@solon, you have become a fine acolyte of the Great Thorstach.

Few numbers factor out into such pleasing proportions. 2800 = 10 x 10 x 7 x 4.

Or, 7 x (5 x 5) x (2x2x2x2). Meaning 7

^{1} x 5

^{2} x 2

^{4}. The exponents rise as the bases sink. The rising exponents represent the power of the rising market. But due to the declining base, further increases are impossible. The next base is obviously 1. And 1 raised to any exponent is 1, hence the series can no longer increase. The market will shortly collapse to a dense and tiny dot.

However you write it, the market gods clearly would not create a universe where the market rises past such a lovely stopping point.

Mathematically, top is in!
