Cathie Wood and ARK Invest: What the Record Shows
Cathie Wood is the founder, CEO and chief investment officer of ARK Investment Management, which she registered with the SEC in January 2014. Her flagship fund, the ARK Innovation ETF (ARKK), is actively managed and concentrated in companies ARK links to disruptive innovation.
Cathie Wood is one of the most quoted fund managers of the last decade, and much of what is said about her is opinion in one direction or the other. This page sticks to what ARK publishes about itself and what the fund’s own price history shows. It is not a view on whether to own the fund.
How it works
ARK’s own biography is the starting point. Catherine D. Wood “registered ARK Investment Management LLC … as an investment adviser with the U.S. Securities and Exchange Commission in January 2014,” it says, and as chief investment officer she “has ultimate responsibility for investment decisions.”
Before ARK, the same page says, she spent twelve years at AllianceBernstein as CIO of Global Thematic Strategies, and earlier 18 years at Jennison Associates.
The approach is thematic and active. ARK’s fund page describes ARKK as “an actively managed Exchange Traded Fund” that invests at least 65% of its assets in companies “relevant to the Fund’s investment theme of disruptive innovation.” ARK defines that as “the introduction of a technologically enabled new product or service that potentially changes the way the world works.”
So the manager does the choosing, not an index. That is the opposite of a fund that tracks a list of companies set by rules. A growth investing approach taken to its end, it accepts heavy swings in exchange for owning a small number of companies ARK expects to grow fast.
The fund page lists nine areas it draws from, from intelligent devices and autonomous mobility to digital assets and multiomic technologies. Any of those can fall out of favor at the same time, which is the practical meaning of a theme.
What ARKK holds
The fund details on ARK’s page are dated 31 Aug 2026. Net assets of $5,562 million, a typical holding count of 35 to 55, and an expense ratio of 0.75%. On a hypothetical $10,000 holding, 0.75% is $75 a year, taken inside the fund rather than billed.
Its top ten holdings, dated 25 Sep 2026, start with Tesla at 9.17% of the fund. Space Exploration Technologies was 5.90%, Tempus AI 5.89% and Circle Internet Group 5.03%. The ten together were 49.74%, adding the ten weights ARK lists, so half the fund sat in ten names.
ARK posts the full holdings list as a downloadable file on the same page, dated 25 Sep 2026 when read. That openness is unusual for an active manager, and it means the portfolio can be checked rather than guessed at.
The regional split, as of 31 Aug 2026, was 94.19% North America. A fund built on one theme, in one region, with half its weight in ten stocks is concentrated three ways at once.
The 2021 peak and the fall
The price history makes the concentration visible. By Yahoo Finance’s daily closes, ARKK peaked at $156.58 on 12 Feb 2021. Its lowest close after that was $29.64 on 28 Dec 2022, a fall of 81.07%.
ARK’s own calendar-year table agrees on the size of 2022. The fund page, read 25 Sep 2026, lists a 2022 NAV total return of -66.99% and a market-price return of -66.97%, and 2023 at 67.82% on NAV. The Yahoo closes give the same -66.97% for 2022 and 67.64% for 2023, matching ARK’s market-price column.
One year differs, and the reason is known. For 2021 ARK shows -23.38% at market price, while the closes give -24.02%. The closes count price only and leave out distributions, so a payout in that year accounts for the gap.
A worked example
Take a hypothetical $10,000 bought at the close of 12 Feb 2021, at $156.58. At the close of 28 Dec 2022, $29.64, it was worth $10,000 times 29.64 divided by 156.58, which is $1,892.96.
The climb back is the harder number. To return from $29.64 to $156.58 the price has to rise by 156.58 divided by 29.64, minus 1, which is 428.27%. A loss of 81.07% needs a gain of more than five times its own size to undo.
By the close of 24 Sep 2026, $91.70, the same $10,000 stood at $5,856.43. That is 41.44% below where it began, more than five and a half years later, before any distributions.
The same fund, bought at a different moment, tells another story. $10,000 at the first close in the file, $20.38 on 31 Oct 2014, would have been $44,995.09 at $91.70. Both are real. The difference is entry timing, which is why a single return figure for a volatile fund says little about any one holder.
The original data
The data: ARKK’s daily close for 2,991 days of trading, from 31 Oct 2014 to 24 Sep 2026, downloaded from Yahoo Finance on 25 Sep 2026 and published as a CSV of ARKK daily closes. The closes are price only, adjusted for splits, with no distributions added back.
The last close of each year runs $20.16 in 2014, $20.46, $20.05, $37.08, $37.19, $50.05, then $124.49 in 2020. After that come $94.59 in 2021, $31.24 in 2022, $52.37, $56.77 and $76.92 in 2025, and $91.70 on 24 Sep 2026.
Eleven calendar years, one at a time
Year by year, from 2015 to 2025, the change in price was 1.49%, -2.00%, 84.94%, 0.30%, 34.58%, 148.73%, -24.02%, -66.97%, 67.64%, 8.40% and 35.49%. Seven of those eleven years were up by the closes, three were down, and 2018 was close to flat.
The spread between the best and worst year is 215.70 percentage points, from 148.73% in 2020 to -66.97% in 2022. A fund that can move that far in either direction in twelve months belongs in a different part of a portfolio from one that tracks the whole market.
In the 24,971-video corpus this site studies, 2 titles name Cathie and 2 name ARK Invest or ARKK. The most-watched, at 7,742,812 views, carries a price forecast for 2030 in its title. A forecast in a title is a claim about the future, not a record, and it is the record that is charted here.
When it fails
The first failure is buying the story at the top. A 148.73% rise in 2020 was followed by two down years that took most of it back. A theme that has already been bought by everyone has less room left, and the price can fall for years while the theme itself stays intact.
The second is sizing it like an index fund. A holding that fell 81.07% from its high does something very different to an account at 5% of the portfolio than at 50%. Concentrated funds belong in small positions for most people, if at all.
A third is judging the manager by one period. Pick 2020 and she looks unbeatable; pick 2022 and she looks reckless. Neither year alone is evidence of skill or of its absence, and the calendar decides which story gets told.
A fourth is reading the fund’s buying as a signal. ARK’s published holdings file makes its changes visible, and anyone can copy them. By the time the file is published the trade is done, and the fund’s reasons and time horizon are not in the file.
And a fifth is ignoring the fee drag in flat years. At 0.75% a year, a fund that goes nowhere for several years still costs its holders money in each of them. The expense ratio page shows how that compounds.

Growth investing is the wider approach ARKK takes to an extreme. Drawdown explains how to measure a fall like 2021 to 2022, and why recovering from it takes a larger percentage. And ETF investing covers how an exchange-traded fund like this one is bought and held.
Before buying a concentrated fund, look at its worst year, not its best one, and ask whether you would have held through it. With this one that means asking whether you would have stayed in after a two-thirds fall in a single calendar year.
