The four major banks had a particularly tough day, falling the deepest of the most traded stocks on the OMXS30 list. Handelsbanken lost 2.1 percent, SEB 1.7 percent, while Nordea and Swedbank both fell 1.5 percent.
It was late Friday that an upward trend in Stockholm quickly reversed. The shares among the 30 largest that fell went from being a handful to closing at 17.
The decline occurred after the New York Stock Exchange opened at 3:30 p.m. Swedish time. Soon enough, renewed concerns about overvalued AI stocks had Wall Street trembling on Friday, despite Wednesday's interest rate cut in the US.
At the close in Stockholm, all three major indices in New York were clearly down.
The stock exchanges in Frankfurt and Paris had also turned negative, while the fall in London had intensified.
One dollar costs 9.29 kronor and one euro 10.9 kronor.
With Friday's decline, the Stockholm Stock Exchange has fallen 0.4 percent during the week.
