Tariffs kick into affect tomorrow. Will the markets tmmr be up or down as a result?

I know today the markets are churned, rising and falling. But I’ve heard a lot of people say tmmr is the real “D-day” because of the fact the tariffs actually start tmmr. However it could also be the end of the tariff fall and a start of a recovery as the market already seem to be recovering slightly and today was not as bad as many predicted. So based on what we’ve seen so far do we think tmmr will finally be a Green Day or be the D day? Basically, is this priced in?
