History will look kindly on how 2019 played out for Sirius XM Holdings ( SIRI ). The shares have yet to take out the 14-year highs they set in the springtime of last year, but it's another winning year for the resilient satellite-radio provider. Sirius XM closed last week at its 2019 peak, and the 27% dividend-adjusted gain will easily stretch its impressive streak of positive returns to 11 years in a row.
