No reading of shorts ‘facts ’was never my strong part. If you are correct it means that one fund had to increase Lightwave by 20% (such a small portion in the weight) so all other sticks in that fund have increased with 20% aswell?? Proof of shit argument shorts this is what this index fund says: “We use the change in the portfolio allocation because this is the most meaningful metric. Changes can be due to trades or changes in share prices.” So apparently they do trades…..
