Using a novel measure of stock-level trade imitation, we uncover "smart" copycats: fund managers that use their own information when beneficial, and otherwise imitate other managers' better trades. Contrary to previous research, we find that these partial imitation strategies lead to...

The trading app Robinhood maintains a list of the 100 stocks most widely held by its users. Using a novel dataset of stock popularity with Robinhood user, I focus on new securities that enter the list. I document the strong effect that salience of new Top 100 listing events has on the attention...

We introduce a novel methodology to identify copycat behavior in mutual funds. We find that imitation is pervasive in the mutual fund industry. While most copycats underperform, a small number are 'smart imitators'. We find that funds at the high and low ends of the Copycat Score range...

We look at the relationship between religion and innovation at the country level. Innovation is captured by the Global Innovation Index and certain innovation outputs. Religiosity is measured across 141 countries in terms of religious belonging, belief, and intolerance. In addition, we look at...

I investigate whether mutual fund manager possess superior stock picking skills, by comparing the performance of stocks they hold in their portfolios versus that of stocks which they do not hold. In particular, I focus on a class of assets identified as "Lottery Stocks". These are stocks with...

I investigate the relationship between measures of skewness and expected stock returns. Forcing the data to fit a linear model, past research finds only a negative relationship between these variables. Using a novel methodology that endogenously estimates breakpoints in the relationship between...

We theoretically establish a market microstructure bias embedded in the estimate of industry-adjusted idiosyncratic variance and empirically show that the bid-ask spread eliminates the observed time trend in aggregate idiosyncratic variance (Campbell, Lettau, Malkiel, and Xu, 2001). These...

After building up foreign currency denominated (FC) liabilities over several years, Colombian firms might be vulnerable to a shift in external conditions. We undertake three empirical exercises to better understand these vulnerabilities. First, we identify the determinants of FC borrowing....
