"...If hydroxychloroquine becomes an accepted treatment, several pharmaceutical companies stand to profit, including shareholders and senior executives with connections to the president. Mr. Trump himself has a small personal financial interest in Sanofi, the French drugmaker that makes Plaquenil, the brand-name version of hydroxychloroquine.
Some associates of Mr. Trump’s have financial interests in the issue. Sanofi’s largest shareholders include Fisher Asset Management, the mutual fund company run by Ken Fisher, a major donor to Republicans, including Mr. Trump. A spokesman for Mr. Fisher declined to comment.
Another investor in both Sanofi and Mylan, another pharmaceutical firm, is Invesco, the fund previously run by Wilbur Ross, the commerce secretary. Mr. Ross said in a statement Monday that he “was not aware that Invesco has any investments in companies producing” the drug, “nor do I have any involvement in the decision to explore this as a treatment.”
As of last year, Mr. Trump reported that his three family trusts each had investments in a Dodge & Cox mutual fund, whose largest holding was in Sanofi."
