Sirius XM Stock Is Up 53% in 2026: Take Profits, or Buy More?

Sirius XM’s stock has jumped 53% year to date in 2026, trading at $29.63 on Tuesday afternoon, up 0.9% on the session and near its 52-week high of $32.37. The rally is notable because the communication services sector ETF XLC is down 2% for the year, while the broad S&P 500 ETF SPY is up 11%, meaning Sirius XM has outperformed both benchmarks. The move is described as a “rerating” driven by improving cash-flow durability. In its July 30 Q2 report, Sirius XM posted $593 million in free cash flow (+48% YoY) on $2.16 billion revenue, and raised full-year 2026 guidance.
