The president’s media company has tried its hand at a half-dozen new lines of business to lift its stock, but nothing has worked. But shares of the parent company, Trump Media & Technology, kept falling so it decided to become more than a media company, and branched into unrelated industries like online betting, finance, investment funds, buying and storing bitcoin and nuclear energy. Several current members, including Massachusetts Sen. Elizabeth Warren, say they will hold formal investigations of Trump’s businesses, including Trump Media, should they take over. Despite the help, investors still aren’t convinced Trump Media has a rosy future. On Monday, Trump Media dove again, down 8% to $9.39 a share.
