More sleeves does not automatically mean more diversification

What to remember
If three strategies all lose in the same moments, you do not own three independent sources of return. You own one crowded risk packaged three ways.
This is why a lower-return sleeve can still improve a portfolio if it behaves differently enough from the rest of the stack.
The trap is evaluating each sleeve in isolation, then mentally averaging the Sharpe ratios. Portfolios do not work that way. The interaction terms matter just as much as the standalone sleeve stats.
The multi-strategy scenarios make correlation concrete. You can compare a diversified stack, a crowded stack, and a barbell build without pretending they are all the same just because the standalone sleeves look respectable.
