Sabedoria do Robinhood

 Resumo:

Robinhood investors increased their holdings in the March 2020 COVID bear market, indicating an absence of collective panic and margin calls. This steadfastness was rewarded in the subsequent bull market. Despite unusual interest in some “experience” stocks (e.g., cannabis stocks), they tilted primarily towards stocks with high past share volume and dollar-trading volume (themselves mostly big stocks). From mid-2018 to mid-2020, an aggregated crowd consensus portfolio (a proxy for the household-equal-weighted portfolio) had both good timing and good alpha.
