Introdução

Esta página fornece uma análise abrangente do histórico conhecido de negociações internas de Morgan W Davis. Insiders são oficiais, diretores ou investidores significativos em uma empresa. É ilegal para insiders realizarem negociações em suas próprias empresas baseados em informações específicas, não públicas. Isso não significa que seja ilegal para eles realizarem qualquer negociação em suas próprias empresas. No entanto, eles devem reportar todas as negociações à SEC através de um Formulário 4. Apesar dessas restrições, pesquisas acadêmicas sugerem que insiders - em geral - tendem a superar o mercado em suas próprias empresas.

Rentabilidade Média de Negociação

A rentabilidade média de negociação é o retorno médio de todas as compras de mercado abertas feitas pelo insider nos últimos três anos. Para calcular isso, examinamos cada compra de mercado aberto, não planejada, feita pelo insider, excluindo todas as negociações que foram marcadas como parte de um plano de negociação 10b5-1. Em seguida, calculamos o desempenho médio dessas negociações ao longo de 3, 6 e 12 meses, fazendo a média de cada uma dessas durações para gerar uma métrica de desempenho final para cada negociação. Finalmente, fazemos a média de todas as métricas de desempenho para calcular uma métrica de desempenho para o insider. Esta lista inclui apenas insiders que fizeram pelo menos três negociações nos últimos dois anos.

Se a rentabilidade de negociação deste insider é "N/A", então o insider ou não fez quaisquer compras de mercado aberto nos últimos três anos, ou as negociações que eles fizeram são muito recentes para calcular uma métrica de desempenho confiável.

Como Interpretar os Gráficos

Os gráficos a seguir mostram o desempenho das ações dos a ativos ubsequentes a cada transação de mercado aberto, não planejada feita por Morgan W Davis. Transações não planejadas são negociações que não foram feitas como parte de um plano de negociação 10b5-1. O desempenho das ações é representado como mudança percentual cumulativa no preço das ações. Por exemplo, se uma transação interna foi feita em 1 de janeiro de 2019, o gráfico mostrará a mudança percentual diária da segurança até o dia presente. Se o preço da ação passasse de $10 para $15 durante este período, a mudança percentual cumulativa no preço das ações seria de 50%. Uma mudança no preço de $10 para $20 seria de 100%, e uma mudança no preço de $10 para $5 seria de -50%.

Ultimamente, estamos tentando determinar quão estreitamente as negociações do interno correlacionam-se a retornos excessivos (positivos ou negativos) no preço da ação para ver se o interno está cronometrando suas transações para lucrar com informações internas. Considere a situação onde um interno estava fazendo isso. Nesta situação, esperaríamos (a) retornos positivos após compras, ou (b) retornos negativos após vendas. No caso de (a), o gráfico de COMPRA mostraria uma série de curvas ascendentes, indicando retornos positivos após cada transação de compra. No caso de (b), o gráfico de VENDA mostraria uma série de curvas descendentes, indicando retornos negativos após cada transação de venda.

No entanto, isso sozinho não é suficiente para tirar conclusões. Se, por exemplo, o preço da ação da empresa estivesse em uma escalada não cíclica ao longo de muitos anos, então esperaríamos que todos os gráficos pós-compra tivessem uma inclinação ascendente. Da mesma forma, declínios não cíclicos ao longo de muitos anos resultariam em gráficos pós-negociação inclinados para baixo. Nenhum desses gráficos sugeriria atividade de negociação interna.

O indicador mais forte seria uma situação em que o preço da ação fosse extremamente cíclico, e houvesse sinais positivos no gráfico de COMPRA e gráficos negativos no gráfico de VENDA. Esta situação seria altamente sugestiva de um interno que estava cronometrando transações para sua vantagem financeira.
