There has been a big change of opinion for investors over the last two weeks or so. For almost all of this year, a Biden victory, and especially a blue sweep were seen as potential negatives for the economy vis-à-vis a Trump reelection. Any gains in the polls for Democrats was seen as a negative for the economic outlook, particularly because of the chance for higher taxes. However, the rising odds for a blue sweep have managed to assuage an even bigger fear for investors—a contested election that could drag on for months. Accordingly, gains in the polls for Democrats have seen rising markets. Goldman Sachs feels strongly enough to say this: “All else equal, a blue wave would likely prompt us to upgrade our [US economic growth] forecasts”.
FINSUM: We think there are two specific reasons perceptions have changed. Firstly, the decreased chances for a contested election (very arguable if that is actually true); and secondly, the odds for bigger stimulus and infrastructure packages, which would be positive for the economy.
