This might sound like an oversimplification, but Jim Cramer saw a lot of asymmetrical selling back in January, especially when it came to the wacky nature of oil.

Could this pattern permeate February as well, or will there be a new positive foundation to work from going forward?

One would think the asymmetrical disease has been cured considering that Monday closed with a nice rally. However, to fully understand what will happen going forward, Cramer thinks investors need to look back at what occurred for January.

"When the news is bad, the sellers are much more powerful than the buyers, and when the news is good the buyers just aren't paying up anymore," said the "Mad Money" host.

Oil was on the rise again on Monday, and the big question is, will it make a U- or V-shaped rally?

"I have to tell you I think the U camp makes more sense,even as we saw another dramatic spike in the price of crude today," said Cramer.

Every time oil spikes, Cramer hears speculation that there is a beginning of a V-shaped rally for oil. But Cramer noticed something else that wasn't talked about in the news.

Last week Chevron froze its buyback, and Exxon Mobil cut its buyback in half on Monday. If oil were really done going down, they wouldn't have done this. There would have been an increase instead.

"I see these spikes as a chance to lighten up. I'm with Chevron and Exxon. If they're freezing or cutting their buybacks, I want to wait to see what happens."

That doesn't mean that oil prices go back up, either. Cramer thinks it will come back but will take its time getting there.

If there is one thing that Cramer learned from watching the Super Bowl, it is that 2015 is the year of the connected car.

Cramer sees that these car infotainment systems have gone from luxury accessories to near necessities this year. He is willing to bet that in five to 10 years from now every new car will have one.

This explains how a stock such as Harman International (HAR) rallied 26 percent last week, amid an ugly market. Harman is the leading provider of automobile infotainment systems.

"I still think the stock is worth buying at these levels, although obviously I'd like it even more if gets taken down by the next inevitable marketwide pullback," said the "Mad Money" host.

So, keep this one in your back pocket for the next down day, because Cramer thinks Harman is at the epicenter of the biggest tech theme of the year. It's not just involved with connectivity to cars, it is connectivity.
