In the late nineties he changed direction and moved into sell-side quant research, building asset allocation models for buy-side clients. After his firm completed a merger, he left to join the founding team at StarMine, an early fintech startup that used quant methods to measure the accuracy of sell-side equity research analysts.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">In 2005 he moved on to a prop trading group at Merrill Lynch, where he managed several internal portfolios, then went on to develop quant strategies for Morgan Stanley\u2019s Process Driven Trading (PDT).<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">&#8220;Right after I joined Morgan Stanley in August 2007, we had what was called at the time the &#8216;quant quake.&#8217; A lot of strategies, including ours, blew up without warning. When the dust cleared, it turned out we were all trading similar assets and using similar strategies.&#8221;<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">That got Vinesh&#8217;s attention.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">&#8220;The trouble was that nearly all of us were using the same data \u2013 price, earnings estimates, and balance sheet\/income statements. Because of that, when someone started liquidating, it blew up pretty much everyone else&#8217;s book. The positive was that it opened our eyes to the world of untapped data sitting out there ready to be explored, to inform more diverse strategies.&#8221;<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Vinesh left PDT to start ExtractAlpha. And some years later, in 2021, ExtractAlpha acquired the firm that is our subject here: Estimize.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">&#8220;The Estimize model applies the conceptual framework of crowdsourcing to earnings estimates. The structure is that you, me, or anyone else can come up with an estimate for a company&#8217;s results and contribute it to our database. Our job is to aggregate it, compare it to what the Street analysts are saying, and report that out.&#8221;<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Jha cites Galton&#8217;s ox, the foundational experiment that established the concept of the &#8216;wisdom of crowds.&#8217; In 1907, England&#8217;s Sir Francis Galton asked 787 villagers to guess the weight of an ox. None of them got the right answer, but when Galton averaged their guesses, the estimate was nearly perfect.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">&#8220;It&#8217;s really like that. If you average out everyone&#8217;s viewpoints \u2013 including non-professionals \u2013 you get to something better than you would if you just took a small group of professionals.&#8221;<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">But collecting estimates from non-professionals is a very different game from getting a data feed from a well-regarded broker. Non-professionals need encouragement.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">&#8220;Buy-side investors and portfolio managers have always had a community. They huddle together, call each other privately, exchange estimates \u2013 &#8216;I think the sell side is too low on this, what do you think,&#8217; and so on. With non-professionals, we had to build a new community within the platform, starting from the ground up. So, we used incentives and gamification.&#8221;<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">One of the more innovative examples of gamification is what Jha calls &#8220;the shaming algorithm.&#8221;<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">&#8220;It was a little controversial in-house,&#8221; he says, smiling, &#8220;but it works. It doesn&#8217;t stop anyone from putting in a safe estimate, but it&#8217;ll be, like, you sure you don&#8217;t want to be a little different here? Take a bolder view? It discourages people from being lazy, discourages them from staying on the platform unless they&#8217;re committed. As expected, when we put it in a lot of contributors dropped off. But that was a good thing because the ones who stayed were the ones we wanted: they were engaged.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">\u201cOur estimates are more accurate than the professionals. That&#8217;s been confirmed by academics.\u201d (<a href=\"https:\/\/link.springer.com\/article\/10.1007\/s11408-024-00447-4\">Herding the crowds: how sentiment affects crowdsourced earnings estimates
