The IITU share price (LSE: IITU) is currently trading at 2,801.00 GBX as of late March 2026, following a period of sector-wide consolidation in the global technology markets. As an exchange-traded fund (ETF) formally known as the iShares S&P 500 Information Technology Sector UCITS ETF, IITU provides investors with targeted exposure to the largest U.S. technology companies, including industry titans like NVIDIA, Apple, and Microsoft. Over the past 52 weeks, the fund has reached a high of 3,398.00 GBX and a low of 1,878.00 GBX, reflecting the high-growth yet volatile nature of the semiconductor and software industries. In this exhaustive guide, you will learn about the fundamental drivers of the IITU valuation, its expense ratio of 0.15%, and how the 2026 rebalancing of the S&P 500 Information Technology Index is shaping the fund’s future performance. Whether you are a long-term passive investor or a tactical trader, this analysis provides the scannable, factual data necessary to understand the trajectory of this £10.6 billion technology tracker.
IITU ETF Overview and Strategy
The iShares S&P 500 Information Technology Sector UCITS ETF (IITU) is a physically replicated fund designed to track the performance of the S&P 500 Capped 35/20 Information Technology Index. This index specifically isolates companies within the S&P 500 that are classified under the Information Technology sector, providing a concentrated bet on American innovation. The “Capped 35/20” rule is a crucial structural feature, ensuring that no single constituent exceeds 35% of the fund’s weight and the sum of all constituents with a weight over 5% does not exceed 50% of the total portfolio.
Managed by BlackRock, the world’s largest asset manager, IITU is an “accumulating” fund, meaning all dividends generated by the underlying tech stocks are automatically reinvested back into the fund’s Net Asset Value (NAV). This structure is particularly efficient for UK investors looking to maximize compound growth without the administrative burden of handling small dividend payments. With a Total Expense Ratio (TER) of just 0.15%, it remains one of the most cost-effective ways for European and UK investors to gain direct exposure to the Silicon Valley ecosystem.
Current Share Price Performance 2026
As of the close of trading on March 27, 2026, the IITU share price sits at 2,801.00 GBX, representing a year-to-date decline of approximately 9.8% from its January highs. This movement is largely attributed to a broader market “rotation” where investors have locked in gains from the 2025 AI-driven surge to seek value in lagging sectors. Despite the recent dip, the fund maintains strong long-term momentum, supported by a five-year annualized return that continues to outperform the broader S&P 500 index.
Technical analysis shows that IITU is currently testing a significant support level near the 2,800 GBX mark. Trading volume has remained robust, with over 264,000 shares changing hands in the most recent session, indicating high liquidity for both retail and institutional participants. Market analysts are closely watching the “Magnificent Seven” earnings reports scheduled for April 2026, as these results will likely determine if IITU can rebound toward its previous 52-week high of 3,398.00 GBX.
Analysis of Top Holdings
The performance of IITU is heavily dictated by a handful of high-conviction holdings that dominate the U.S. tech landscape. As of early 2026, the fund’s top five holdings account for approximately 66.76% of its total net assets, making it a highly concentrated investment vehicle.
NVIDIA (NVDA)
NVIDIA remains the largest constituent in the fund with a weight of 22.73%. Its performance is the primary engine for IITU’s price action, driven by the global demand for H100 and B200 AI chips. In 2025, NVIDIA saw a staggering 50.34% increase in valuation, which heavily bolstered the IITU share price during that period.
Apple Inc. (AAPL)
Apple holds the second-largest position at 18.58%. While it has faced regulatory challenges in Europe and slowing iPhone sales in certain regions, its massive services revenue and buyback programs provide a stabilizing “floor” for the ETF’s valuation. Investors view Apple as a defensive tech play within the IITU portfolio.
Microsoft Corp. (MSFT)
Microsoft carries a weight of 15.27% and is a key driver through its Azure cloud platform and integration of Copilot AI across its software suite. Unlike the hardware-focused NVIDIA, Microsoft provides IITU with exposure to high-margin recurring software revenue, though the stock has seen a moderate 8.66% pullback in early 2026.
Sector and Industry Exposure
While the fund is broadly labeled as “Technology,” its internal exposure is highly specialized. The largest sub-sector is Semiconductors, which currently represents 40.63% of the fund’s weight. This makes IITU particularly sensitive to global supply chain dynamics, export controls, and the capital expenditure cycles of major data center operators.
The second-largest segment is Technology Hardware, Storage & Peripherals (19.92%), followed by Systems Software (19.76%). This distribution means that while IITU is an “Information Technology” fund, it has zero exposure to “Communication Services” companies like Meta (Facebook) or Alphabet (Google), which are classified in a different GICS sector. Investors seeking exposure to the entire “Big Tech” spectrum often pair IITU with a Nasdaq 100 tracker to fill these gaps.
Historical Performance and Returns
Looking back over the last decade, IITU has been one of the highest-performing ETFs available on the London Stock Exchange. Since its inception in November 2015, the fund has delivered a cumulative total return exceeding 685% in USD terms. In 2023 and 2024, the fund posted back-to-back annual gains of 57.5% and 37.2%, respectively, fueled by the rapid adoption of generative artificial intelligence.
However, the fund is not without its “drawdown” periods. In 2022, IITU experienced a -28.4% decline as rising interest rates compressed the valuation multiples of growth stocks. The 2026 year-to-date performance (-9.8%) serves as a reminder that the tech sector is prone to sharp corrections following periods of exponential growth. Long-term investors typically view these pullbacks as opportunities to “dollar-cost average” into a sector with strong structural tailwinds.
Dividend Policy and Reinvestment
Because IITU is an Accumulating (Acc) fund, it does not pay out a cash dividend to its shareholders. Instead, the dividends paid by companies like Microsoft, Apple, and Broadcom are collected by the fund manager and used to purchase more shares of the companies within the index. This process is reflected in the rising Net Asset Value (NAV) of each IITU share.
For UK investors holding IITU in a taxable brokerage account, it is important to track the reported income (excess reportable income) for tax purposes, even though no cash was received. However, for those holding the fund within a Stocks and Shares ISA or SIPP, the accumulation feature is entirely tax-efficient, allowing the full value of the dividends to compound without any immediate tax liability.
Expense Ratio and Trading Costs
IITU is highly regarded for its low-cost structure, featuring an Ongoing Charge Figure (OCF) of 0.15%. This means that for every £10,000 invested, the annual management fee is approximately £15. This is significantly lower than actively managed technology funds, which can charge 1.00% or more while often failing to beat the benchmark index over long periods.
Beyond the management fee, investors should consider the “bid-ask spread” when trading on the London Stock Exchange. Due to the fund’s massive size (£10.6 billion), the spread is typically very narrow—often around 0.05% to 0.10%—meaning the cost to enter and exit a position is minimal. This liquidity makes IITU an ideal instrument for both large institutional blocks and small monthly retail contributions.
Future Outlook for 2026 and 2027
The outlook for the IITU share price in the second half of 2026 is cautiously optimistic, contingent on two primary factors: interest rate stability and AI monetization. As the U.S. Federal Reserve approaches the end of its current rate cycle, the “discount rate” applied to future tech earnings is expected to stabilize, which traditionally supports higher P/E multiples for the stocks within the IITU portfolio.
By 2027, analysts expect a second wave of growth driven by “Edge AI”—the integration of advanced processing power directly into consumer devices like laptops and smartphones. As Apple and other hardware manufacturers refresh their product lines to support these features, the Technology Hardware segment of IITU could see a significant revenue surge. However, investors must remain vigilant regarding antitrust litigations in the U.S. and EU, which target the fund’s largest holdings and could introduce headline risk.

IITU vs. IUIT: What’s the Difference?
Many investors are confused by the existence of two tickers for the same fund: IITU and IUIT. Both track the exact same iShares S&P 500 Information Technology Sector UCITS ETF and hold the same underlying assets. The only difference is the currency in which they are traded on the exchange.
IITU is traded in British Pounds (Pence/GBX), making it the preferred choice for UK-based investors who want to avoid foreign exchange conversion fees at the point of trade. IUIT is traded in US Dollars (USD) and is often used by international investors or those with USD-denominated accounts. It is important to note that even if you buy IITU in Pounds, you still have “hidden” currency exposure to the USD, as the underlying stocks (NVIDIA, Apple, etc.) are priced in Dollars.
Structure and underlying assets
IITU is an accumulation UCITS ETF, domiciled in Ireland, with iShares (BlackRock) as the manager and BlackRock as the index‑provider. The ETF tracks the S&P 500 Information Technology Sector Index, which is a sub‑sector index of the S&P 500 focusing solely on companies classified in the Information Technology sector according to the Global Industry Classification Standard (GICS).
The underlying index typically holds around 70–80 names, heavily concentrated in mega‑cap US tech giants such as leading software, cloud, and semiconductor companies. The ETF is fully replicating, meaning it directly purchases the constituent stocks in roughly the same weights as the index, rather than using synthetic derivatives. This structure keeps tracking error low but exposes investors to the sector‑specific risks and concentration of the S&P 500 tech sector.
Top holdings and weightings
Top holdings in the underlying index usually include large‑cap software and hardware platforms, cloud‑infrastructure providers, and semiconductor manufacturers, with the top 10 stocks often accounting for more than half of the portfolio. This concentration means that the ETF’s share price is heavily influenced by the performance of a handful of mega‑cap names, even though the fund is diversified across multiple companies.
Because the ETF is market‑cap‑weighted, bigger companies naturally dominate the index and, therefore, the ETF’s price behaviour. A positive earnings surprise from one of the largest names can lift the entire index by several basis points, while a negative surprise can drag the ETF lower, even if other holdings are stable. Investors using IITU should therefore think of it as a concentrated bet on the largest US tech stocks, rather than a diversified cross‑sector portfolio.
How the price is formed
The share price of IITU is ultimately driven by the NAV of its underlying basket of S&P 500 tech stocks, plus a small spread related to trading and market‑makers’ spreads. The ETF’s creation‑redemption mechanism allows authorised participants to swap baskets of underlying shares for ETF units (and vice versa), which keeps the market price tightly aligned with the NAV.
On the London exchange, the price is quoted in GBP, reflecting the GBP‑converted value of the USD‑denominated underlying NAV. Currency‑rate movements between GBP and USD can therefore influence the quoted price on LSE, even if the underlying US stocks are flat in their own currency. For investors, this means that FX risk is a secondary but real factor alongside sector and equity risk.
Performance and risk profile
IITU has delivered strong long‑term performance, reflecting the outperformance of the S&P 500 Information Technology sector versus broader markets over the past decade. Over the 1‑year period to early 2026, the ETF typically shows a total return in the mid‑teens to low‑twenties percent, following a deep 2025 drawdown. Over longer horizons (3–5 years), performance is often significantly higher, driven by the earnings and valuation expansion of the underlying tech giants.
However, this performance comes with elevated volatility and drawdown risk. The ETF’s standard deviation and beta to global markets are high, meaning it can lose or gain value rapidly in changing macro or tech‑sector conditions. The 2024–2025 decline of roughly 40–45% from peak to trough highlights how even a well‑constructed, highly liquid sector ETF can experience severe drawdowns in tightening‑monetary‑policy environments.
Growth vs. volatility
For growth‑oriented investors, IITU offers direct exposure to the leading US tech ecosystem, including cloud, AI‑infrastructure, and software platforms that are reshaping the global economy. This exposure can generate multi‑year compound growth when the sector is in a favourable regime, especially if investors dollar‑cost‑average rather than time the top or bottom.
On the flip side, the ETF’s concentration in high‑multiple growth names makes it vulnerable to multiple‑contraction shocks when interest‑rates rise or growth expectations reset. In such periods, the ETF can underperform broader indices and even cash for extended stretches, testing the discipline of long‑term holders. Investors should therefore balance IITU with other sectors and asset classes in a diversified portfolio.
Risk‑management considerations
Because IITU is a sector‑specific, accumulation ETF, it is not suitable as a core, low‑volatility holding for conservative investors. Practical risk‑management steps include limiting the ETF’s weight in your portfolio, using dollar‑cost‑averaging rather than lump‑sum timing, and pairing it with defensive assets such as bonds, cash, or broader‑market ETFs.
For active traders, stop‑loss or target‑price discipline can help manage intraday and intraweek volatility, while position‑size control prevents over‑exposure to tech‑sector risk. Given that the ETF’s price can move tens of pence in a single session, especially during US‑session‑driven London‑trading hours, investors should align their use of IITU with their risk tolerance, time horizon, and broader asset‑allocation strategy.
How to buy and use IITU
Buying IITU shares is mechanically similar to buying a stock: you open a brokerage account that supports LSE listings, deposit funds (usually in GBP), and then search for the ticker IITU on the platform. The price you see is quoted in GBX pence, with the prevailing market price around 2,800–2,850 pence per share, and the minimum trade size typically one share (though brokers may impose minimum order‑values).
Brokerage and account setup
Most UK‑based and many international brokers list IITU as an ETF on the London exchange, often under the full name “iShares S&P 500 Information Technology Sector UCITS ETF – IITU”. After logging in, you can place market orders (executed at the current price) or limit orders (set at a specific GBP), and review the ETF’s NAV, expense ratio, and holdings via the broker’s research tools.
Fees vary by platform, but generally include deal commissions or per‑trade charges, sometimes offset by zero‑commission deals on certain ETFs or subscription‑based pricing. The ongoing charge (OCF) for IITU is around 0.15% per year, which is typical for a large, liquid UCITS ETF and is deducted from the NAV rather than appearing as a visible bill to the investor.
Strategic use in portfolios
IITU is best used as a sector‑tilting or satellite holding, rather than a core diversified equity fund. For investors seeking overweight exposure to US tech, the ETF provides a low‑cost, liquid, and transparent way to implement that view without the complexity of picking individual stocks.
In a diversified portfolio, IITU can be paired with broad‑market global or UK‑focused ETFs, bond funds, and cash, so that the tech‑sector’s higher volatility does not dominate overall risk. Because it is an accumulation‑style ETF, investors should focus on total return (price appreciation) rather than income, making it suitable for growth‑oriented, long‑term investors willing to ride sector‑specific cycles.
Practical information for investors
For anyone considering IITU, the costs, liquidity, and trading mechanics matter as much as the sector exposure. The ETF trades on the London Stock Exchange during normal LSE hours, with real‑time or near‑real‑time pricing available on most mainstream brokers. The expense ratio of about 0.15% is competitive for a sector‑specific UCITS ETF, and the fund size exceeding £10 billion ensures robust liquidity and tight spreads.
Trading hours and costs
IITU trades on the LSE Main Market during standard hours, typically 08:00–16:30 UK time, with prices updating in line with the underlying S&P 500 tech index and prevailing GBP/USD FX rates. Because the ETF holds USD‑denominated assets, there is a small FX cost embedded in the price movement, though this is usually minor compared with the equity‑sector volatility.
Costs to the investor include broker commissions or per‑trade charges and the built‑in 0.15% OCF, which is already reflected in the NAV and quoted price. There is no explicit dividend payout, since the ETF is accumulation‑style, so all income is reinvested automatically. This structure suits long‑term holders who prefer compounding returns over regular cash distributions.
Tax and residency considerations
For UK investors, IITU is typically treated like any other offshore UCITS ETF, with capital gains subject to UK Capital Gains Tax rules and the accumulated income not creating an annual dividend‑tax event. Some investors may hold IITU within ISAs or SIPPs, where the tax treatment differs: within an ISA, capital gains and reinvested income are generally tax‑free, while SIPPs convert future gains into retirement‑taxation brackets.
Non‑UK residents should review their local tax rules on UCITS ETFs, foreign‑equity gains, and currency‑gains, as tax regimes can vary significantly and may impact the net return from an IITU position. Professional tax advice is recommended before taking large or long‑term positions in the ETF, especially when using leveraged or derivative‑based products linked to IITU.

Final Thoughts
IITU share price as of March 2026 reflects both the immense growth potential and the inherent volatility of the global technology sector. While the fund has experienced a period of consolidation following the historic AI-driven highs of 2025, its fundamental structure remains one of the most efficient ways for investors to capture the long-term appreciation of U.S. innovation. With a 0.15% expense ratio and a portfolio dominated by cash-rich leaders like NVIDIA, Apple, and Microsoft, IITU continues to serve as a cornerstone for growth-oriented investors within the UK and Europe.
Looking ahead toward 2027, the trajectory of the iShares S&P 500 Information Technology Sector UCITS ETF will be closely tied to the successful monetization of artificial intelligence and the stability of the macroeconomic environment. For the patient investor, periodic pullbacks toward the 2,800 GBX support level may offer strategic entry points into a sector characterized by high margins and structural tailwinds. As the digital economy continues to evolve, IITU remains a premier vehicle for those looking to diversify away from domestic markets and participate in the ongoing technological revolution.
