Friday marked the 20th anniversary of Black Monday.
On that day, the Dow Jones Industrial Average fell by 508 points. Doesn't sound like that much today, but in fact that was a 22.6% fall, equivalent to more than 3,000 points today.
So by those standards, Friday's 367 point fall wasn't anything to write home about.

But it's certainly re-awakened worries of what may lie ahead
On Friday, the S&P 500 fell 2.6% to 1,500. That was its worst one-day fall since "the credit squeeze hit in mid-August," reports the FT.
So why the sudden panic, just as everything seemed to be right with the world once again?
A few things are troubling investors. For one, third quarter earnings results. Conglomerate Caterpillar saw its shares drop by more than 8% as the group warned that full-year results would miss Wall Street hopes. It said that several of the industries it supplies are in recession, with the weak housing market in particular hurting sales of machinery.
Meanwhile, sales at both 3M and Honeywell also fell short of Wall Street's expectations in the third quarter. All of this hammered already fragile investor confidence.
The trouble is, the new story gripping the markets is the idea that, effectively, the US doesn't matter anymore. Asia and the rest of the world can happily keep growing and keep companies' coffers expanding without the US consumer to prop them up so why not buy shares in those companies most exposed to the global growth story and let America go into hibernation for a while?
It's a nice story. But as Bill Strazzullo of Bell Curve Trading put it: "A company like Caterpillar should be a poster child for global growth and the benefits of the weak dollar." So if it can't make hay while the sun is apparently shining, then who can?
"It makes you question: is global growth really that strong? Has the earnings kick from the weak dollar played itself out?"
John Authers, also in the FT, points out something else to worry about. It's not just Caterpillar that's disappointed so far "the 22% of S&P 500 companies to have reported have on average, reported a decline in earnings of 14.8%" for the third quarter, he says.
Now, this is partly because many of the results so far have been from financial companies, which of course have suffered severely in the credit crunch. But even so, overall analysts now reckon third quarter earnings in the US will shrink, for the first time since 2002, by 3.7%. That's against initial expectations for 7.1% growth.
The reason that shares have held up so well so far is that markets are expecting a rebound this quarter (the fourth) and during the first three months of 2008. But as Authers points out, "profit margins, like economies, tend to revert to a long-term mean."
In other words, the higher they are, the more likely they are to fall. And Rob Arnott of Research Affiliates tells Authers that "earnings are currently 60% above their 10-year average." According to Arnott, "the average 10-year growth in earnings after they get 50% or more above their 10-year average is zero."
So Arnott is basically saying that over the next 10 years we should expect earnings growth from S&P 500 companies to average zero. That's not good news for stocks which are, after all, priced according to future earnings expectations, give or take the odd mania or two.
That means "there is every reason to fear that earnings growth will fall sharply next year, even if the US and the developed world can avoid a recession."
And that last is a big if, with the US housing market showing no sign of improving.
Even though he's bullish on stocks in the longer-term (see Avoid property - but I think shares are good value), economist and stockbroker James Ferguson thinks we may well see another large correction (we're talking about near 20%) in the near future as markets start to realise that the US economy isn't going to get any better.
