Will the stock market go level 3 Wednesday?

23. A former floor trader said he thinks algos are behind the

very orderly run for the exits. In early March all three indexes would drop by the nearly same percentage day after day, about 0.5% Algos drive prices to even numbers which are tied to options trading.

SPY close $560 on 3/10

I follow shipping. I was researching Henry Hudson and that period, 1570 to 1620 and had to learn a ton about shipping to understand Spain vs England vs France, routes to Cathay, piracy, arbitrage, all that. Dang little has changed in 400 years. Shipping is still the middle of the supply chains.

The plan is much more than tariffs -- million-dollar port fees, ship registry stuff, fleet building. What Trump wants to do can be done but it can't be done on Wednesday. You don't just order a fleet of ice breakers and LNG transport ships from Amazon Prime and have them show up in Greenland on Thursday. I lean toward those who believe that this will be a slower transition than the current hysteria conveys.

Trump will want something to start on Wednesday so I'm thinking it will be the least disruptive tariffs. Stuff that can be collected on and the shipments move and while other more critical supply chains have time to reconfigure. And it will be countries that he is mad at: French wine. Canadian food. Canola oil, Canadian soy, wheat and corn. Chinese EVs, solar panels, PPE.

ETA: This guy covers a lot. Too much perhaps but it is indexed and front loaded so the big developments are covered first:
