Correlation Concentrates Risk
How many positions do you have to hold before you are diversified?
The idea
Different tokens may fall together because they share liquidity, leverage, or narrative drivers.
In the real world
Five altcoin positions behave like one large crypto-beta position in a selloff.
Going deeper
Diversification requires differing drivers, not differing names. Eight altcoins across four sectors can share liquidity conditions, leverage dynamics and the same underlying risk appetite, which means they are one position with eight tickers.
Correlations also rise under stress, which is exactly when diversification is supposed to help. Assets that behave independently in calm markets fall together in a liquidation cascade, because the marginal seller is a leveraged holder unwinding everything at once. Counting positions measures variety; asking what would have to be true for these to move differently measures diversification.
Where it stops applying
Genuinely uncorrelated assets exist but usually come from different asset classes entirely. Diversifying within one highly correlated market has real but limited benefit.
Why it matters
Holdings that move together are one position wearing several names.

Measure common exposure instead of counting ticker symbols.
Test yourself
A portfolio holds eight different altcoins across four sectors. In a sharp selloff they all fall roughly together. Why did the spread not help?
Show the answer
They share the drivers that matter under stress: the same liquidity, the same leverage unwinding, the same risk appetite. Diversification requires differing drivers, and counting names measures variety rather than independence.
