Angle of Repose, from Jim Sogi

August 24, 2019 |

Friday's price action reminded me of the mountains where when the Orange-u-tan man twittered the market slid off 3 percent, rapidly at first at a vertical slope, and then as the day wore on, settling in at the angle of repose where no more loose debris slid off and the top of the sell off might have been at a lower angle than earlier in the day. Years ago Chair discussed vectors and some algos based on vectors that was promising, and this is somewhat similar. Better to stand in a place where further secondary avalanches or what is known as Hangfire doesn't threaten your position.

As I say in the mountains, as in the markets, you never know til you go.

A mountainside with steep cliffs and loose scree below or snow tends toward the angle of repose which is the angle after which the loose material will no longer slide down the face. A pile of sand will have a certain angle of repose where the sand castle stabilizes for a time. For snow, typically slopes angled over 50 degrees tend to slough off. 38 degrees is the optimum angle for avalanches. A steep cliff will often slide down to where debris has piled up, and stabilizes at the angle of repose. When setting up a camp one wants to be at a point far enough away from the slide path that the run out of a avalanche debris will not bury the camp. A rule of thumb is that if the top of the slope is 17 degrees up by line of sight from the spot one might be relatively safe.
