If the U. S. Government shuts down, it will be the 19th time. Looking at the table below, it doesn’t seem a big deal. The table shows the 18 prior government shutdowns going back to 1976. It lists the start and end date of the shutdown and the gain or loss for the S&P 500 stock index. The average is only a -0.60% loss from beginning to end of the shutdown.
But, here are some considerations:
1. It is too small of a sample size to draw a statistically significant inference. Basic probability needs 30 data points.
2. It only shows the gain/loss from beginning and end of the shutdown.
3. It doesn’t show what happened before and after those dates. Was there more movement/drawdown before or after?
4. It doesn’t show what happened in between the start and end date so it may have been worse.
5. It doesn’t consider market stage at the time of shutdown. Was it overvalued and overbought? Or was it undervalued and oversold?
The truth is; anything can happen.
We don’t know for sure how it will play out. With such a small sample size of prior events and without factoring in the market conditions at the time, what it did in the past doesn’t provide us with a good expectation.
The current condition: if the government shuts down this time:
1. It will be when the U.S. stock market is at the second most expensive fundamental valuation, ever.
2. When investor and advisor bullish sentiment has reached record highs, at this point a contrary indicator.
3. As recent momentum indicators are at the highest levels ever seen before, at this point a contrary indicator.
My solution? always be prepared that anything can happen.
I know how much risk I’m willing to take given the possible outcomes and define my risk by knowing when I’ll hedge or exit.
