As of press time, the three major indices opened low and fluctuated, with the Dow down 0.27%, the Nasdaq down 0.31% and the S & P 0.2%.

Although U. S. stocks closed higher on Thursday, the three major stock indexes are still likely to record losses this week. By Thursday's close, the s & p 500 was down 2.6%, the Nasdaq was down more than 3%, and the Dow was down 1.8%.

On Friday, the U. S. government released a closely watched indicator of inflation, the November producer Price Index (PPI). The data showed that PPI rose 7.4% in November from a year earlier, compared with an estimated 7.2%, compared with a previous value of 8.0%. In the United States, PPI rose 0.3% month-on-month in November, compared with an estimated 0.2% and a previous value of 0.2%.

Us 10-year Treasury futures fell sharply to intraday lows after the PPI data, with yields climbing to 3.53 per cent at one point. The spread between 2-year and 10-year Treasury yields widened sharply to about 80 basis points.

In addition, the yield on long-term Treasuries fell about 5.5 basis points, while the yield on short-term Treasuries was slightly higher than Thursday's close.

Last week's ISM report showed that the price index of factory purchases fell to a two-and-a-half-year low in November, but the shift in consumption to services means headline inflation will remain high for some time.

Some price pressures are thought to come from the labour market, and wage growth accelerated in November. This has led economists to expect the Fed to continue to tighten monetary policy and raise policy rates above the recent estimate of 4.6 per cent, which is likely to remain at that level for some time.

Analysts believe that the overall PPI figures are higher than expected and that the downward trend is over, suggesting that in some quarters, the road to falling inflation from its peak may be more bumpy than expected.

"the US stock market is very dependent on inflation data this year and will continue to do so," said Courtney Garcia, a senior financial adviser at Payne Capital Management.

Another important inflation figure will be released in the US next week. The Consumer Price Index (CPI) in November will show whether inflationary pressures in the United States have moderated.

The Fed, which is in the midst of its fastest rate hike cycle since the 1980s, will hold a monetary policy meeting next week. The Fed is widely expected to raise interest rates by 50 basis points next week.
