DAY TRADE: across the statistics | DAY TRADE: do outro lado das estatisticas
This paper questions some current ideas about the practice of specific capital market operations - the so-called day trading operations. The text advanced from theoretical propositions to a detailed analysis of the study entitled "Is it possible to live by day-trading?" (CHAGUE and GIOVANNETTI, 2019), to which it offers a counterpoint. This investigation reveal the existence of important elements that are not yet properly weighed in the treatment of the current theme, leading to loss of dimensions that are - or should be - inseparable from this type of research. The conclusion reached is that the existing scientific evidence does not show that the adoption of the day trade as an occupation is economically unsustainable, nor does it prove the impossibility of evolution of the day traders' operational performance over time. ----- O presente trabalho coloca em questionamento algumas ideias atualmente difundidas sobre a pratica de operacoes especificas do mercado de capitais - as chamadas operacoes day trade. Partindo de proposicoes teoricas, o texto avanca a uma analise detalhada do estudo intitulado "E possivel viver de day-trading?" (CHAGUE e GIOVANNETTI, 2019), ao qual oferece contraponto. Essa investigacao revela a existencia de importantes elementos que ainda nao estao devidamente sopesados no tratamento do tema em voga, acarretando perda de dimensoes que sao - ou deveriam ser - indissociaveis desse tipo de pesquisa. A conclusao alcancada e de que as evidencias cientificas ate entao existentes nao demonstram que a adocao do day trade como profissao seja insustentavel economicamente, nem comprovam a impossibilidade de evolucao da performance operacional dos day traders ao longo do tempo.
