On Tuesday, the FAS data revealed that the F100 index was down a tenth of a percent to 4,743 points.
On Friday, the index hit a new low of 4,074 points.
It’s a very low level for the F1 stock market, which is the benchmark index for a wide range of companies.
At its peak on Monday, the value per share for the index was more than $1,700.
“It’s going to be very hard to sell a stock that’s at this low level,” said Robert Hagg, a senior fellow at the Peterson Institute for International Economics.
The FTSe 100 index closed the week at 5,734, down 2.5 percent.
The FTSI-100, the most closely watched index in the world, has been down 1.4 percent since Friday.
Fears over a potential stock market collapse caused by a political crisis and a slowdown in China could also hurt the FSI index.
The Chinese index has risen nearly 7 percent this year.
In a sign of how the stock market is recovering, the S&P 500 index ended up 2.7 percent higher on Tuesday, while the Dow Jones Industrial Average rose 4.2 percent.
On Thursday, the Nasdaq composite index climbed 1.6 percent to close at 7,983.
