Oxy and ConocoPhillips will sport lower profit margins when oil prices are low. But both companies can still be free cash flow (FCF) positive at prices much lower than today's levels. Oxy's portfolio has a breakeven level below $50 per barrel, while ConocoPhillips is working toward being FCF positive at just $35 per barrel.

General Dynamics' stock stands out as a top pick thanks to its robust dividend profile. It currently offers a healthy yield of 1.86%, boasts a five-year annualized growth rate of around 5%, and maintains a fairly conservative 42.7% payout ratio.

These powerful dividend stocks, yielding between 4.8% and 7.9%, could generate massive returns in the next decade.
