No, a significant number of market players are betting that this is like 2018-like short-term correction, i.e. Trump will drop the tariffs to a lower number after the negotiations ended. The US society cannot withstand such high tariffs since reindustrialisation has barely started. The optimistic people will be betting that the future presidents (8 or 16 years later) may not even follow through completely Trump's policies (only partial reindustrialisation).
Entertainment time:
So the market may make a bounce up in the coming weeks, but this will be used by slow big money to unload more of their holdings. Slow big money have a lot of illiquid PE holdings that they can't liquidate, so they must resort to selling more liquid publicly-traded equities.
Which brings us finally to this view: we are at the start of a major bear market.... either already started, or going to start soon. Trump has significantly damaged foreign investor confidence in USA. Foreign SWFs may also need to sell their US equity holdings to get cash to fund domestic priorities in response to Trump's 10% minimum import tariffs.
In conclusion, the coming buying demand is likely to meet significant selling pressure. If Powell does nothing, financial system leverage will not increase much, then buying demand will dissipate easily.
By the time he starts cutting rates again, it will likely be too late to stop the downwards worsening economic momentum.
No bear markets are the same. If you think this bear market will be short and shallow such that one can DCA all the way till it regains ATH, then make sure you have a nice secure stable job in case it isn't.
We are giving ourselves cancer to deal with the long hair instead of just getting a haircut.
