More evidence that the economy continued to chug along came this week when the Institute for Supply Management said its non-manufacturing index jumped 110 basis points from January to February, and reached 57.6%. For context, any rating above 50% means more businesses are expanding. The 57.6% rating was the highest since October 2015, and the expansion of 16 of the 18 sectors was the highest number since the middle of 2014.
