Grayscale: Bitcoin Explains Half of Crypto Sector Return Differences

Grayscale says bitcoin explained roughly half the variation in sector returns over three years, leaving the other half open to asset selection as digital-asset sectors grow less correlated. The firm based the finding on its FTSE Grayscale Crypto Sectors indexes, which group tokens by function and use case, in an analysis of crypto investment risk published with data through Nov. 4.

The numbers behind the diversification argument are stark. Among the 10 largest non-stablecoin assets, six different cryptocurrencies led quarterly performance over the past two years — and bitcoin topped none of those quarters. Common market forces still matter, the authors noted, but they no longer dictate every sector's move.

Why do business models change token selection?

Grayscale's earnings-based valuation framework treats tokens like operating businesses. It examines fees generated by trading, lending and other applications, then weighs them against operating costs and distributions.

Several mechanisms can erode or support that revenue picture:

• Buybacks repurchase tokens from the market.
• Staking rewards compensate holders who commit assets to secure a network or protocol.
• New issuance creates tokens.
• Unlocks release previously restricted holdings.

Issuance and unlocks both expand circulating supply, and both can offset the benefits of buybacks and staking rewards. That supply-and-distribution arithmetic gives analysts a reason to treat tokens as distinct bets rather than one undifferentiated crypto trade.

Tokenized equities sharpen the point. In July, Grayscale identified Ethereum, Solana, BNB Chain, Avalanche and Canton Network — a public blockchain built for regulated markets — as potential beneficiaries of equity tokenization. The analysis distinguished third-party wrappers, tokens representing claims on shares held through a separate entity, from issuer-sponsored shares issued directly on a blockchain. Those two models, and the regulated securities infrastructure around them, could favor different networks.

The sector research extends a broader Grayscale argument. In September, the firm's Pandl contended that digital assets could diversify crowded equity exposure without replacing stocks as a core holding. The new findings answer a narrower question: how exposures differ within crypto itself.

Does lower volatility mean lower risk?

Not by itself. Bitcoin's annualized realized volatility, a measure of historical price swings, ran in the mid-40% range as of Oct. 31, down from triple-digit levels in earlier cycles, according to Grayscale. Extreme moves and momentum still define the asset class, with gains clustering and reversals turning sharp.

Schwab's work on crypto portfolio allocations adds a qualification: even small bitcoin or ether positions can significantly affect overall portfolio performance. Its framework weighs expected returns, volatility and correlations — or, alternatively, a risk budget, meaning the share of total portfolio volatility allocated to a single holding. Different price behavior across tokens does not guarantee protection during broad declines.

Within crypto, Grayscale separates two levers. Diversification governs the spread across holdings; position sizing governs the capital committed to each. The firm also flags a caveat on its own backtests: historical portfolio results reflected bitcoin's strong realized performance during the study period and shouldn't be read solely as forecasts.

The practical takeaway for allocators is a shift in workload — from deciding whether to hold crypto to choosing which sectors, tokens and supply schedules to hold. As tokenization pilots and sector indexes mature, expect selection frameworks like Grayscale's to anchor how institutions size positions going forward.
