I have written 2 dutch books on value investing: "Aandelen selecteren als waardebelegger" and "Beleggen in bull- en bearmarkten". See bol.com (search for the titles). As a mathematician (Ph.D.) I am most interested in investment strategies with statistically favorable returns. In particular I invest in net-nets (20-30% average annual returns). I find companies with low Enterprise Value/Earnings before Tax and Interest (EV/EBIT) and strong balance sheets (20% average annual returns) also very interesting. Since such stocks are rare I invest globally. Send me a message with your email address to get example articles of my premium research on Seeking Alpha.
