Zillow Group's stock plummeted 5.27% in post-market trading on Tuesday, following the release of its fourth-quarter financial results and a negative analyst action.

The online real estate marketplace reported Q4 revenue of $654 million, net income of $3 million, and adjusted EBITDA of $149 million. While earnings per share of $0.39 met analyst estimates and sales exceeded expectations, Wells Fargo cut its price target on the stock to $61 from $73, maintaining an Equal-Weight rating.

The combination of the earnings release and the reduced target price likely drove the after-hours sell-off.
