The Dow Jones Industrial hit the 20,000-point threshold on Wednesday. What led the US stock market index to its highest ever level? The 20k benchmark itself is just a number, of course, but is symbolic of strong share performance in recent months, particularly compared to its mixed experiences over the Jan. ’15 – Dec. ’16 period shown in today’s chart. The ‘Trump rally’, resulting from investor confidence that the new administration will deliver pro-growth fiscal policies, has led the Dow on a path of far steeper growth than it would likely have enjoyed under Clinton. An expected victory from Trump’s former rival had been pulling US shares down in line with the Democrat candidate’s intention to continue various Obama-led interventions – such as tough environmental restrictions from the former administration, which the new POTUS is rolling back with executive orders to resume the Keystone and Dakota Access oil pipeline projects.
