The mirror of accumulation. After an uptrend, price stalls in a range while supply quietly meets each attempt to rally. The chart looks healthy to anyone watching only the trend, because no decline has happened yet.
Cues traditionally cited are rallies on falling volume, wyckoff-upthrusts above the range that fail, and increasingly weak responses to good news. Breadth measures like the advance-decline-line failing to confirm new index highs are the market-wide version of the same idea.
Same warning as accumulation: the label is usually applied after the break. Treat distribution as a hypothesis that must be paired with a level that invalidates it, not as a reason to short a trend that is still making higher highs.
