A Stock-Specific Run, Or A Market Move?
Over the same 6 trading days, the S&P 500 returned -0.4% including dividends, so the run is mostly Sirius XM’s own story rather than the market’s. Over the past three months the stock is up 12.8%, a window that includes the streak; over the other 57 sessions of that window it was down 8.0%.
Is The Business Keeping Up With The Stock?
On the fundamentals, revenue grew 0.5% over the last twelve months, against a median of 9.3% for S&P 500 Communication Services stocks; its operating margin is 22.4%, versus a median of 20.9%; and the stock trades at 12.5 times trailing earnings against a median of 16.8. The read is mixed: margins above the median and a multiple below the median on one side, revenue growth below the median on the other.
