WIG20 Index — Level, Chart & Constituents

What the WIG20 measures

WIG20 is a stock market index that tracks the performance of the largest companies listed on the Polish stock market. It is quoted in PLN and belongs to the European family of indices, alongside peers such as the Euro Stoxx 50, the STOXX Europe 600 and the ATX (Austrian Traded Index). Rather than measuring the whole market, WIG20 focuses on a core group of major listed companies, so its movements are widely read as a snapshot of how the most significant part of the Polish equity market is doing on a given day.

Key numbers explained

For a beginner, an index level is simply a reference number: it has no currency units of its own beyond the quotation currency, and what matters is how it changes over time. Here are the most informative figures for WIG20 right now:

• Current level: 4,180.26 points — the index's latest quoted value, expressed in PLN.
• Today's change: -0.3% — the index is slightly lower than at the previous close, a modest daily move.
• Today's range: 4,169.69 – 4,202.68 — the lowest and highest points reached during the session, showing how much the index has moved within the day.
• 52-week range: 4,169.69 – 4,202.68 — the lowest and highest levels of the past year; today's range currently matches this span, meaning the index is trading near the extremes of its recent annual range.

Reading these together: the level tells you where the index stands, the percentage change tells you the direction of the day, and the ranges tell you the volatility — how wide the swings have been, both today and over the past year.

What to watch

Like any broad equity index, WIG20 can be influenced by general factors rather than anything specific to one company. These typically include:

• The earnings and overall health of the large companies that make up the index.
• Macroeconomic conditions such as interest rates, inflation and currency movements, which affect equities across Europe — a dynamic also visible in regional peers like the OMX Stockholm 30 or the PSI (PSI 20).
• Investor sentiment towards European markets in general, often tracked through broad benchmarks such as the STOXX Europe 600.
• Changes in the composition of the index itself, when constituent companies are added or removed.
