I get the gist of your response and it certainly has some merit. But I would push back on the black or white presentation of your point - stock allocations certainly do matter, as you can easily confirm by playing with a few what-if scenarios in the past 12 months.

The high-level point of my parent comment was to not run away from market crashes, and instead to buy stocks that are a part of the collateral damage as opposed to those that are directly connected to the root cause of the sell-off. I think this strategy will work regardless of Fed's actions, within reason (eg: the financial system doesn't collapse altogether).
