U.S. economy grew faster than expected this quarter

U.S. GDP expanded at a 3.3% annual rate in its third quarter — the fastest rate since 2014, outpacing the expected 3.2% rate.

Why it matters: This growth was mostly due to more business investment in inventories, not consumer spending. Some economists give partial credit to President Trump's tax reform plan, according to CNBC, which calls for a lower corporate rate of 20%.
