Bullish on $NXF: oil-producer outperformance — benefits most from high oil prices and producer tilt.
NXF is winning the energy producers covered-call comparison, because rising high oil prices have benefited oil and gas producers more than pipeline-heavy strategies while NXF uses a slightly lower covered-call schedule.
In the energy category, NXF is shown as the top total-return performer and it makes sense because NXF is limited to oil and gas producers (no pipeline exposure). The covered-call setup is also described as slightly less overwriting than EMAC, which helps explain why NXF edges out close competitors in this window.
