Data suggests that 73% of the large-cap funds have 40-60% overlapping. Some overlap is a given in the large-cap world, but excessive overlap reduces all the benefits one can get from excess diversification, irrespective of whether the approach is active or passive.
When you invest in multiple funds from the same large-cap universe without realizing the consequences, there is a high chance of an overlap of a few stocks. And if these stocks perform negatively, all the funds in the portfolio will also deliver negative performance. The aim of diversification is to spread risk.

Hence, one should be mindful of the risk and accordingly diversify in their choices of funds and mitigate that risk whatever approach they take, either active or passive.
