Shares of Investor AB have emerged as the most heavily net-sold stock among retail investors on the Avanza platform, according to data reported by Dagens Industri.

The selling pressure comes after a significant rally in the stock, driven by the elimination of the substance discount in the company's valuation.

This shift has prompted private savers to lock in gains, highlighting a cautious stance among individual investors despite the broader bullish sentiment on the Stockholm Stock Exchange.

The move underscores a divergence between institutional valuation metrics and retail trading behavior.

While the removal of the substance discount has theoretically improved the stock's appeal to long-term holders, the immediate reaction from Avanza users suggests a preference for realizing profits after the recent price appreciation.

This pattern of profit-taking is often observed in stocks that have experienced sharp run-ups, as retail traders reassess risk-reward ratios at higher price levels.
