Still grow and grow

Here they say, markets have nowhere else to grow, already growing exponentially, weekly charts going wild, the bubble is inflated, etc..
Let's take a look at the weekly chart of the SP-500 index.. From here it can be seen, what else to grow and grow, given that the two previous growth swings were about 5,5 cells on the graph. Why should the third swing be shorter?? The logic is incomprehensible. So this is still a graph with a simple scale. (not logarithmic), where is the growth from 700 to 1000 far from the same as growth from 1000 to 1300 — in the first case, it is growth by 43%, and in the second on 30%. So this method of boxes on a chart with a simple scale on the Y-axis is still quite gentle for those who believe in an overbought market. — I didn’t scare you with a graph with a logarithmic scale :)
