Moody's Investors Service downgraded the U.K. outlook from "stable" to "negative." The referendum result, it said, "will herald a prolonged period of uncertainty for the UK, with negative implications for the country's medium-term growth outlook."
The news source is providing negative feedback as well. It is true that there is period of uncertainty for the UK. However, it may not result with negative implications. The investors are still getting into agreements as pound plunge has resulted in reduced deal value.
