A breakout is when a stock pushes above a price level that has repeatedly stopped it before — old resistance, a consolidation ceiling, or a 52-week high. It matters because it means the supply that was capping the price has been absorbed.
At a well-watched resistance level, sellers queue up. If buyers absorb all of that supply and push through, two things happen: the sellers are gone, and everyone watching now sees strength. Old resistance frequently flips into new support.
The most expensive pattern in trading: price pokes above resistance, triggers everyone's buy orders, then collapses back below within a session or two — trapping the breakout buyers at the top.
