Is it smart to have both (UA) and (UAA) or should I just have one or the other?

It's important to consider your investment goals and risk tolerance when deciding whether to invest in both Under Armour (UA) and Under Armour C (UAA) or just one or the other.
Both UA and UAA offer exposure to the company's performance, but they differ in terms of their capital structure and voting rights. UA is the common stock, while UAA is the Class C stock. As such, UAA may offer some advantages in terms of voting rights and other financial metrics.
Ultimately, the decision to invest in both stocks or just one depends on your individual investment strategy and risk tolerance. It may be beneficial to consult with a financial advisor to determine the best course of action.
