How to read crypto sector rotation
What are crypto sectors and narratives?
Crypto rarely moves as a single asset. Coins cluster around shared stories — artificial intelligence, meme culture, base-layer blockchains, scaling networks, decentralized finance, tokenized real-world assets, games, physical infrastructure networks. Traders call these clusters narratives. When a narrative catches attention, capital and trading activity concentrate in its coins; when attention fades, it moves elsewhere. Grouping coins into a small set of understandable sectors makes these shifts visible instead of drowning them in hundreds of individual charts.
What is capital rotation?
Rotation is the movement of trading activity and performance leadership from one group of assets to another. In equities it describes money moving between defensive and cyclical industries; in crypto it is faster and louder. A typical sequence is Bitcoin first, then large caps, then smaller sectors such as memes or AI tokens. Rotation is not a law and does not repeat on a schedule, but tracking which sectors are gaining or losing relative strength shows where the market’s attention is right now.
How to read the rotation graph
The Relative Rotation Graph places every sector on two axes. The horizontal axis is relative strength against Bitcoin: to the right of 100 a sector has been stronger than BTC, to the left weaker. The vertical axis is momentum of that relative strength: above 100 it is accelerating, below it is slowing. This creates four quadrants. Leading sectors are strong and getting stronger. Weakening sectors are still strong but losing momentum. Lagging sectors are weak and getting weaker. Improving sectors are weak but recovering. Sectors usually rotate clockwise through the quadrants, and the tail behind each dot shows its path over the last several points. Press Play to watch the movement.
Why share of trading volume is the proxy for money
There is no public ledger of “money moving from memes to AI”. Every trade has a buyer and a seller, so money does not literally leave a sector. What can be measured honestly is where trading activity concentrates. The share of total altcoin volume that a sector captures, and its change in percentage points, shows where traders are spending their attention and capital. Market cap changes are mostly driven by price and say less about flows. That is why the map leads with share of volume and pairs it with returns and relative strength.
How sector indices are built
Each sector index is cap-weighted, but no single coin can exceed 25% of the sector. Without the cap a sector like memes would simply track Dogecoin and Layer 1 would track a couple of giants. Breadth — the percentage of coins in the sector that rose — tells whether a move is broad or carried by one coin. Leaders, laggards and contributions on each sector page show who actually moved the index.
Limitations
The map uses exchange candle data from connected venues, a curated but subjective taxonomy and an approximation of historical market cap (current supply). Short periods such as 24 hours are noisy, and a sector entering the Leading quadrant is an observation about the past, not a forecast. Nothing on this page is investment advice; use it as a map of where the market’s attention has been.
