Company Stock Price Reactions to the 2016 Election Shock: Trump, Taxes and Trade


  • Wagner, Alexander F
  • Zeckhauser, Richard
  • Ziegler, Alexandre


Donald Trump�s surprise election shifted expectations: corporate taxes would be lower and trade policies more restrictive. Relative stock prices responded appropriately. High-tax firms and those with large deferred tax liabilities (DTLs) gained; those with significant deferred tax assets from net operating loss carryforwards (NOL DTAs) lost. Domestically-focused companies fared better than internationally-oriented firms. A price contribution analysis shows that easily-assessed consequences (DTLs, NOL DTAs, cash tax rates) were priced faster than more complex issues (net DTLs, GAAP tax rates, foreign exposure). High-tax firms outperformed (underperformed) on days when the media attended more (less) to corporate taxes.
