Tracking stock or targeted stock are specialized equity offerings issued by a company that is based on the operations of a wholly owned subsidiary of a diversified firm. Therefore, the tracking stock will be traded at a price related to the operations of the specific division of the company being "tracked". Tracking stock typically has limited or no voting rights. Often, the reason for doing so is to separate a high-growth division from a larger parent company. The parent company and its shareholders remain in control of the subsidiary's or unit's operations.
During the dot-com bubble, some companies that predated the bubble identified their Internet operations as high-growth divisions that would benefit from a tracking stock. The best-known example is The Walt Disney Company, which issued a tracking stock for go.com. At around the same time the bubble ended, Disney retired the tracking stock. AT&T (AWE) and Sprint Corporation (PCS) also established tracking stocks for their cellular telephone operations, but neither of these tracking stocks is still outstanding.
Liberty Media (NASDAQ: FWONA and FWONK and OTCQB: FWONB after January 23, 2017 symbol changes from LMCA, LMCB, and LMCK) had tracking stocks for Qurate Retail Group (NASDAQ: QRTEA and QRTEB after March 18, 2018 symbol changes from QVCA and QVCB), Liberty Capital—formerly LCAPA and LCAPB on Nasdaq, Liberty Starz—formerly LSTZA and LSTZB on Nasdaq, and Liberty Entertainment—formerly LMDIA and LMDIB on Nasdaq, at various times since going public. However, on September 25, 2011, Liberty Capital and Liberty Starz could no longer be traded, leaving only Liberty Media and Liberty Interactive as separate companies. Therefore, no major U.S. companies had tracking stocks until August 9, 2012, when Liberty Interactive issued tracking stock for itself using the symbols LINTA and LINTB and Liberty Ventures—formetly LVNTA and LVNTB on the Nasdaq. Currently, Liberty Media has tracking stocks for Liberty Braves Group (NASDAQ: BATRA and BATRK and OTCQB: BATRB), Liberty Formula One Group (first three symbols), and Liberty Sirius Group (NASDAQ: LSXMA, LSXMB, and LSXMK).
Among other examples, in 1999 Quantum Corp. issued tracking stock in two subsidiaries: its DLT and Storage Systems Group (DSS) and its Hard Disk Drive Group (HDD). Two years later, in 2001, Quantum sold the Hard Disk Drive business to Maxtor and redeemed the HDD tracking stock.
