We've come up with some additional boundaries for the Market Blackhole effect.

Each of the percent changes are relative to some maximum, i.e. 52 Week High or an All Time High value.

Just a few computations for a theory we've been working on.

Entry in to the System of Investment Decay - The pull of the Economic Singularity is first noticed.

-1 + √20 / 21 ≈ -2.41%

Zeroth Investment Dark Moment - Economic Singularity locks on to the investment.

-1 + ⁴√1 / 2 ≈ -15.91%

First Investment Dark Moment - Direct escape from the Economic Singularity is near impossible.

-1 + √2 / 3 ≈ -18.35%

Second Investment Dark Moment - Diverted escape from the Economic Singularity is near impossible.

-1 + ((-1 + √17) / 4) ≈ -21.92%
