WIG20 breaks 19-year record, closing at 3,943 points as Polish bull market extends its run

The Warsaw Stock Exchange's WIG20 index broke through its October 2007 intraday record on Monday, 3 August 2026, reaching 3,963.21 points before closing at 3,943. The milestone ends a 19-year wait and confirms the strength of a bull market that began in autumn 2022. The broader WIG index, which has been setting records for nearly three years, closed up 0.7% at 148,428.28 points. Total capitalisation of the 403 companies on the main market now exceeds 2.9 trillion złoty.

What drove the rally

Banks have been the engine of the upswing. The WIG-banki index is up 33% year-to-date and 196% over three years, powered by high interest rates and record net profits. PKO BP and Bank Pekao have doubled or tripled in value, while Alior Bank and mBank surged 200–300% from their October 2022 lows. State-controlled companies also played a decisive role: Orlen alone contributed 7.7 percentage points to WIG20's gain this year, accounting for roughly a third of the index's 23.1% advance. LPP, the clothing giant, rebounded strongly after its exit from Russia, and Budimex rode a wave of infrastructure orders.

A price index with a dividend handicap

WIG20 is a price index, meaning it does not adjust for dividends. Every time a heavyweight stock goes ex-dividend, the index mechanically drops. PKO BP and Orlen, with weights of 15.1% and 14.2%, have an outsized effect. Monday was the last day to buy PKO BP shares with the right to a 6.14 zł dividend; the ex-dividend adjustment on Tuesday was expected to shave about 0.8 percentage points off the index. Orlen's 8 zł dividend cut on 17 June had already knocked a similar amount off WIG20. The record was therefore achieved, as one report put it, at the last moment.

What the GPW chief said

WIG20 is a price index, so investors who reinvested dividends since the 2007 record achieved a return of over 120 percent, or about 4.3 percent annually. They managed to beat inflation, which totalled around 84 percent over that period.

Bardziłowski stressed that the new high shows the capital market is strengthening its role in the economy and that global investors see potential in Poland's largest companies. He noted that the index composition now reflects two decades of economic change, with modern consumer, retail and e-commerce firms gaining weight alongside traditional banking and energy. Still, he pointed out that domestic companies' capitalisation is only about 30% of Poland's GDP, compared with an EU average of 70% and over 100% in the most developed countries.

Analysts see slower gains ahead

Despite the euphoria, market professionals are tempering expectations. BM BNP Paribas experts noted that while Polish equities remain cheaper than US and most European markets (a forward price-to-earnings ratio of about 14.35), the valuation is already high relative to Poland's own history. They expect the uptrend to continue but at a slower pace and with greater volatility.

Looking at the whole set of valuation metrics, I would say Polish stocks have already come a long way from the bargain levels of a few years ago. Some measures are clearly above historical averages — for example, the price-to-book ratio for WIG reached about 2.0 in July, the highest since 2008.

Hońdo added that if price-to-book or price-to-sales were to reach the extremes of mid-2007, they would still need to rise by roughly 50% and 40% respectively, suggesting the market is not yet in bubble territory.

Sebastian Buczek, president of Quercus TFI, flagged the tense situation in the Middle East and the approach of September, historically the weakest month for equities. His firm has shifted its stance on stocks to "neutral minus." Przemysław Smoliński of BM PKO BP saw no technical signals of an impending trend reversal for blue chips or mid-caps, though the small-cap sWIG80 remains in a corrective phase.

Global backdrop and what comes next

The Polish rally has been supported by favourable global conditions. A weakening dollar, partly attributed to Trump administration policies, redirected capital from the US to emerging markets, with Poland among the main beneficiaries. The WIG's total return of about 225% since October 2022 outpaces developed markets, though Hungary's BUX has risen nearly 280% over the same period. On Monday, reports of de-escalation in the Middle East added to the positive mood.

Looking ahead, the market faces potential headwinds from expected interest rate hikes by the Federal Reserve, the European Central Bank and the Bank of England in September. After a July in which WIG20 gained 9.28% and WIG added 8.67%, a period of consolidation in August is seen as the most likely scenario, with a sharp sell-off considered improbable.
