Tracking Stock

A Tracking Stock (also known as a 'letter stock') is a special class of common stock issued by a parent company. Its unique feature is that its market value is intended to track the performance of a specific business segment or subsidiary within the larger corporation. Think of a big, diversified company—let's call it “MegaCorp”—that owns both a steady, old-school manufacturing division and a flashy, high-growth software division. Instead of selling off the software unit, MegaCorp could issue a tracking stock for it. This allows investors to buy shares that are supposed to rise and fall with the software division's fortunes, all while the division remains legally part of MegaCorp. However, and this is the crucial part, shareholders of a tracking stock are still legally shareholders of the parent company, MegaCorp. They do not have a direct claim on the assets or cash flows of the specific division they are “tracking,” which creates some interesting and often problematic dynamics for investors.

Why Would a Company Issue a Tracking Stock?

Corporate managers don't create these complex securities for fun. Tracking stocks are tools designed to solve specific problems or unlock perceived value. The main motivations usually fall into a few key categories:

A Value Investing Take on Tracking Stocks

Value investors, who view buying a stock as buying a piece of a business, are deeply skeptical of tracking stocks. Legendary investor Warren Buffett has famously called them “an abomination,” arguing that they obscure accountability and create messy conflicts of interest. The core problem from a value perspective is the violation of a clear governance structure. As an owner, you want management's fiduciary duty to be clear and undivided: to act in the best interests of you, the shareholder. With a tracking stock, management's duty is split. Whose interests come first when a decision benefits the parent company but hurts the tracked division? The answer is almost always the parent company. Furthermore, the lack of a direct claim on assets and the absence of voting rights mean you aren't truly an owner in the way a value investor understands the term. You are holding a derivative-like contract whose value depends not only on the performance of a business unit but also on the whims and integrity of the parent company's board. For these reasons, most value investors steer clear. While the idea of isolating a great business sounds appealing, the structural flaws are often too great to overcome. A full, clean spin-off, where the division becomes a truly independent company with its own assets, board, and shareholder base, is a far superior and more investor-friendly structure.
