Historical performance

WIG20 is a price index — it doesn't include dividends. For many years its nominal performance looked poor compared to the S&P 500. However, the WIG20TR index (total return, with dividends) gives a more complete picture.

Polish dividend companies (banks, energy) pay relatively high dividends (4–8%), which improves real returns.

• Beta ETF WIG20 — ETF listed on WSE, tracking the WIG20 index
• WIG20 futures (FW20) — for advanced investors, with leverage
• Investment funds — many TFIs offer Polish equity funds

FAQ

What is WIG20 and how is it constructed?

WIG20 is the flagship index of the Warsaw Stock Exchange, tracking the 20 largest and most liquid companies by free-float market capitalisation. It is reviewed quarterly, with a 15% cap on any single issuer and a 30% cap on any single sector to limit concentration.

Does WIG20 include dividends?

No — the headline WIG20 is a price index and does not reinvest dividends. For a total-return view that includes dividends, look at the WIG20TR variant, which historically shows materially higher returns given that Polish blue chips pay relatively high dividend yields.

How can I invest in WIG20 from a regular brokerage account?

Common routes are ETFs that track the index, mutual funds with WIG20 as benchmark, or futures contracts on WIG20 for advanced investors. ETFs are usually the simplest entry point and can sometimes be held inside IKE or IKZE tax-advantaged accounts, depending on broker availability.

Why has WIG20 underperformed global indices over the long run?

The index is heavily weighted toward banks, energy, and state-influenced companies, which face regulatory and political risk premia. Its narrow composition of 20 names also makes it more cyclical and less diversified than broad benchmarks like the S&P 500 or MSCI World.

How does WIG20 differ from mWIG40 and sWIG80?

WIG20 covers the 20 largest companies, mWIG40 the next 40 mid-caps, and sWIG80 the following 80 small caps, with separate methodologies and free-float adjustments. Combining them gives broader exposure to the Polish market beyond the most concentrated blue-chip names.
