“This is a test. This is only a test. If this had been an actual emergency, you would have been instructed to tune to one of the broadcast stations in your area.”
When I was kid, the Emergency Broadcasting System would issue these test warnings on radio and TV to make certain that in the event of a serious national crisis, people would know where to tune for important information.
In that spirit, it just might be time to test the early warning system for the economy and the stock market.
