LatAm Research "Crowded Stocks: Quantitative Insights on LatAm – May 202..."
It is interesting to compare how long-/short-crowding data differ from sector
loading. To analyze that, we only use stocks covered by UBS from the Brazilian Stock
Exchange as a reference. We have imposed no restrictions, so based on our previous
assumptions, we would anticipate crowding to possibly be more apparent in some

May, Financials and Energy were able to keep their long-held position. Coming next,
Materials stands in the third place. Put together, the above-mentioned sectors have
dominated the picture over time – a direct consequence of the large market shares
of O&G/mining giants Petrobras and Vale, further enhanced by Brazilian banks.

degree of variability. In May, Consumer Discretionary had an upward trend, while
Consumer Staples, Communication Services Utilities lost ground during the month.
