One of the top analysts on the housing sector said Wednesday that there is big upside for investors in homebuilder stocks because of the strength of the industry during the coronavirus recession.

Ivy Zelman, CEO of Zelman & Associates, told CNBC's "Halftime Report" that the recovery in housing has surpassed her expectations and left the stocks in the sector undervalued.

"The recovery that we've seen in May and now into June has been frankly remarkable," Zelman said.
