In all seriousness, I think this paragraph is extremely bearish:
This will be implemented gradually each day, increasing Initial margin requirements from normal levels starting September 28th to a rate that will be 35% higher by October 23rd. Maintenance margin requirements will increase in a similar manner between October 5th and October 30th. The new requirements will be implemented each day, after the market closes in New York, and will be effective the next trading day.
To me, it sounds like there will be daily margin calls of highly leveraged retail investors during the entire month of October. That can’t be bullish for stocks.
The more conspiracy-minded might see this as a way for “the deep state” to pull the plug on Trump’s stock market, but we all know that is just crazy talk.
