They can still use social channels almost as a content aggregator to comment / share / repost content that is within their domain. They don't HAVE to be explicit about their plans. Would help build trust.
I REALLY hope they're baking comms into their strategy - Appreciate that the financial markets are heavily regulated when it comes to coms BUT this doesn't stop them from building up an authoritative presence in the space.
I still reckon this week has plenty of activity left in the market and we will see some big movement.
