Chart of the Day – 10.18.2008***


CHART OF THE DAY….A couple of weeks ago I quit watching the stock market’s gyrations during the day because it was obvious that they didn’t really mean anything. Up, down, whatever: the events of the final hour, from 3 pm to 4 pm were all that mattered, wiping out huge gains in an instant or turning small losses into disasters.

Now comes a nice chart via Zubin Jelveh that demonstrates the point graphically. As you can see, normally the stock market moves anywhere from a quarter of a percent to one percent in the final hour of the day. That’s roughly the same as the other six hours the market is open. But since mid-September? Final-hour volatility jumped to 2%, and then earlier this month to a high of 6%. That’s as much movement as the entire rest of the day. So if you’re the nervous sort, give yourself a break and take your eyes off the hourly movements of the Dow. Just check in at 4 pm and be done with it.

Need some more charts? Ezra Klein has a nice one showing that sometimes placebos work just as well as surgery. (With a followup here.) Maybe those Christian Scientists are on to something after all?

MORE HARD-HITTING JOURNALISM

In 2014, before Donald Trump announced his run for president, we knew we had to do something different to address the fundamental challenge facing journalism: how hard-hitting reporting that can hold the powerful accountable can survive as the bottom falls out of the news business.

Being a nonprofit, we started planning The Moment for Mother Jones, a special campaign to raise $25 million for key investments to make Mother Jones the strongest watchdog it can be. Five years later, readers have stepped up and contributed an astonishing $23 million in gifts and future pledges. This is an incredible statement from the Mother Jones community in the face of huge threats—both economic and political—against the free press.

Read more about The Moment and see what we've been able to accomplish thanks to readers' incredible generosity so far, and please join them today. Your gift will be matched dollar for dollar, up to $500,000 total, during this critical moment for journalism.
