Every time there is a fall, discussions about whether the bull run is still ongoing become heated.

From my perspective: It doesn't matter much whether there is a bull run or not; managing your own risks and preparing for all situations is more important.
In the market, one always has to take risks, either missing out or getting trapped.
Consider carefully what kind of risk you are willing to take at this moment and whether the worst and best scenarios are truly acceptable. Then adjust your position to a state where all situations are acceptable.
