In case you could not decipher the trend line angles, here there are in order (degrees).
5 deg
21 (4.2x previous)
39 (1.86x previous, 7.8x first)
32 (0.82x previous, 6.4x first)
44 (1.38x previous, 8.8x first)
65 (1.48x previous, 13x first)
74 (1.14x previous, 14.8x first)
83 (1.12x previous, 16.6x first)
Right now we are seeing average gains in the stock market that are 16.6x more per year (month) than what they where before the 1990's.
If we accelerate even more to like 1.08x over the next year, then the angle of the line would be 90deg (straight up) at this time scale.
If we stay at this pace (slope), then we could be at 4200 by mid-March, which would be another 14% in 3 months. That is more than some decades have seen in the stock market.
