Wall Street strategists are suddenly very busy as narrowing poll numbers in the last week have taken the consensus election opinion from a Hillary Clinton blowout to a small chance of a Donald Trump upset.
Clients want to know how to hedge against a win by the unpredictable New York businessman.
Morgan Stanley is the latest to give trades that will protect clients' portfolios from a Trump win and even allow them to profit.
"Polls may tighten more and outcome uncertainty rise, but our base case is a divided government limiting policy action to incremental tax changes and infrastructure spending," strategist Michael Zezas wrote in a note to clients Tuesday.
"However, a tighter race risks markets starting to reflect the early policy path of a Trump presidency (an 'accidental stimulus' and more trade protections). It also de-emphasizes the risks of a Democratic sweep."
Zezas cited how the final polling averages in the 1980, 2000 and 2012 elections were off by 3 percentage points or more versus the actual voting results. The current FiveThirtyEight national polls popular vote gap between the candidates is 3.7 percentage points.
