Short Term:
Momentum dying
1) RSI divergence - As another user noted, RSI has been declining since September 1 high (88) to September 23 higher-high (76).
2) OBV - On-balance-volume is currently testing the $460-470 support, if we break thru, next line of support is $420. Hoping for a strong gap down tomorrow AM.
Stepping back, a fixed range volume profile shows next high volume nodule to be around $275-300, and going back to February 3 which marks the date when volume first started pumping in anticipation of the pandemic threat, the major point of control is $120. Technical analysis aside, 'hope' for a vaccine which will heavily bite into Zoom's thesis (stay at home)is ramping up. Dr. Anthony Fauci told Congress yesterday (ZM top) that there’s “growing optimism” that scientists will find one or more safe and effective vaccines by the end of the year or early 2021. I imagine this played a significant role in the reversal on the lower time frame charts yesterday, and sharp continuation of that reversal today.
