Wall Street institutions are undertaking an unprecedented review of their gun-related investments following the recent mass shooting in Florida.

Some of the world’s biggest banks and investment funds are considering reducing their ties with gun makers and firearms retailers in the wake of the massacre, which killed 17.

A senior source at a top fund manager told The Sunday Telegraph that there is “much more to come” from investors. One source said statements regarding ethical concerns and financial risks had already gone further than ever before.

A leading figure in determining how ethics rules are applied to Norway’s $1 trillion sovereign wealth fund said that it is highly likely that opposition politicians will press for restrictions on firearms investments.
