Greek stocks vs. Nasdaq 100: Which market won in the last 5 years?

On the morning of 29 June 2015, Greeks woke up to find their banks closed.

ATMs were limited to €60 a day. The Athens Stock Exchange did not open for trading.

Capital controls, the kind associated with crisis-era emerging markets rather than members of a developed-economy currency union, had arrived.

Five years earlier, in April and June 2010, Standard & Poor’s and Moody’s had cut Greek sovereign debt to junk, the first eurozone member to lose investment grade.

By February 2016 the Athex Composite had bottomed at 516.7 points, a fall of more than 90% from its October 2007 high of 5,334.5. The FTSE Athex Banks index, the country’s lenders, had collapsed by 99.6%.

Greek equities had ceased to function as an asset class.

They had become an obituary.

A decade on, the obituary needs rewriting. The Athens Composite Index has returned roughly 146% over the past five years on a total-return basis.

The Nasdaq 100, riding the artificial intelligence supercycle that has dominated global equity narratives, returned 116% over the same window. The S&P 500 delivered only about half of Greece’s gains, while European large-cap equities – tracked by the Euro STOXX 50 – achieved barely one-third.

This is the story of how Europe’s cautionary tale became one of the best turnaround trades of the modern era.

Greek stocks beat Nasdaq 100 over 5 years: Here is why

To understand the rally, start with the lenders. National Bank of Greece, Eurobank, Piraeus Bank and Alpha Bank carried the heaviest load through the crisis decade.

By late 2016 their combined non-performing loan ratio peaked near 47%, the worst in the European Union. For perspective, most other troubled European banking systems peaked at between 5% and 8%.

Greek lenders were not facing a credit problem. They were carrying a depression on their balance sheets.

The clean-up unfolded in two stages.

The Hellenic Asset Protection Scheme, known as Hercules, allowed the banks to securitise and offload roughly €57bn of bad loans through state-backed guarantees on the senior tranches.

The second leg was the slower work of organic profitability: stabilising deposits, restructuring cost bases, restoring net interest margins.

From bailout to bull market: The Athens turnaround

Combined net profits of the four largest Greek banks reached close to €5bn in 2025.

Shareholder payouts followed suit. Piraeus, Eurobank and Alpha Bank distributed around 55% of earnings, while National Bank of Greece pushed its total payout ratio to 86%, supported by aggressive buybacks.

Konstantinos Hatzidakis, then Greece’s minister of economy and finance, captured the moment in the IMF’s Finance & Development journal in June 2025.

“We have cleaned up bank balance sheets and curbed nonperforming loans. This major milestone has enabled lenders to regain their essential role in financing the real economy,” he wrote.

Hatzidakis pointed to rising deposits, stronger capital buffers and what he described as “a tangible vote of confidence” in the system: the successful sale of the Hellenic Financial Stability Fund’s bank stakes to long-term foreign investors.

“The Greek economy,” he added, “has consistently outperformed expectations, often by a significant margin.”

The quiet engine behind Greece’s economic miracle

The fiscal side of the recovery has received far less attention, but it has been equally important.

In a paper published by the IMF last week, economists Andrew Okello, Stoyan Markov and Chenghong Wang described the transformation of Greece’s tax administration as “one of the quiet engines behind Greece’s broader economic recovery”.

They divided the reform process into three overlapping stages.

The first, between 2010 and 2012, focused on stabilising government revenues under Troika supervision. One of the earliest breakthroughs came via VAT digitalisation: only 65% of registered taxpayers filed VAT returns on time in 2010, compared with 96% by 2014.

The second stage, between 2013 and 2017, centred on institution-building. Greece consolidated 288 local tax offices into 119 and established the Independent Authority for Public Revenue under a landmark 2016 law.

By 2017, the authority had become operational with its own budget and independently selected management board. During that period, the tax-to-GDP ratio rose from 25.8% to 27.6%.

The third stage, from 2018 onwards, introduced real-time electronic invoicing, point-of-sale connectivity and digital analytics systems. VAT revenues climbed from 7.1% of GDP in 2010 to around 9.5% in 2025.

Overall, Greece’s tax-to-GDP ratio rose from 20.5% in 2009 to roughly 28% in 2025.

The result has been a dramatic fiscal turnaround.

Greece recorded a primary surplus close to 5% of GDP in both 2024 and 2025, making it one of only a handful of EU countries running a fiscal surplus at all.

Meanwhile, sovereign spreads over German bunds — which once exceeded 30 percentage points during the peak of the crisis — have returned to levels last seen before the 2008 financial crisis.

According to the IMF’s March 2026 Article IV statement, Greece’s public debt-to-GDP ratio fell by around 10 percentage points in 2025 alone, reaching roughly 145%, down from a peak near 210% in 2020.

The IMF estimates the cumulative decline at roughly 65 percentage points from the pandemic-era peak.

Credit-rating agencies eventually followed. Scope Ratings restored Greece to investment grade in August 2023, followed by DBRS later that year, S&P in October 2023 and Fitch in December 2023.

Moody’s — the final holdout among the major agencies — upgraded Greece to Baa3 in March 2025 and reaffirmed the rating in April 2026.

For the first time in more than a decade, every major ratings agency now classifies Greek sovereign debt as investment grade.

Cheap when nobody wanted to look

The third pillar of the rally was valuation.

Greek equities entered the recovery period trading at discounts that became increasingly difficult to justify once balance sheets stabilised.

Even after the surge, Eurobank Equities estimates Greek banks are trading at roughly 9 times expected 2026 earnings and 1.4 times tangible book value — still more than 20% below European peers.

UBS estimates the sector’s average 2027 price-to-earnings ratio – a key measure of how cheaply or expensively stocks trade relative to expected profits – at 8.4x, compared with 9.5x for European banks overall. For comparison, US equities currently trade at more than 20 times forward 12-month earnings.

Over the past five years, shares of National Bank of Greece and Piraeus Bank have each surged by roughly 500%. Yet despite the extraordinary rally, both lenders still trade at single-digit earnings multiples.

The most structural financial change arrived last.

On 24 November 2025, Euronext completed its acquisition of the Athens Stock Exchange after roughly 74% shareholder acceptance of the all-share offer.

Greek stocks now sits inside Europe’s largest equity listing venue, alongside more than 1,800 listed companies.

The mechanical consequence is a broader pool of natural buyers. International index funds tracking pan-European benchmarks now hold Greek names automatically.

MSCI – the world’s largest index provider – is reviewing Greece for a potential upgrade to Developed Market status, effective September 2026 if approved, which would shift the country out of the small bucket of emerging-market money still chasing it and into the much larger pool of developed-market index allocations.

JP Morgan has forecast a 16% return for the MSCI Greece index in 2026.

Inside the sector, the maturing is showing up in mergers and acquisitions. In May 2026 Eurobank agreed to acquire 80% of Eurolife FFH Life Insurance for around €813m, a deal expected to lift group fee income by roughly 12%.

National Bank of Greece signed a Memorandum of Understanding with Allianz on a 30% stake in Allianz Hellas, with the partnership projected to add 4% to earnings per share.

The Optima offer for Euroxx underscores the same dynamic.

Greek financials are no longer just rebuilding. They are consolidating.

A decade later, Greece looks different

None of this means Greece is insulated from external shocks.

The IMF warned in March 2026 that the outlook remains “clouded by the conflict in the Middle East”. Tourism still accounts for roughly 21% of Greek GDP, leaving the economy vulnerable to geopolitical disruptions.

The Recovery and Resilience Facility — which has underpinned much of the country’s recent investment boom — is also due to wind down in August 2026.

Inflation remains elevated, running at 3.1% year-on-year in February 2026.

Hatzidakis himself acknowledged the remaining weaknesses in his June 2025 essay: investment still trails the EU average, productivity remains below European peers, and female labour-force participation is still among the lowest in the bloc.

Piraeus chief executive Christos Megalou told analysts during the bank’s first-quarter earnings call that a prolonged period of elevated energy prices could slow Greek GDP growth to between 1.5% and 1.6%, albeit still above the EU average.

Still, Greece stands as one of the clearest examples in modern financial history of how a country pushed to the edge of sovereign default managed to engineer a broad-based recovery through fiscal repair, banking-sector restructuring and institutional reform.

Ten years ago, Greek debt was rated junk, banks were shut and the stock market had lost more than 90% of its value.

Today, the sovereign carries investment-grade ratings across the board and the Athens Composite Index has achieved something few thought possible five years ago: it has outperformed the Nasdaq 100.

Whether the next five years will deliver the same kind of returns remains uncertain.

But for the first time in a generation, Greece is no longer a symbol of financial collapse. It is increasingly becoming a case study in recovery.
