1987

First up here is a (slightly butchered) chart of the SP500 that I found on the internet. The bright red marks are my additions.

Next I'm going to show a bit of planetary phenomena from that time period.

First up is Saturn and Uranus on the same chart. What's notable to me is that both planets made lows in March and April, then moved up to highs in late July and early September before turning South again... correlating nicely with final run up in the SP500 from April/May to late August.

Next is Mars and Jupiter. Mars made it's high in May and then trended down for the rest of the year. Jupiter was in an overall uptrend but made a short term reversal that timed almost exactly with the August high and the secondary low in early December.

Mercury and Venus next. Mercury was the last to top and the first to bottom on the 1st of August and 16th of October respectively.

The 16th of October was a Friday and the "Black Monday" crash came one trading day later on Monday the 19th... Almost perfect!

Lastly the Moon. The moon orbits too fast to have a consistent trend for the entire course of a bear market but it did trend down during the fastest part of the crash from it's maximum North on the 13th of October. Many of it's max/min and zero points during that year also timed other major points on the price chart including the August high and October low (with a 2 day allowance).

So... During the 1987 crash every single planet from the Moon all the way out to Uranus trended down.

Does anyone have a coincidence theory for that?
