Swisscom stock heads into the open after a 1.3 percent gain

At the close on September 21, 2026, Swisscom stock was about 1.3 percent higher on the Swiss market, while the Swiss Market Index also advanced more than 1 percent. Index reshuffling within the SMI added context to the move.

Swisscom stock closed higher on the Swiss market on September 21, 2026, with the shares up about 1.3 percent versus the previous session in Swiss francs on the SIX Swiss Exchange. The move came as the Swiss Market Index also gained about 1.23 percent and approached the 14,000-point mark at the close on September 21, 2026.

September 21, 2026 in numbers

Swisscom AG (ISIN CH0008742519) participated in a broadly positive Swiss equity session on September 21, 2026, when its shares added around 1.3 percent on the Swiss market in Swiss francs, according to intraday data from Swiss trading venues. In the same session, the Swiss Market Index closed at 13,956.58 points, up 1.23 percent on the day, with the closing level sitting between the intraday low and high of 13,929.15 and 13,983.56 points as reported by Finanzen.ch. Within that index, Swisscom was cited among the gainers with an advance of about 1.3 percent, alongside other constituents that rose between roughly 1.3 percent and 2 percent in the session, per the same market wrap from Finanzen.ch. Another report on Swiss large caps noted that Swisscom shares improved by about 1.3 percent as part of a trading day shaped by sector rotation in the Swiss Market Index, where health care names increased their weight and Swisscom was one of the stocks leaving the benchmark, according to Finanzen.ch. That index reshuffling, combined with declining oil prices that supported Swiss equities more broadly, framed the day’s trading pattern even though Swisscom still closed higher in that last completed session.

Today’s drivers and events

Today, September 22, 2026, Swisscom heads into the open without a scheduled earnings release or annual meeting explicitly tied to this date in public investor calendars over the next few trading days, but the recent change in the Swiss Market Index composition continues to shape how Swisscom is positioned in the Swiss equity landscape, as noted in the same index adjustment report from Finanzen.ch. Broader market sentiment today will likely continue to be influenced by the factors that lifted the Swiss Market Index on September 21, 2026, including lower oil prices and a constructive tone in global equities described in a recent international markets wrap by SWI swissinfo.ch, which highlighted how declining energy prices helped equity benchmarks such as the S&P 500 advance by 1.5 percent on the same day. Against that backdrop, Swisscom enters today’s Swiss session with its most recent close above the prior day’s level and with the Swiss Market Index near 14,000 points after Monday’s gains.
