Declining volume and deteriorating market internals in the Nasdaq-100 suggest that buying enthusiasm is fading and participation is drying up, signaling a potential reversal.
Too little corroboration in the last 3 days to call a trend (1 article). Watching for it to gain traction.
Analysis drawing on Bulkowski's technical research notes that the most consequential Diamond Top formations tend to show peak volume near the pattern's highest high, followed by a steady decline in volume as the pattern matures. This volume deterioration is interpreted as evidence that buying conviction is exhausting itself even as prices remain elevated.
Volume is a measure of conviction behind price moves, and when prices hold near highs while volume contracts, it reflects a shrinking pool of buyers willing to absorb supply, a structural imbalance that historically increases the probability of sharp mean-reversion once support levels are tested.
"Bulkowski observed that the strongest Diamond Tops often exhibit peak volume near the pattern's highest high, followed by steadily declining volume as the formation matures. That volume signature suggests participation is drying up as buying enthusiasm fades. The current QQQ chart displays that very behavior."
