The GuruFocus All-in-One Screener can be used to find insider trades from a specific period of time or for a certain range of values. For these stock picks, I went under the Insiders tab and changed the settings for All Insider Buying to "$2,000,000+," the duration to "April 2020" and All Insider Sales to "$2,000,000+."
