I just love the title of this paper…

A job market paper for a PhD student (Jane Zhao) who was on the market a few years ago.

Quant Jocks and Tire Kickers: Does the Stock Selection Process Matter?

This paper classifies mutual funds into two groups according to their distinctive stock selection approaches: tire kickers who rely on fund managers’ personal judgment and fundamental analysis to pick stocks, and quant jocks who use computer-based models to select stocks. I examine how the stock selection approach affects mutual fund performance and economies of scale. I document an increasing trend of quantitative techniques used by mutual funds, and some unique characteristics of quant jocks. Quant jocks and tire kickers have similar factor-adjusted alphas, but quant jocks have higher Sharpe ratios. Quant jocks tend to be much smaller than tire kickers. I explore possible explanations for the size difference. I find that although quant jocks can cheaply screen a large universe of stocks, the stocks that quant jocks invest in are smaller and less liquid, which results in higher transaction costs and limited scalability of quantitative investment strategies.
