OMX Stockholm 30 Index — Level, Chart & Constituents

What the OMX Stockholm 30 measures

The OMX Stockholm 30 (symbol OMXS30) is a stock market index that tracks the 30 most traded and largest companies listed on Nasdaq Stockholm. As a benchmark for the Swedish equity market, it is part of the broader European landscape alongside peers such as the BEL 20, the OBX Index (Oslo), the OMX Copenhagen 25, the FTSE/ATHEX Large Cap, the ATX (Austrian Traded Index), the WIG20, and the BIST 100. The index is denominated in Swedish krona (SEK) and reflects the aggregate price movement of its constituents, making it a common reference for Swedish large-cap performance.

Key numbers explained

• The current index level is 3,295.03 points, which is the weighted aggregate price of the 30 constituents expressed in SEK.
• Today's trading range was 3,287.53 – 3,321.02, showing the lowest and highest level reached during the session.
• The price change today is +0.73%, indicating the session's net movement relative to the previous close.
• The 52-week low is 2,640.82 and the 52-week high is 3,349.5, framing the range the index has traded within over the past year.
• The index is market-capitalisation weighted, meaning larger companies have a proportionally greater impact on the level.
• The level of an index is a number that reflects the aggregate price of its constituents; it is not a currency value and should not be compared directly across indices without considering their composition and base.

What to watch

The OMX Stockholm 30 is sensitive to movements in Swedish corporate earnings, interest rate decisions by the Riksbank, and broader European economic data. Currency fluctuations, particularly the SEK against major currencies, can also influence the index's performance when viewed from outside Sweden. Sector shifts, such as changes in exposure to industrials, technology, or financials, affect the index's direction as constituent weights evolve.
