1. I measured the distance off the Ichimoku Cloud, just before markets crashed in 2000 & 2008. We are definitely way too above the cloud support right now.
2. Assessing the data after 1994, the JMA2 moving average is currently in the longest uptrend streak ever, which has been running for 729 days. The uptrend is noted by the white line on the candles, and black line is the downtrend.
3. RSI on a monthly chart has faithfully indicated prior to the previous 2 market crashes.
4. Jurik Research's JU_VEL shows the momentum. It is at the highest reading ever since 1994. Momentum sooner or later slows down before gaining again.
There is also a hidden 5th reason behind those dividend indicators. The volume is dropping but the momentum is gaining which suggests an overly optimistic and euphoric market.
