Base (Consolidation)

A base, or consolidation, is when a stock's price moves sideways in a tight range for a period of time, rather than trending up or down. You'll see this on a price chart as a relatively flat, rectangular pattern. Traders watch for bases because they often precede big price moves—the stock is "gathering energy" before breaking out. It matters because spotting a base early can help you position before a potential rally. For example, if TechCorp stock bounces between $50 and $52 for three months, then suddenly jumps to $58, that sideways period was the base. Bases show that buyers and sellers are in balance, which can signal a shift is coming.
