Often peak noise tends to lag the underlying trend that caused it.
Worse the trend is often already receding when noise picks up.

Although the numbers peaked in the autumn of 2015 the noise still continues.
This is important for investing – next time you find yourself pondering noisy news flow, ask yourself – what is the data saying? What is the underlying trend doing?
