein is an unconventional "quant." He has long specialized in rules- and factor-based equity-investing strategies. And he authored two books on stock screening – Screening the Market and The Value Connection. Marc's quant inclinations trace back to his early days as an attorney (mainly criminal and landlord-tenant proceedings). In that world, everything Marc did had to be supported by evidence or legal authority. He first applied this evidence-oriented approach at Value Line, an independent investment-research firm that he joined in 1980. There, he learned to relate human investment stories to that company's "Timeliness" ranking system. During the mid-1980s, Marc managed the Value Line Aggressive Income Trust. That's a high-yield ("junk") bond open-end mutual fund. He steered the fund through the Drexel Burnham scandals and the related junk-bond storms. He came away from that experience with a non-academic but highly reality-based understanding of risk.

Forget the Stock Market
