Tech Five: Lending Club shares slide

Shares of Lending Club are trading lower Tuesday after receiving a subpoena from the Justice Department. Meanwhile, a move by Amazon is lowering investors' appetite for GrubHub.

Let's look at tech stocks to watch Tuesday:

Lending Club. The peer-to-peer lending service is facing scrutiny after its founder and CEO resigned following an investigation into improper loan sales. The revelation cost Lending Club a third of its market value.

GrubHub. Shares of the food delivery service slid Tuesday after Amazon revealed it would expand its own service to two major markets: Dallas and New York. The service is available through Amazon Prime.

Twitter. The social network is reportedly planning to no longer count photos or links among the 140-character limit for tweets. Right now, photos or links take up roughly 23 to 24 characters in a single tweet.

Alphabet. With the Google I/O developers conference expected to kick off Wednesday, the tech giant could reveal an Android user base topping 2 billion.

Amazon. The retailer is adding several new Alexa voice features to its Fire TV set-top box. Users will be able to launch apps or play specific content through voice commands.
