Shares of Yelp continue to slide after revealing its chief financial officer will step down this year.

Let's look at technology stocks to watch Tuesday:

Yelp. Shares of the online recommendations service are down in Tuesday trading after announcing CFO Rob Krolik will step down either in December or when a replacement is found, whichever happens first. During the fourth quarter, Yelp reported $153.7 million in revenue, beating estimates.

Fitbit. Shares of the fitness wearable maker slipped following a Monday decline of more than 8%. For the year, shares of Fitbit have plunged 52%. Last week, Fitbit introduced the Alta, a slimmer version of its fitness tracker aimed at female consumers.

Alphabet. Google CEO Sundar Pichai received 273,328 Class C shares of the company last week, valued at about $199 million. Pichai's overall stake in the company is now worth $650 million.

Facebook. Starting this week, users of photo app Instagram will be able to access and switch between multiple accounts. The feature will be included in the next app update for iOS and Android users.

Verizon. AOL CEO Tim Armstrong will reportedly take the lead in exploring a deal to acquire assets from Yahoo. Last week, Verizon CEO Lowell McAdam told CNBC the company was considering a bid.
