Weight of the evidence has been suggesting flat/lower stock prices short- to medium-term, though that's starting to turn more neutral as stocks pull back; still suggesting higher prices long-term
Active Studies show a heavy positive skew over the medium- to long-term; breadth thrusts and recoveries have an almost unblemished record at preceding higher prices over a 6-12 month time frame
Signs of extremely skewed preference for tech stocks nearing exhaustion, especially relative to industrials and financials (here and here)
Indicators and studies for other markets are mixed with no strong conclusion
