Despite the freefall that US and UK stock markets took this morning [Friday] due to the impact of last week's events, trading by the afternoon had rallied slightly.
By Friday morning, the FTSE-100, US Nasdaq and US Dow Jones Industrial Average market indices had plummeted to between a sixth and seventh, compared to pre-attack levels.
Since closing on 11 September, the market has reacted thus:
Nasdaq: 1695.38 to 1409.02 - down 16.9 per cent
DJIA: 9605.51 to 8109.99 - down 15.6 per cent
FTSE-100: 5034.70 to 4336.70 - down 13.9 per cent
The markets have dropped despite share buyback schemes, interest rate cuts from the US federal authorities, and warnings from stock market regulators that short-selling speculation will be clamped down on.
The FTSE-100 share index early Friday plunged to its lowest levels since April 1997, before steadying to just over five points lower at 4336.70 by 1500hrs BST. Insurance, banks, airlines, oil and tech stocks were all hit hard.
Analysts said the market was best beset by a climate of fear, and while what was happening should not be described as a crash, there were precious few buyers in the market.
At mid-day in the UK, not one stock in the FTSE-100 was up on the day.
Revised figures posted by insurers suggested the attacks would result in $18bn in liabilities, but analysts expect these figures to increase to $30bn once final calculations are resolved.
However, some commentators believe that despite the situation, investors will soon look at the market as reaching a level where bargains are to be had.
