Swiss packaging producer SIG’s management bought CHF 1.3 million of its own shares on Tuesday, capitalizing on a 28% intraday plunge that followed the abrupt departure of CEO Mikko Keto and the appointment of interim leader Ann-Kristin Erkens.
The stock slumped 17% at Monday’s open and fell as much as 28% before paring losses, erasing roughly CHF 200 million in market capitalization. The decline marked the second major leadership-driven selloff in 12 months, compounding a 70% drop from SIG’s 2021 record high.
According to SIX Exchange Regulation data, three buy transactions were recorded on August 18. Two purchases totaling CHF 274,000 were executed by executives, while a CHF 1 million purchase was made by a board member. The transactions reflect a classic buy-the-dip strategy, with management signaling confidence that the market overreacted to the leadership change.
SIG’s board had previously endorsed Keto’s restructuring plan last autumn, describing him as the right leader to implement a strategic review amid persistent underperformance. His sudden exit and the appointment of Erkens, a former finance executive, suggest internal disagreement over the pace or direction of change.
The company’s long-term outlook now depends on Erkens’ ability to stabilize operations and deliver on restructuring targets. Historical precedents offer mixed signals: while some executives have successfully rebuilt value after similar moves, others have required extended patience to turn performance around.
The timing of the purchases aligns with a broader pattern among Swiss industrial firms, where insider buying often coincides with valuation troughs. However, the effectiveness of such strategies remains contingent on execution and external market conditions.
