Stocks Can Still Go Up When the Government Shuts Down

The US government shut down after Congress was unable to reach a funding agreement. This is the 11th shutdown since 1981.1 During these shutdowns, many nonessential functions of the government cease. In most cases, the fiscal shortfall was resolved within a few days. However, four shutdowns lasted at least five days.

How did stocks fare during these prolonged episodes? The US market ended higher at the conclusion of three and was flat in the other.

So, while a shutdown may be a nuisance,2 history suggests it’s probably not cause for concern in your portfolio.
