According to the most recent survey of the Middle Market Institute, the percentage of middle market companies seeking to invest extra cash is at an all-time high. 71% of the companies surveyed are seeking to invest extra cash in the second quarter of 2018. This is up 4% points from the comparable period in 2017 of 67%. This is a powerful driver of economic activity and leads to greater capital spending, hiring and acquisitions. Although interest rates are on the rise, all-time high market bullishness and optimism should continue to propel the economy through the end of 2018 and well into 2019.
