Here are the stocks seeing a bias toward call activity on Thursday. This filtered scan is based on the International Securities Exchange (ISE) buy-to-open data. It looks for stocks where the previous day's call volume on the ISE is at least twice as great as the put volume. It then sorts the stocks based on the call volume. Since this is buy-to-open data, this can be a good source for finding stocks where optimism is emerging. Of particular interest to me would be situations where we see call activity on stocks that are still in intermediate-term downtrends. This would be a potentially cautionary sign from the contrarian perspective
