Alphabet Inc. Class C Capital Stock
↗GOOG
Alphabet is a holding company that wholly owns internet giant Google. The California-based company derives slightly less than 90% of its revenue from Google services, the vast majority of which is advertising sales. Alongside online ads, Google services houses sales stemming from Google's subscription services (YouTube TV and YouTube Music, among others), platforms (sales and in-app purchases on Play Store), and devices (Chromebooks, Pixel smartphones, and smart home products such as Chromecast). Google's cloud computing platform accounts for roughly 10% of Alphabet's revenue. The firm's investments in up-and-coming technologies such as self-driving cars (Waymo), health (Verily), and internet access (Google Fiber) make up the rest.

↗RKT
Rocket Companies is a financial services company that was originally founded as Rock Financial in 1985 and is currently based in Detroit. Rocket Companies offers a wide array of services and products but is best known for its Rocket Mortgage business. The company's mortgage lending operations are split between its direct-to-consumer lending, which sees borrowers accessing the company's lending arm directly through either its mobile app or website, and its partner network where mortgage brokers and other firms use Rocket's origination process to offer loans to their customers. The company has rapidly gained market share in recent years and will also be the largest mortgage servicer in the US following its acquisition of the Mr. Cooper Group.
