Strong positive
When one moves up, the other tends to follow.
Apple Inc.
↗AAPL
Apple is among the largest companies in the world, with a broad portfolio of hardware and software products targeted at consumers and businesses. Apple's iPhone makes up a majority of the firm sales, and Apple's other products like Mac, iPad, and Watch are designed around the iPhone as the focal point of an expansive software ecosystem. Apple has progressively worked to add new applications, like streaming video, subscription bundles, and augmented reality. The firm designs its own software and semiconductors while working with subcontractors like Foxconn and TSMC to build its products and chips. Slightly less than half of Apple's sales come directly through its flagship stores, with a majority of sales coming indirectly through partnerships and distribution.

Robinhood Markets, Inc. Class A Common Stock
↗HOOD
Robinhood is a diversified financial services provider best known for its retail brokerage platform, which historically caters to a young, risk-seeking clientele that trades heavily on margin and in higher-risk asset classes like options, futures, cryptocurrencies, and more recently, in prediction markets. As those customers' financial needs have begun to mature, Robinhood has rolled out a suite of more conventional products, from retirement accounts to high-yield cash sweep accounts to nascent advisory services (Robinhood Strategies). With $322 billion in customer assets and 27 million active accounts at year-end 2025, the firm has emerged as a significant player in the large and quickly growing US brokerage market.
