During the previous eight trading days of decline - created by concerns about the consequences of the Iran war - more than 5 percent of the Stockholm Stock Exchange's value has been erased.
Since the turn of the year, the OMXS index has been up 1.8 percent.
The oil price has fallen sharply to around $116.50 per barrel for North Sea oil. During the night, a new peak during the Iran war of over $126 per barrel was noted. The dollar and market interest rates are also being pressured downwards.
It is unclear what is causing the reversal. In morning trading, the market was concerned that the Trump administration would resume bombing in Iran after several weeks of a ceasefire.
