I haven't read anywhere what effects it has on Funds that lend them out. I think it would be nice if Fund shareholders knew what effect it causes to their holdings.
If someone is winning, then someone is losing.
What also would be good, is that Funds that do it are made known to the public. Or is it the the case that all funds do it.
I ,and I am sure a lot of other people would like to know the pluses and minuses to a Fund that lends out stocks to shorters.
