The Main Market has three tiers by market cap. Large Cap is over 1 billion euro with over 100 companies including Volvo, Ericsson, Atlas Copco, H and M, and Investor AB. Mid Cap is 150 million to 1 billion euro. Small Cap is under 150 million.

First North is the growth market with lighter listing rules and higher risk. Nordic SME is the smallest segment for micro caps. Most retail traders should stay on the Main Market.

Key indices

OMXS30 is the blue chip benchmark of the 30 most traded names. OMXSPI covers all Main Market stocks. Sector indices split it into industrials, financials, healthcare, and more. OMXS30 ESG screens constituents for sustainability criteria.

Major companies

Atlas Copco is about 11 percent of OMXS30. Investor AB about 9 percent. Volvo about 8 percent. Ericsson 6 percent. H and M, Handelsbanken, Swedbank, SEB, Sandvik, and Essity round out the top ten.

Trading

Swedish stocks trade in SEK. International brokers convert at their rate. Interactive Brokers offers near spot rates. SEK has been structurally weak versus USD and EUR, which gives dollar investors a tailwind in uptrends and a headwind in downtrends.

How to start

Open an Interactive Brokers or Saxo account. Convert to SEK. Begin with OMXS30 large caps for the best fills. Use limit orders. Watch Riksbank decisions because SEK moves sharply on rate surprises. Check the index trend before trading individual names.
