Greenlight's David Einhorn said Wednesday at the Sohn Investment Conference in New York he has bought shares of European chemicals company Solvay . "Solvay is an essential chemical company that holds the number one position across all of its markets" Einhorn said. "While all of these are thought of as commodity businesses, they are higher margin and much more stable than most commodity chemical businesses." "All told, Solvay is a commodity chemical company with relatively high and stable margin, a higher return on capital." "At 3.7 times targeted 2028 earnings per share with almost a double-digit dividend yield, it seems too cheap," Einhorn added.
