This bull market started on March 23, 2020, after the markets dropped 34% due to Covid. So this bull market is not old, rather, quite young. The markets "seem" overvalued at the moment, but with the light at the end of the tunnel on Covid growing by the day and the new stimulus about to jumpstart GDP growth not seen in decades, with predictions that it will last into 2024, and the possibility of infrastructure further stimulating growth, I don't see a major pullback as likely in the near term.

I was about to make the same point on bull market.
However, regarding "shoes" dropping often major pullbacks are unanticipated. See Asian financial crisis, dot com bust, pandemic, just about all the major declines happened suddenly. Such shocks are possible.
On the other hand, inflation/higher rates, which would hurt both stocks and bonds, are highly anticipated by the market, but still would do a lot of damage. Go back to the Taper Tantrum of 2013.
A major geopolitical event involving China, Iran or NKorea for example could result in a hit to the markets. These may be unanticipated right now but they are far from remote possibilities.
My strategy is just to be ready for these based on longterm strategy. A market swoon is a good time to buy equities.
And the only things more expensive right now than stocks are bonds. So i am limiting duration everywhere.
