The Stockholm Stock Exchange closed in negative territory on Tuesday, as afternoon selling erased earlier gains and left the benchmark index down for the session.
The downturn was driven by sharp declines in high-profile technology and security names, which dragged on broader sentiment.
Despite the negative close, there were notable outperformers.
Casino operator Evolution emerged as one of the day's top gainers, rising double digits.
Another company, which released a report during the session, also posted significant gains, providing a counterweight to the broader market weakness.
The session's volatility reflects a shift in investor positioning.
