"Canadian energy giants Suncor Energy (NYSE: SU) and PetroCanada (NYSE: PCZ) announced their intention to merge; Suncor, a holding in our 'Wildcatters Portfolio' will be the surviving entity," says Elliott Gue.

In his The Energy Strategist, he explains, "The combined firm will be the fifth-largest energy company in North America and the largest in Canada." Here, he explains why the new stock remains a buy.

"The combined firm will have more financial flexibility than Suncor did on its own. Debt ratios will be healthier, and the combined firm will also be able to redirect certain planned capital expenditures to higher return potential projects.

If 'buy low, sell high' means anything, we should be buying stocks now with whatever cash we can find. Otherwise, the ship will sail without us. Of course, given the exact market bottom is not knowable until after the fact.

"Indeed, new purchases may not be perfectly timed, but we continue to believe that it will be better than not buying at all. And because our policy with our 2-for-1 portfolio is to buy something every month, at least one of our purchases over the next several months will be very close to perfectly timed.
