Rocket Companies, Inc. (RKT) shares are taking a breather Monday after an explosive Friday session that saw the stock jump more than 10%. The catalyst? President Trump unveiled plans to buy mortgage bonds, potentially making homeownership more accessible and affordable for Americans.

The big question now is whether this rally has legs or if it's just another head fake. That's exactly why Rocket Companies earned our Stock of the Day spotlight.

Here's what happened on Friday: Rocket broke out.

In trading terms, a breakout happens when a stock pushes through a resistance level. Think of resistance as a ceiling where sellers congregate, a price point where enough people want to unload shares that the stock typically stalls out and reverses. It's like a crowded exit that nobody can quite get through.

For Rocket, that ceiling sat around $21.65. Back in September, the stock hit this level, then promptly turned around and headed south.

When a breakout happens, it signals something important: the sellers who created that resistance have either exhausted their supply or changed their minds and canceled their sell orders. And here's where it gets interesting.

With those sellers out of the way, buyers now have to bid higher to convince anyone to part with their shares. It's basic supply and demand, but it can create a powerful upward momentum.

Sometimes after a breakout, you'll see a small pullback or consolidation period. This is when technical traders get really interested, watching to see if that old resistance level flips and becomes support. If it does, it often sets the stage for another leg higher.

Rocket has shown this pattern before at the $13.25 and $15.65 levels, as the chart demonstrates.

Why does resistance become support? It's actually kind of fascinating from a behavioral finance perspective. Imagine you sold your shares at resistance, feeling smart about locking in gains. Then the stock breaks out without you. Suddenly you're filled with regret, kicking yourself for selling too early.

Many of these regretful sellers make a pact with themselves: if the stock comes back down to where I sold it, I'm buying back in. When Rocket pulled back to those former resistance zones, these traders stepped in with buy orders, creating support exactly where resistance used to be.

If the stock dips on profit-taking over the next few sessions, all eyes will be on that $21.65 level. If buyers show up there and defend it, technical traders will view that as confirmation that this breakout is the real deal and position for a sustained move higher.
