Investor confidence in auditors and in capital markets in general fell in 2018, according to the annual poll by the Center for Audit Quality.

In an August survey of some 1,100 “Main Street” or average investors, 81 percent said they have confidence in public company auditors to act as protectors of investor interests, down from 84 percent in 2017. The hit to confidence in capital markets broadly was bigger, down 11 percentage points from 85 percent in 2017 to 74 percent in the late summer 2018 poll.
