Investors deciding how to compare exchange-traded funds face a larger and more complicated product market than they did even two years ago. As of mid-July 2026, issuers had launched 1,084 ETFs, only 77 fewer than the record 1,161 products introduced during all of 2025, according to Morningstar data.
Many of the new funds bear little resemblance to the broad index trackers that established the industry. Almost one-quarter of 2026 launches were leveraged single-stock ETFs, compared with 20% in 2025 and 4% in 2024. Other launches covered narrow artificial-intelligence themes, options strategies, active portfolios and alternative versions of familiar benchmarks.
The expansion gives investors more choice, but it also makes comparison harder. Similar names can conceal different holdings, weighting rules, volatility profiles and tax structures. A fund with the strongest recent return may simply have taken more risk, while the cheapest ETF may track a narrower or more concentrated portfolio.
A useful ETF comparison therefore begins with the role the fund is expected to perform. The next step is examining whether its portfolio, risk and structure can deliver that exposure efficiently.
ETF Launches Are Approaching the 2025 Record
The pace of launches shows how quickly issuers are responding to market themes. By mid-July, the industry was already within 6.6% of the full-year record set in 2025.

The volume of products does not mean every launch will gather lasting demand. The Financial Times reported that one new issuer expected roughly 20% of its funds to collect 80% of its assets, reflecting a business model based on launching many strategies and relying on a small number of winners.
Investors need a different process. Rather than starting with the newest theme or the best recent return, they should compare funds that are intended to serve the same portfolio function.
How to Compare ETFs Using Nukoud
Nukoud’s ETF Compare tool allows users to place as many as four ETFs side by side. The comparison covers key statistics, historical performance, one-year standard deviation, fees and general fund information.
The feature works best when the selected funds provide broadly similar exposure. Comparing four S&P 500 ETFs can reveal differences in fees, fund scale and performance delivery. Placing a broad-market fund beside a semiconductor ETF may still be informative, but the comparison then measures two different investment strategies rather than identifying the more efficient version of the same exposure.
The tool should be treated as the beginning of the analysis rather than a system for declaring one universal winner. Each category answers a different question.
Start With Exposure Rather Than Recent Performance
An ETF’s name is marketing shorthand. It may describe a broad market, industry or theme without showing how the portfolio is constructed.
Two technology ETFs can hold different companies and assign radically different weights to their largest positions. One may be dominated by megacap software and semiconductor businesses, while another focuses on smaller hardware suppliers or uses an equal-weighting rule. Their returns can diverge even though both carry “technology” in the name.
Investors should compare the number of holdings, sector allocation, geographic exposure and concentration in the largest positions. The Securities and Exchange Commission’s investor guidance recommends checking whether a fund’s disclosed holdings remain consistent with its name, objective and stated strategy.
Compare the Index Rules or Active Mandate
Passive ETFs follow an index, but indices are constructed through deliberate choices. Market-cap weighting gives the largest companies the greatest influence. Equal-weighting reduces that influence and increases exposure to smaller constituents. Other methodologies use revenue screens, volatility measures, dividend criteria or concentration caps.
An active ETF requires examination of the manager’s mandate. Investors should understand the eligible investment universe, use of derivatives, portfolio limits and circumstances under which the manager can hold cash.
Comparing performance without comparing these rules can produce the wrong conclusion. The fund with the highest return may simply own a more concentrated or aggressive portfolio.
Compare Performance Over Identical Periods
Performance comparisons should use the same dates and the same return convention.
A one-year total return should not be compared with another fund’s year-to-date price return. Total return includes distributions, while price return reflects only the change in the ETF’s market value. Investors should also distinguish between net asset value performance and market-price performance when spreads or premiums have affected execution.
Recent results need context. A sector fund may outperform during a technology rally and lag when leadership changes. Historical performance shows how a strategy behaved during a particular market period. It does not establish which ETF will lead next.
A useful comparison asks whether the return difference came from the index, security selection, currency exposure or tracking quality. That distinction separates portfolio design from fund execution.
How to Compare Bond and Sukuk ETFs
Fixed-income ETFs show why comparing recent performance alone can produce a misleading result.
The iShares iBoxx $ Investment Grade Corporate Bond ETF, ticker LQD, tracks U.S. dollar-denominated investment-grade corporate bonds. The iShares $ Sukuk UCITS ETF, ticker SKUK, follows an index of U.S. dollar-denominated emerging-market sukuk. Both can provide portfolio income, yet they differ in legal structure, geography, issuer mix and sensitivity to interest rates.
A GCC investor could also examine the Lunate JP Morgan Global Sukuk ETF, ticker SUKUK, which is listed on Abu Dhabi Securities Exchange. The fund tracks the J.P. Morgan Global Investment Grade Sukuk Index, covering liquid U.S. dollar-denominated sovereign, quasi-sovereign and corporate sukuk with at least $500 million outstanding.
These funds may appear beside one another in a fixed-income search, but their returns should not be interpreted as evidence that one manager is automatically better. LQD’s result is driven largely by U.S. corporate credit spreads and Treasury yields. SKUK and SUKUK also reflect emerging-market risk, sovereign exposure, sukuk-market liquidity and the geographic composition of their benchmarks.
What a Bond and Sukuk ETF Comparison Should Show
The Alinma fund tracks the iBoxx Tadawul SAR Government Sukuk 0-5 Index, which limits eligible Saudi government sukuk to securities with five years or less remaining at entry. Albilad’s sovereign sukuk ETF is also listed on the Saudi Exchange and continued publishing distributions and portfolio updates during 2026.
Compare Duration Before Comparing Returns
Duration should be one of the first statistics checked across bond and sukuk ETFs. A fund with longer duration will generally move more when benchmark yields change.
For example, SKUK reported an effective duration of 3.98 years and a weighted average maturity of 4.93 years as of July 22, 2026. A one-percentage-point increase in comparable yields would imply an estimated price decline of roughly 4%, before income, credit-spread changes, fees and convexity.
A lower standard deviation may therefore reflect shorter duration, greater sovereign exposure or a calmer currency and rate environment. It does not necessarily mean the ETF is better managed.
Use Standard Deviation to Compare Risk Alongside Return
Nukoud’s comparison feature includes one-year standard deviation, which measures how widely an ETF’s returns have moved around their average during the period.
A higher figure indicates greater historical fluctuation. Two ETFs may generate similar returns, but one may have subjected investors to much larger price swings. Conversely, a high-return fund with a high standard deviation may have rewarded greater risk rather than delivered superior efficiency.
The measure should not be used in isolation. One year may contain an unusual rally, commodity shock or regional selloff. Standard deviation also treats upside and downside movements equally, even though investors usually view them differently.
It remains useful when comparing funds with similar objectives. A material volatility gap can point toward differences in concentration, leverage, currency exposure or index construction.
Compare Fees With the Total Cost of Ownership
The expense ratio is the clearest recurring cost, but it is not the only cost.
Investors also face the bid-offer spread, brokerage charges, tracking difference and possible tax leakage. A fund charging 0.10% a year can be more expensive for a short-term investor than a rival charging 0.20% if the cheaper fund trades with a much wider spread.
The SEC describes the bid-ask spread as a hidden cost because an investor buys at the higher ask price and sells at the lower bid price. Fund websites generally publish the median spread, allowing investors to compare this cost across similar products.
Tracking difference provides another test. An ETF will usually trail its index by at least part of its fee. A persistent shortfall beyond that amount can arise from transaction costs, portfolio sampling, withholding taxes or inefficient implementation.
Holding Period Changes Which Cost Matters Most
Long-term investors are usually more sensitive to annual fees because those charges compound over many years. Frequent traders should place greater weight on spreads and market impact.
State Street’s analysis of total ownership cost notes that trading costs can outweigh small expense-ratio differences when positions are traded or rebalanced frequently.
Check Fund Size, but Do Not Treat It as a Liquidity Score
Assets under management show whether an ETF has attracted capital and may help indicate its commercial durability.
A commonly cited sustainability reference is $50 million, although the amount required for break-even differs across issuers and strategies. State Street reported that 38% of ETFs remained below that level when its due-diligence analysis was published.
The threshold is not a pass-or-fail rule. A specialist ETF may remain open with fewer assets if the issuer views it as strategically important. Another fund can close despite holding more than $50 million if growth stalls or the provider restructures its product range.
Investors should examine the direction of assets rather than one static number. A small ETF receiving steady creations may have a clearer route to scale than a larger fund suffering persistent withdrawals.
Separate Seed Capital From Organic Demand
Launch assets may be supplied by the issuer, an affiliate or an institutional seed investor. That capital allows the ETF to form its initial portfolio and begin trading.
Early AUM therefore does not necessarily represent widespread investor adoption. Continued asset growth and repeated creations provide stronger evidence that the product has found a market.
A Small ETF Is Not Automatically Illiquid
Fund size, screen volume and liquidity measure different features.
An ETF with limited daily trading can still accommodate a larger order when its underlying securities are liquid. Authorized participants can create new ETF shares by delivering securities or cash to the fund, linking the product’s capacity to the liquidity of the portfolio beneath it.
The reverse can also occur. A fund may show active exchange trading but hold securities that are difficult to price during stress or when the underlying market is closed.
Investors should compare the spread, quoted market depth, premiums or discounts to net asset value and the liquidity of the underlying holdings. Investor.gov advises checking fund websites for spreads, portfolio holdings and premium-discount information before trading.
Examine Fund Information and Closure Risk
Fund information identifies the issuer, investment objective, domicile and legal structure behind the ticker.
Issuer commitment matters because an ETF is also a commercial product. Investors should consider the provider’s distribution reach, ETF experience and reason for maintaining the strategy. An established issuer does not guarantee that every product will survive, but a fund should have a credible path toward gathering assets.
When an ETF closes, investors can generally sell before the final trading date or remain invested and receive cash after the portfolio is liquidated. The process can create transaction costs, an unwanted taxable event or a gap while the investor searches for replacement exposure.
Closure risk deserves more attention when a fund has remained small for an extended period, has lost most of its seed assets or duplicates several larger competitors.
What GCC Investors Should Add to the Comparison
For UAE and Saudi investors, domicile can change the result even when two ETFs track similar markets.
A U.S.-domiciled fund, an Irish Undertakings for Collective Investment in Transferable Securities ETF and a locally listed GCC product may differ in dividend withholding, estate-tax treatment, distribution policy and trading liquidity.
U.S.-source income paid to a nonresident is generally subject to 30% withholding unless a treaty provides a lower rate. The Internal Revenue Service also requires an estate-tax filing when a nonresident noncitizen dies with more than $60,000 of U.S.-situated assets, subject to applicable treaties and individual circumstances.
Sharia compliance requires a separate comparison. A technology or healthcare ETF is not automatically permissible because the portfolio may include companies that fail business-activity or financial-ratio screens. Investors should examine the screening methodology, named Sharia supervisory body, purification policy and use of leverage or derivatives.
A GCC listing can simplify custody and settlement, but local access does not remove the need to compare spreads, fund structure and the liquidity of the primary market.
The ETF Comparison Checklist
The 2026 ETF launch boom has made choosing a ticker easier and choosing the right fund harder. Nukoud’s ETF Compare tool lets investors place up to four products side by side across key statistics, performance, one-year standard deviation, fees and fund information. The most useful outcome is not a single winner. It is a clearer view of which fund’s exposure, risk and structure match the job it is expected to perform.
