The chief financial officer of LendingTree Inc., an online market for mortgages and other loans, profited more than $700,000 after exercising options and selling shares, according to a Nov. 21 Securities and Exchange Commission filing.

Gabe Dalporto exercised the option to purchase 3,325 shares at $33.59 per share for $111,687. Gabriel thensold 8,425 shares in the company at $97.58 per share for $822,112.

Dalporto joined LendingTree in April 2011 as chief marketing officer for the company and assumed the role of chief financial officer in June 2015.

The number of officers and directors of companies purchasing their own stock tumbled 44 percent in July from a year ago to 316, the lowest monthly total ever, according to data compiled by The Washington Service and Bloomberg that goes back to 1988. With 1,399 executives unloading stock, sellers outnumbered buyers at a rate that was exceeded only two other times.

The slowdown of executives purchasing their own stock may be a warning signal for investors. The reluctance to buy is a departure from February when insiders rushed to scoop up shares during a period of large selloff, according to Bloomberg.

LendingTree currently employs more than 360 people, split mostly between Charlotte and its California office. Of the total employees, 287 are based in North Carolina.

LendingTree will invest $47 million and double the employee base of its Charlotte headquarters over the next five years, creating 314 jobs during that time span, Charlotte Chamber and state commerce officials announced on Nov. 2.

LendingTree’s expansion plans include a new 136,812-square-foot, two-building headquarters campus in Charlotte that will accommodate technology experts and marketing and customer service representatives, along with other personnel.

Shares of LendingTree closed at $102.55 Monday, up 2.55 percent.
