As a listed (and frequently strongly performing) company, HL should expect its shares to be over represented in some of the best performing funds it sells to clients and it will be held in funds operated by competitors (just as Pru, Lgen, Aviva will have holdings in each other].
I am not sure what message they are giving the market by removing LT for having too much HL stock. One could take an inference that HL is overvalued and hence LT is going to underperform....but that does not appear to be it. Would it not have been better to list out the funds owning HL stock (including trackers) and then set out policy that these investors have no inside access to HL and that the wealth fund listings consider concentration risk as a risk to future performance....the FMs will get the message that some overweight in a share like HL is OK but betting the house on a small number of stocks is not.
Being whiter than white could have unintended consequences- LT May now sell out of HL (if they do, then speculators will short the stock, just as they have Woodford holdings which all results in a much lower SP)
