ARK Invest, the investment firm led by Cathie Wood, spent about $77 million buying U.S.-listed crypto-related equities in June, even as Bitcoin went through one of its weakest monthly periods in four years. Based on ARK’s daily trading disclosures, the firm added roughly $44 million of Coinbase, $25.25 million of Circle, and $8.2 million of Bullish during the month.
The logic behind these trades is not new. Wood and other institutional investors have long argued that publicly traded crypto companies provide a regulated way to gain exposure to the sector without directly holding Bitcoin. In theory, investors can participate in the upside of the crypto cycle through equities while avoiding the operational burden of direct token ownership.
However, market data analyzed through July 2 suggests that this route comes with a substantial trade-off. If investors focus only on price swings, crypto equities can look like leveraged versions of Bitcoin. But once volatility is compared with correlation, a different reality emerges: many of these stocks do not track BTC tightly enough to act as clean substitutes, and their performance is often driven by company-specific fundamentals and balance-sheet dynamics rather than by the coin itself.
Volatility is high across the sector, but Bitcoin linkage is uneven
Among nine U.S.-listed crypto companies, 30-day annualized realized volatility ranged from 68% to 90%, nearly double Bitcoin’s 37.6% over the same period. On a 90-day basis, Circle’s volatility reached 103.6%, while Bitcoin stood at just 37.8%. Drawdowns tell a similar story. Circle fell 51.4% from its high, MSTR dropped 48.6%, and Bullish declined 43.6%. By comparison, Bitcoin was down 36.4% from its January high near $97,000.
That gap matters because investors often assume that crypto equities provide a more manageable version of crypto exposure. In reality, the data shows that many of these names deliver more severe swings than Bitcoin itself, even before accounting for the additional risks embedded in public-company structures.
Correlation data makes the distinction even clearer. Over the past 90 trading days, Circle, Robinhood, and Bullish posted correlation coefficients of only 0.55 to 0.58 versus Bitcoin. In practical terms, BTC price action explains only around one-third of the movement in those stocks, with the rest attributable to company-level factors such as earnings releases, competitive developments, capital raises, share dilution, and changes in strategic direction.
That means investors using equities to “play crypto” may end up with partial coin exposure plus a full set of equity risks. The stocks may carry the branding of the digital asset industry, but they do not all provide the same economic sensitivity to Bitcoin.
MSTR is still the clearest Bitcoin proxy, but the risks are different from spot BTC
Across the group, MSTR remains the closest substitute for direct Bitcoin exposure. With a beta of 1.59 and a correlation of 0.85 to BTC, it behaves like a leveraged equity wrapper around the asset. That structure can magnify upside during strong markets, but it also deepens losses during drawdowns. In the latest decline, MSTR’s year-to-date drop and peak-to-trough retreat both exceeded Bitcoin’s own losses.
Yet even MSTR introduces risks that spot BTC holders do not face. Shareholders are exposed not just to the underlying coin, but also to capital markets access, financing conditions, valuation compression, and the company’s ability to maintain a premium in public markets.
Coinbase offers stronger crypto linkage, while Circle and Robinhood show how business mix changes the picture
Coinbase looks like the most balanced name in the sector. Its year-to-date decline of 26.8% is slightly smaller than Bitcoin’s, and its beta of 1.26 with a correlation of 0.75 makes it one of the most BTC-sensitive equities in the group, second only to MSTR. Even so, Coinbase’s volatility remains close to twice Bitcoin’s, and the stock is still down 60.6% from its record high of $419.78 reached in July 2025. That illustrates a central point: even when a company is deeply tied to crypto activity, equity valuation risk can be much harsher than the underlying asset’s own pullback.
Circle represents a different kind of exposure altogether. It has the lowest correlation to Bitcoin in the group and the highest 90-day volatility. On June 30, the launch of the Open USD stablecoin — backed by more than 140 companies including Coinbase, Stripe, Visa, Mastercard, and BlackRock — triggered a 17.5% one-day drop in CRCL. The selloff had little to do with Bitcoin and everything to do with competitive pressure in the stablecoin market. Circle therefore looks less like a Bitcoin-linked trade and more like a payments and stablecoin company facing sector-specific rivalry.
Robinhood offers the opposite example. The stock was down just 0.3% year to date, with a maximum drawdown of only 8.5%. Crypto is only one segment of Robinhood’s broader platform spanning equities, options, and derivatives brokerage. That business diversification reduces its sensitivity to crypto market weakness. But it also limits the stock’s ability to fully participate in crypto-led upside during bull markets.
Mining stocks have diverged as AI and compute become more important than Bitcoin
Crypto miners have produced some of the most unusual performance in the group. Bitcoin was down 29.5% year to date, yet RIOT rose 74.5%, MARA gained 38.1%, and CleanSpark advanced 24.7%. On a daily basis, these names still react to BTC moves and generally show betas above 1. But their full-year return profiles are no longer being determined primarily by mining economics.
The main reason is strategic repositioning. A growing number of miners are turning into AI and high-performance computing infrastructure providers, signing multi-billion-dollar compute leasing deals and reducing the role of treasury Bitcoin in their valuation. As a result, their market performance has become increasingly tied to AI hosting and data-center narratives rather than purely to crypto prices.
This shift helps explain why mining stocks can still wear the label of “crypto equities” while delivering returns that are partially decoupled from Bitcoin itself. For investors, that makes them less useful as direct BTC proxies and more akin to hybrid infrastructure bets.
Strategy highlights the extra constraints that come with equity structures
The distinction between holding Bitcoin and holding a Bitcoin-heavy public company is especially clear in the case of Strategy. At the end of June, the company’s mNAV ratio fell below 1 for the first time. That metric compares the company’s total market valuation with the value of its net assets. When mNAV drops below 1, the market is effectively valuing the company at less than the worth of its cash and Bitcoin holdings.
As of the company’s June 22 disclosure, Strategy held 847,363 BTC. On the day mNAV slipped below 1, that stash was worth about $50 billion. Historically, the company’s premium valuation allowed it to issue common stock and preferred shares, raise capital, buy more Bitcoin, and increase BTC exposure per share. But once mNAV falls below 1, that same financing engine starts to work in reverse: issuing new equity to buy Bitcoin can amount to selling existing BTC exposure at a discount, eroding shareholder value.
By late June, Strategy’s market capitalization had dropped to $29.54 billion, less than half of its peak above $71 billion in 2024, while all four classes of preferred stock fell to record lows. On June 29, the company responded with a stock buyback plan of up to $1.25 billion and also authorized the sale of Bitcoin to support liquidity for preferred dividends and debt interest. Weeks earlier, on June 1, it had already sold 32 BTC, its first Bitcoin sale since 2022. The stock jumped 12.6% on the announcement, ending an eight-session losing streak. Still, the episode underlined a key point: public companies must manage liquidity, liabilities, and shareholder structure in a way spot Bitcoin holders do not.
ARK’s basket trade is really a bet on very different business models
That backdrop helps explain ARK’s buying activity during the late-June selloff. On June 25, as crypto equities broadly declined, Wood’s funds bought $3.27 million of Robinhood and added to Coinbase, Circle, and Bullish at the same time. Wood continues to argue that Bitcoin could eventually reach the million-dollar range, making current valuations appear attractive after the sector’s deep pullback from 2025 highs.
But the data suggests ARK is not simply buying a basket of interchangeable Bitcoin proxies. It is taking positions in companies with very different operating models and very different kinds of crypto exposure. Strategy is effectively leveraged BTC plus dilution and balance-sheet risk. Circle is a stablecoin and payments company caught in a market-share battle. Robinhood is a diversified brokerage where crypto remains only one business line.
Each stock may have its own investment case. Coinbase has outperformed Bitcoin on a year-to-date basis. Robinhood has largely held its starting level for the year. Mining stocks have led returns across much of the group. Even so, the central question remains the same: are crypto equities actually less risky than direct token ownership?
Based on the figures across the nine listed companies, the answer is not obvious. In many cases, the stocks either amplify Bitcoin’s volatility or layer on operating and capital-structure risks that have little to do with BTC price action. The strongest-performing “crypto stocks” this year have often been driven by independent growth engines such as AI compute, brokerage traffic, or payment products, with Bitcoin playing only a secondary role.
