The Dow Jones gained 0.13%, the Nasdaq index gained 0.16% and the S&P 500 index gained 0.12%.
On Thursday, the S&P 500 had managed to close up 20% from its low of October 12.
On Friday, the most representative index of the New York Stock Exchange failed, however, to finish above 4,300 points, a new important technical threshold.
"This week there have been very few economic indicators and the market has had to think for itself, for once, which has been positive," said Quincy Krosby of LPL Financial.
For Maris Ogg, of Tower Bridge Advisors, it emerged that "the worst is behind us", according to the analyst, that is to say almost all of the monetary tightening and the banking crisis, even if investors still expect a deterioration in the economy.

Another significant fact of the week, the movement was not dictated by a handful of giant technology capitalizations as since the beginning of the year.
In June, the S&P 500 index at equal valuations, which gives equal weight to each company, gained 4%, compared to a decline of 1.4% since the beginning of the year.
"It's really encouraging to see momentum that encompasses a larger share of the market, because one of the things I've been really worried about so far is how focused the upward movement is," Low said.
Another evidence was that equities withstood a sharp rise in bond yields, which followed the surprise tightening of the Canadian central bank (BoC) on Wednesday.
The price of bonds fell when that of equities rose, a correlation that has historically been strong but had tended to fall apart in recent years.
The yield on 2-year US government bonds, more volatile than its 10-year equivalent, stood at 4.60%, against 4.51% the previous day at the close.
