As a measure of similarity, one can calculate the overlap between two funds. The overlap between fund \(A\) and fund \(B\) will be calculated as: \[S_{AB} = \sum_{i} \sqrt{w_{A, i} \cdot w_{B, i}}\] Here, \(w_{A, i}\) is the weight of stock \(i\) in fund \(A\). This metric has the property that it is equal to \(1\) if the two funds are identical and \(0\) if ...
