Does Fibonacci listen to the news?

Friday's non farm payrolls were worse than expected causing a spike down in the USDCAD. But was the spike just a random reaction to the news or was response by traders planned to sell off the USDCAD so they they can buy it back after they lowered the price sufficiently to come in with some size? Look at the chart below;
 

Note that the spike down, after the news was released, was to the 78% Fibonacci line. Thereafter, buyers bought the dollar all the way back to 1.0034. So was it better to sell the USD on the news and scalp the trade or to wait a while and buy it back at the support?
