NVDA: 1 week before earnings effect. Supply-demand imbalance.NVIDIA CorporationBATS:NVDAcitsvarParretto principle (20-80): small important things can have great influence in grand scheme of things. Some events have greater weight, than say 80-90% of daily events. Stocks move based on Supply-demand dynamics (disbalance etc), patterns or trends are just a feedback. The problem with using charts as a feedback for strength (or feedback for S-D strength) is that: (1) on a expensive market, with extended prices (with high supply too), (2) during important NVDA earnings, it's almost predictable how markets would sink, or at least be volatile. Demand stalls. Supply gets worried. Price down. //People are risk averse. Hence.. predictable.
