Corporate calendar for today

The SIX consolidated corporate calendar lists various upcoming issuer events that can influence Swiss stocks, including Sulzer, around this period, though specific Sulzer dates fall beyond the immediate one week window visible in the latest update from SIX Group. With no new Sulzer specific release reported early on September 17, 2026 in the available feeds, the stock heads into today’s open primarily with the momentum from its recent gain, the still large gap to some valuation models, and the broader backdrop of stable Swiss blue chip trading in the last session.
