The Giant iShares Nasdaq 100 ETF: Size, Cost, and Recent Returns

The iShares Nasdaq 100 UCITS ETF (Acc) is Europe’s largest exchange-traded fund tracking the Nasdaq 100, with assets of €22.3 billion. Launched in January 2010, it physically replicates the index of the 100 biggest non-financial companies listed on the Nasdaq—a roster dominated by hardware, software, telecoms, e-commerce and biotech. At 0.30% per year, its ongoing charge is in line with most top-five peers, though the Amundi Core Nasdaq 100 Swap UCITS ETF undercuts it at 0.22%. What investors get in return is unmatched scale and liquidity, plus the comfort of a well-established issuer in iShares (BlackRock).

The fund’s performance illustrates both the power and the pain of concentrated tech bets. After crashing 28.5% in 2022—when rapid Fed rate hikes hammered high-growth valuations—the ETF soared 49.1% in 2023 and 33.3% in 2024 on the AI boom. Gains then tapered to just 6.6% in 2025, before accelerating again to 13.5% in the current year. The top ten holdings now command 47.4% of assets, led by NVIDIA (8.14%), Apple (7.27%) and Microsoft (5.30%), companies whose value rests on continued innovation and massive AI infrastructure spending.

The fund’s higher volatility—23.1% annualised over five years—reflects that concentration and the exclusion of the usually more stable financial sector. Its maximum drawdown of 31.43% was set in 2022, a reminder that even a fund with a long bull-run can suffer deep, sudden losses.

Why the ETF’s Gains Shrank—and Why They’re Accelerating Again

The AI Boom’s Early Fireworks and the Base Effect

The eye-watering returns of 2023 and 2024 were powered by the first wave of AI-driven spending, when the market repriced the entire semiconductor and cloud ecosystem. As share prices jumped, the same absolute earnings growth translated into smaller percentage gains—a classic “base effect.” The 2025 near-stall, at 6.6%, did not signal a collapse in profits; rather, it reflected an already elevated starting point. NVIDIA’s dominance, for example, saw its share price multiply, but keeping up triple-digit growth rates becomes arithmetically harder as the denominator swells.

Rate Cuts Rekindle Appeal

The 2026 rebound owes much to a shift in the interest-rate backdrop. The US Federal Reserve’s rate cuts, already underway, reduce the discount applied to future earnings—making high-growth technology stocks relatively more attractive compared with bonds. Meanwhile, record capital expenditure announcements from the largest cloud and AI players (Microsoft, Amazon, Alphabet) are flowing directly into NVIDIA’s order book, giving the fund’s top holding a renewed lift. Analysts note that if the rate-cutting cycle continues, it could provide a supportive environment for the entire Nasdaq 100, though any unexpected hawkish turn from the Fed would immediately test the thesis.

Concentration: The Double-Edged Sword

With almost half the fund in just ten stocks and zero exposure to financials, the ETF behaves very differently from a broader US or global benchmark. The five-year volatility of 23.1% is markedly higher than a world ETF, and the maximum loss of 31.43% equals the worst peak-to-trough in the fund’s entire history. That extreme concentration makes it a poor choice as a standalone core holding; instead, it functions as a high-octane satellite for investors willing to endure substantial swings for the chance of outsized long-term growth.

When This Tech-Heavy ETF Makes Sense in a Portfolio

  • Use as a satellite, not a core. If your portfolio is already diversified with a global or S&P 500 ETF, allocating 10–20% to this fund can add targeted tech exposure. But relying on it as a primary holding means accepting extreme concentration and a historical 30%-plus drawdown risk.
  • Compare costs before buying. At 0.30% TER, the iShares ETF is not the cheapest. The Amundi Core Nasdaq 100 Swap UCITS ETF charges 0.22% and may suit cost-focused investors. The iShares fund, however, offers superior liquidity and a 15-year track record—valuable for larger trades.
  • Stress-test your risk tolerance. The 2022 drawdown of 28.5% in a single year (and a peak-to-trough maximum of 31.43%) is a real scenario, not a theoretical one. If a repeat would force you to sell at the bottom, this ETF is not for you.
  • Watch NVIDIA earnings and cloud capex. Given the fund’s heavy AI tilt, quarterly results from NVIDIA and capex guidance from Microsoft, Amazon and Alphabet act as near-term leading indicators for the ETF’s direction.
  • Factor in euro-dollar movements. The ETF is denominated in euros, but the underlying stocks trade in dollars. A strengthening euro relative to the dollar would reduce returns for euro-based investors, while a weaker euro adds a tailwind.
