Why GPIX Beat JEPI Despite Similar Income Yields

10x Genomics delivered the largest single boost to ARK Invest's exchange-traded funds in the third quarter, while Tesla was the most persistent drag. The contrast matters because ARK's attribution data shows how position size and stock performance combined inside the funds, not simply which shares rose or fell the most.

10x Genomics contributed 9.03 percentage points to the ARK Genomic Revolution ETF's 28.92% quarterly return and 2.92 points to the ARK Innovation ETF's 10.39% gain. ARK linked the advance to stronger investor interest in single-cell sequencing and spatial analysis as data sources for AI-assisted drug discovery. The firm also highlighted orders for the new Atera spatial system, with 40 shipments expected during 2026.

Other life-sciences holdings made sizable contributions. Twist Bioscience added 6.51 points to ARKG and 2.55 points to ARKK after its shares rose 87.83% during the quarter. Tempus AI contributed 3.21 points to ARKG and 2.08 points to ARKK as its stock gained 41.38%. Those figures make clear that the biotechnology exposure was not a one-stock story, although the group remains sensitive to expectations for AI-driven research spending.

Palantir was the broadest winner across the family. It added between 1.47 and 2.39 percentage points to five ARK funds, including ARKK, ARKQ, ARKW, ARKF and ARKX. Nvidia made smaller positive contributions to the autonomous-technology and space funds.

Tesla moved in the opposite direction. Tesla subtracted 1.75 points from ARKK, 1.72 points from ARKQ and 1.43 points from ARKW. ARK cited weak profitability after Tesla's second-quarter results, price cuts and the wind-down of Model S and Model X, while also noting a later recovery tied to the Cybercab launch in Austin. Rocket Lab reduced ARKX's return by 2.04 points and ARKQ's by 1.39 points.

The central lesson is concentration. ARK's thematic funds can produce strong returns when several high-conviction holdings move together, but the same construction can magnify setbacks. Investors comparing ARK funds should look past the headline return and examine which positions supplied it, because a few holdings accounted for a large share of both the upside and the drag.

SOXQ won the most recent year, but SMH still dominated the full period in which both semiconductor funds have operated.

The original comparison calculated that the Invesco PHLX Semiconductor ETF returned 67.69% over the year beginning October 16, 2025, with distributions reinvested. The VanEck Semiconductor ETF returned 61.32%, leaving SOXQ ahead by 6.37 percentage points. In 2026 through the comparison date, SOXQ also led by 7.44 points.

The five-year ranking was the opposite. From October 15, 2021, SMH returned 333.41% versus 256.91% for SOXQ, a gap of 76.5 percentage points. SOXQ launched in June 2021, so there is no ten-year record for a clean side-by-side comparison.

Index construction explains why leadership can reverse. SOXQ tracks the PHLX Semiconductor Sector Index, a modified market-capitalization-weighted portfolio of large U.S.-listed semiconductor businesses. SMH follows a different index of large, liquid semiconductor companies. Different eligibility, weighting and rebalancing rules create different exposure to the stocks leading each phase of the chip cycle.

Both funds remain concentrated sector bets. A switch from SMH to SOXQ changes the portfolio weights, but it does not remove exposure to semiconductor demand, capital spending, export controls or the valuation of AI-related stocks. Recent gains above 60% also raise the consequence of a cyclical reversal.

Costs and taxes can outweigh a small expected performance difference. Selling SMH after a large gain in a taxable account may trigger capital-gains tax. An investor using new contributions can change future exposure without realizing the entire existing gain. Fractional-share trading also makes the difference in share price less important than it once was.

The return figures come from the original same-date calculation, while investors should use issuer pages for current official performance and holdings. Short windows can be useful for understanding which index is working, but they are weak evidence that the advantage will persist.

SOXQ's recent lead is real within the measured window. SMH's longer record is stronger by a much larger margin. The choice should rest on index exposure, concentration limits and tax cost, not on assuming that either the one-year or five-year winner must keep winning.

A large five-year return gap between HDV and NOBL looks decisive until the comparison is extended to ten years.

The original analysis calculated reinvested total returns of 82.92% for the iShares Core High Dividend ETF and 37.22% for the ProShares S&P 500 Dividend Aristocrats ETF over the five years through October 2026. Over ten years, however, the results were almost tied: 172.65% for HDV and 171.96% for NOBL. The contrast shows how strongly the chosen start date can shape an ETF ranking.

The funds screen for different qualities. HDV seeks exposure to relatively high-dividend U.S. companies and uses Morningstar's dividend-yield-focused index methodology. BlackRock reported an expense ratio of 0.08% and a 30-day SEC yield of about 3.05% at September 30, 2026. NOBL tracks companies in the S&P 500 that have increased dividends for at least 25 consecutive years. ProShares charges 0.35%.

That distinction changes portfolio behavior. HDV can concentrate in mature, cash-generative sectors when their yields are attractive. NOBL's dividend-growth requirement favors durability but can lag when high-yield sectors lead or when its equal-weighted portfolio is out of favor. Neither methodology guarantees better future returns.

Recent performance favored HDV as well. The source comparison put HDV ahead over the prior month, year to date and the trailing year. Investors should still verify current issuer performance because daily market returns and reinvestment assumptions can alter the exact figures.

Yield is only one part of the decision. A higher starting yield may suit an investor who needs current income, while a long record of dividend increases may suit someone emphasizing business resilience and future income growth. Sector weights, valuation, tax consequences and existing holdings can matter more than a recent leaderboard.

Switching after a large run creates another risk. Selling NOBL in a taxable account can realize gains, and buying HDV after a period of outperformance may amount to chasing the sectors that just worked. The nearly identical ten-year outcome is a useful restraint: different strategies can reach similar long-term results through very different market cycles.

DVY and JEPI are often grouped together as income funds, but their five-year records reflect two very different jobs.

The original comparison calculated that a dividend-reinvested investment in the iShares Select Dividend ETF returned 58.53% over the five years through October 20, 2026, versus 43.22% for the JPMorgan Equity Premium Income ETF. DVY also led over the prior year and in 2026 through that date, while JEPI performed better over the most recent month. These point-to-point figures can change quickly and are not a substitute for issuer-reported month-end performance.

The income comparison went the other way. Based on the distributions used in the original analysis, $100,000 invested for the trailing year generated about $7,992 from JEPI and $3,390 from DVY. JEPI paid monthly and DVY paid quarterly. That gap explains much of JEPI's appeal to investors who need cash flow now.

The funds produce income differently. DVY tracks an index of relatively high-dividend U.S. companies, so its return depends mainly on the stocks it owns and their dividends. JEPI actively owns U.S. large-cap stocks and uses an options-linked strategy to generate additional monthly income. JPMorgan's September 2026 fact sheet reported a 12-month rolling dividend yield of 8.04% and a five-year annualized NAV return of 7.78%.

Higher distributions are not automatically higher economic return. JEPI's option income can soften volatility and support cash payments, but it can also surrender some upside during strong equity rallies. DVY offers more direct participation in its dividend-stock portfolio and can be more sensitive to sector concentration and value-stock cycles.

Taxes can widen the practical difference. JEPI distributions may include income with different tax treatment from qualified stock dividends, while selling either fund can realize capital gains. Account type and an investor's own tax situation therefore matter as much as the headline yield.

JEPI launched in May 2020, so a clean ten-year comparison does not exist. The available history shows a trade-off, not a universal winner: DVY compounded more over the measured five-year window, while JEPI delivered much more current income. Investors should choose the return pattern they need rather than treating the largest distribution as the largest return.

JEPI's monthly distributions can complicate tax-loss harvesting when automatic reinvestment is active in a taxable account. The issue is not the payment itself. It is the purchase of additional JEPI shares inside the wash-sale window.

IRS Publication 550 says a wash sale can occur when an investor sells securities at a loss and buys substantially identical securities within 30 days before or after the sale. A dividend reinvestment purchases more shares of the same fund, so it can meet that condition.

The effect is usually partial rather than all-or-nothing. If a reinvestment buys fewer shares than the investor sold, the IRS matching rules apply the wash-sale treatment to the corresponding number of shares. The remaining sold shares may still generate a currently deductible loss, subject to the investor's broader tax circumstances.

The source used JEPI's October distribution to illustrate the scale. A distribution of $0.34134 per share reinvested near $57.12 would purchase shares equal to roughly 0.598% of the original position. More than one monthly purchase can fall inside the 61-day period surrounding a sale, so the affected slice can be larger.

A disallowed loss is generally added to the basis of the replacement shares, and the holding period carries over. That defers the deduction until those replacement shares are sold and creates additional recordkeeping. Investors should rely on their broker's records but still verify lots, because accounts at different brokers or an IRA purchase can complicate reporting.

The practical precaution is to turn off automatic reinvestment before a planned harvest and keep it off through the relevant window, while checking actual trade and reinvestment dates. Simply selling midway between monthly payments may not create enough distance on both sides.

This issue matters only when shares are sold at a loss in a taxable account. It does not make JEPI's monthly distribution policy defective, and tax-loss harvesting may not be suitable for every investor. Because wash-sale rules are fact-specific, investors with multiple accounts or large deductions should consult a qualified tax professional.
