Parabolas Are Scary, but They Can Endure

Parabolic moves scare me. We are having parabolic moves in stocks like National Oilwell Varco (NOV - commentary - Cramer's Take) and Southwestern (SWN - commentary - Cramer's Take) and Continental Resources (CLR - commentary - Cramer's Take).

But are parabolic moves ever deserved? Southwestern has been making big finds. Continental Resources had a gigantic oil hit this week. Much bigger; numbers can go higher. Petrobras' (PBR - commentary - Cramer's Take) voracious appetite for rigs gives NOV the earnings visibility through the next decade!

The moves are troubling. We know these stocks can't go up forever -- nothing can.

But let me reach back to the early days of the 1980s when we got the same issue: oil going up and finds galore. Anyone remember Dome Petroleum? The moves went on for doubles and doubles.

Of course, they then crashed. But not until both the commodity crashed and the finds stopped.

My conclusion: Neither curse is happening right now. So stick with the program.

Random musings: Apple (AAPL - commentary - Cramer's Take) and MasterCard (MA - commentary - Cramer's Take), the two tells of this market, are robust. That will give the green light to the funds that have held off buying this tape. Remember, that's what leadership does.

At the time of publication, Cramer was long National Oilwell Varco.
