Base (Consolidation)
A base, or consolidation, is a period when a stock's price moves sideways within a narrow range instead of trending up or down. You'll see this on a price chart as a relatively flat, rectangular pattern—the stock bounces between a consistent high and low but doesn't break out in either direction. Traders watch for bases because they often precede big price moves; once a stock breaks above the top of its base, it can signal the start of an uptrend. Think of it like a spring getting compressed—the longer it stays squeezed, the more potential energy builds. For example, if TechCorp stock trades between $50 and $55 for three months, then suddenly jumps to $60, that sideways period was the base.
