The U.S. economy is growing at one of the fastest rates in the developed world right now, and unemployment hit a nearly 50-year low of 3.6 percent in April. Under normal circumstances, this should boost demand for domestic equities. Some investors, however, are hesitant to participate due to escalating trade tensions between the U.S. and China, among other factors. The latest fund flows report from Morningstar shows that investor appetite for equities has declined so far this year in favor of asset classes that are perceived to have less risk, including government and municipal bonds.
