The author notes that seemingly unrelated assets moved together during the 2022 selloff, suggesting common factor exposures like interest rates, tech, and consumer demand. The shift towards scenario analysis is a step towards better risk management, but the post underscores the difficulty in accurately modeling or intuitively understanding complex portfolio risks.
I have been trying to get a better sense of my portfolio beyond just allocations lately and I am realizing I do not have a good idea of what is actually driving the downside.

During the 2022 selloff I found that most of my portfolio moved together more than I expected even unrelated names.
Since then I have been trying to think more in terms of scenarios rather than sectors but it’s still pretty raw.
If you have been investing for a while, how do you approach this? Do you really model it or do you just get a sense of it after a while?
