While Uber’s business continues to post strong gains, three mutual-fund companies marked down their investments in the ride-hailing app by 15 percent, suggesting these investors are souring on the scandal-ridden company.

Uber’s gross bookings rose 17 percent in the second quarter, to $8.7 billion, and revenue more than doubled to $1.75 billion from the year-earlier period, according to a report in Axios, which said it got a look at the company’s books.

The number of trips increased 150 percent, including 90 percent in developed markets, and adjusted net loss fell 14 percent, to $645 million, according to the report.

Vanguard Group, Principal and Hartford Funds all marked down their shares, to $41.46, for the second quarter, Dow Jones reported.
