How to assess diversification in a copy portfolio
A copy portfolio is diversified only to the extent that its risk sources differ. Several wallets can hold the same leveraged market exposure and lose together. Inspect leader behaviour, market concentration, direction and overlapping return history alongside the published capital weights.
Count risk sources rather than addresses
Three different leaders can all be long the same market. Their names and trade frequencies may differ while their dominant price risk is nearly identical. Adding another address can increase total exposure without adding a useful offset. Begin with each leader’s current markets and direction, then look at how those patterns change through history.
Likewise, several correlated crypto assets can respond together to market stress. Ten market rows do not prove ten independent bets. Label concentration in plain language so the portfolio remains understandable outside a chart.
Capital weights are not risk shares
A leader assigned a small capital weight can dominate risk if it uses much larger notional exposure or trades more volatile markets. Hypothetical example: half the capital follows an account using one-times exposure and half follows an account using five-times exposure. Equal capital weights produce substantially unequal gross exposure contributions.
Inspect both gross and net exposure. Opposing positions can reduce directional exposure while still generating fees, funding and basis risk. A low net number alone does not describe the cost or fragility of the combined book.
Correlation needs usable overlapping evidence
Return correlation asks how measured outcomes move together over a shared period. It depends on the sampling interval, account-return method and coverage. Two accounts with little overlapping history cannot support a confident diversification conclusion. A missing correlation should remain unknown rather than being treated as zero.
Historical correlation can also change. Leaders who looked different in quiet markets may react similarly during a sharp decline. Use correlation as one piece of evidence together with actual exposure and observed stressed periods.
Review updates and combined account risk
A portfolio version can change leaders or weights, which changes the diversification assessment. Revisit the combined book after an update and after a material leader behaviour change. Include other subscriptions and manual positions in the follower account. Diversification can reduce concentration, but it does not remove market loss, execution problems or correlated stress.
- Check shared markets and directional bias.
- Compare gross exposure contributions.
- Require adequate overlap for correlation.
- Review cash handling and portfolio versions.
