Equities have reacted more negatively to the headlines since this one here, and US futures have now erased gains on the day. S&P 500 futures are flat alongside Dow futures while Nasdaq futures are down 0.1%.
Just be reminded that it is a US holiday later today so that will make for an interesting session with lighter trading conditions.
