President Donald Trump has asked the US Securities and Exchange Commission to investigate moving public companies to a six-month rather than three-month reporting cycle to combat an excessive corporate focus on the short term.

Progressive critics and chief executives alike decry what they see as a myopic market’s pressure to cut back on investment and increase dividends and share repurchases. In her 2016 presidential campaign, Hillary Clinton proposed raising capital gains taxes for investments held for less than six years to combat short-termism.

Few ideas command such widespread support as the notion that companies should be induced to concentrate more on the long term. Unfortunately, while there are important ways in which corporate governance can be improved, the idea that a myopic market forces companies to forgo highly attractive investment opportunities is unsupported either by logic or evidence.
