"Information Leakage from Short Sellers" (NBER WP) with Bruno Giovannetti and Bernard Herskovic. Revise and resubmit at the Journal of Finance.
Broker's equity lending desks have a privileged position: they talk every day to short-sellers in the over-the-counter lending market. Consistent with prior evidence showing information leakage by financial intermediaries, we find that clients from brokers that are connected to informed short-sellers trade in the same direction and benefit from short-seller's superior information.

"The overpricing of popular high-risk stocks" with Bruno Giovannetti and Bernardo Guimarães. Revise and resubmit at the Review of Asset Pricing Studies.
There is solid evidence showing that retail investors end up holding stocks with falling prices. This is the result of a combination of several behaviors: contrarian investing, preference for distressed stocks, preference for lottery like-stocks and the disposition effect. In this paper, we use detailed data to discipline (i) a reduced-form contrarian retail demand and (ii) an equation that limits arbitrageurs. Then, we show that (i) and (ii) can produce severe overpricing of popular high-risk stocks.

"Counting pennies, losing pounds: biased learning about own trading ability" with Bruno Giovannetti, Bernardo Guimarães and Bernardo Maciel.
To answer this question, we examine how losing day traders decide to quit. Using detailed id-level data from the Brazilian futures and equity markets from 2012 to 2018, we find that day traders look at the proportion of profitable daytrading days to decide when to quit and not to the their actual accumulated financial loss. This surprising behavior is also problematic, as the proportion of profitable days can be inadvertently inflated by the individuals’ disposition effect and give the impression of superior performance. Indeed, we find that those day traders who persist the most exhibit a stronger disposition effect; their daily losses tend to be much larger than their daily gains, but their proportion of profitable days is well above 50%.

"Familiarity Breeds Day Trade" with Bruno Giovannetti and Guilherme Paiva.
Individuals over-invest in familiar stocks. We document the existence of familiarity bias also in day trade, a trading activity that lasts hours at most. Living close to a brick-and-mortar firm's local store in a small city more than doubles the likelihood of an individual day-trading its stock. Information, the usual explanation for the familiarity bias, is unlikely to explain our finding: a single local store in a small city could give useful information for day-trading only in truly abnormal events.

"Day trading for a Living?" with Rodrigo De-Losso and Bruno Giovannetti.
Can one make a living day trading stocks? In this short note, we hope to inform retail investors who are thinking about leaving their jobs and become day traders. We base our evidence using high-quality data from the entire universe of Brazilian retail investors who decided to do just that.

"Attention and Biases: Evidence from Tax-inattentive Investors" with Justin Birru, Rodrigo De-Losso and Bruno Giovannetti. Forthcoming at Management Science.
Are some investors prone to behavioral biases? We find that retail investors who forget to take advantage of a simple and widely known tax break opportunity in Brazil are also more prone to biases. Importantly, our results hold even after controlling for a large number of investor sophistication measures such as trading longevity, professional occupation, and whether the investor has traded derivatives or sold short stocks in the past. Our results support theories that relate investor's inherent inattention to behavioral biases.

"US Risk Premia under Emerging Markets Constraints" with Elias Cavalcante, Rodrigo De-Losso, Bruno Giovannetti. Journal of Empirical Finance. Volume 67, June, 2022. Pages 217-230.
Some claim that there is no equity risk premium in Brazil; they arrive at such conclusion after looking at stock returns and risk-free rates from the mid 1990's until now. We argue that if we imposed the same data limitation to the US, we could arrive at the same puzzling result. Conclusion: if you want to use realized returns to infer the size of the Brazilian equity risk premium, you better wait a couple more years...
"Price transparency in OTC equity lending markets: Evidence from a loan fee benchmark" with Fábio Cereda, Rodrigo De-Losso, Alan Genaro, Bruno Giovannetti. Journal of Financial Economics. Volume 143, January, 2022. Pages 569-592.
Short-sellers are informed investors who make prices more efficient. However, they are restricted by the frictions in the equity lending market; the equity lending market is an over-the-counter markets with opaque prices (i.e. loan fees). We explore a transparency shock that took place in the Brazilian equity lending market in March, 2011, to show that a less opaque equity lending market results in more trading volume, lower loan fees, and improved stock price efficiency. We conclude by suggesting regulators to adopt "loan-fee benchmarks" as an effective way of improving transparency in equity lending markets worldwide.
"The short-selling skill of institutions and individuals" with Rodrigo De-Losso and Bruno Giovannetti. Journal of Banking & Finance. Volume 101, April, 2019. Pages 77–91. (internet appendix).
Aggregate short-selling predicts future returns, but what can we say about individual short-sellers? Relying on individual trading data on both opening and closing of lending positions by all Brazilian short-sellers, we find that 30% of short-selling volume comes from investors who are able to profit consistently. The evidence of superior performance is consistent out-of-sample (both over time and across stocks), an indication of skill. Finally, we examine what the skilled short-sellers do different; among other things, they are more likely to pick already losing stocks (i.e., momentum investors) as opposed to correcting overpricings.
"Well-Connected short-sellers pay lower loan fees: a Market-wide analysis" with Rodrigo De-Losso, Alan De Genaro, and Bruno Giovannetti. Journal of Financial Economics, Volume 123, March, 2017. Pages 646–670.
Short-sellers have to borrow the stock they want to sell short in the equity lending market, an over-the-counter market. The price they will pay to borrow the stock is not clear, however. We show that those short-sellers who are well connected to brokers, who in turn are well connected to lenders, are able to pay lower loan fees. Our results are consistent with search costs being an important source of price variation in opaque markets.

"Forecasting the brazilian yield curve using forward-looking variables" with Fausto Araújo and Marcelo Fernandes. International Journal of Forecasting, Volume 33, Issue 1, 2017. Pages 121–131.
We estimate an augmented VAR model for a system that includes not only the Nelson–Siegel factors of the Brazilian yield curve, but also the principal components of a large number of macroeconomic and financial indicators. The main finding is that forward-looking variables, such as market expectations about inflation and GDP, are crucial to improve short-term forecasts of the yield curve.
"Short-sellers: informed but restricted" with Rodrigo De-Losso, Alan De Genaro, and Bruno Giovannetti. Journal of International Money and Finance, Volume 47, October 2014, Pages 56–70.
In a single regression, we test the two main hypothesis concerning short-sellers: (H1) short-sellers are informed investors and their trading activity predicts lower stock prices; (H2) when short-sellers face restrictions and there is dispersion of opinion, stocks become overpriced. We find that both are true: short-sellers are informed but at times restricted.
