A common baseline made relative paths comparable. Sleeve weights and the rest of the portfolio were still needed to establish contributions to the whole book.

Rebasing

Rebasing / Kuweka upya msingi
Rebasing divided each sleeve by its own starting observation and put both on a common scale. It did not equalise portfolio weights.

Source: the Ghost tracker for the closing date. Each sleeve was divided by its own exact first observation in this window and rebased to a shared starting point. The comparison established neither a trade, a causal explanation nor whole-book attribution.

Source and method

Source: After the Bell. Position shows the share of prior observations strictly below the close, not the size of the difference. Both measures and both displayed dates used the same complete cohort. Both displayed dates were excluded when a prior comparison was available. Ties counted in the denominator but not as lower observations. This held sample was not the full available archive.
