The Risk of a Yield Blowout in Junk Bonds

As yields rise, investors will come back in their risk curve to treasuries. It seems that all of the risk of yield blowout should be in risk of your investments such as high yield and junk bonds. Why wouldn't you play the trade that way rather than short treasuries? Many thanks. I actually think that quantitative tightening is not something that you mean that you should go out and be buying or selling treasuries because of it. And so I'm definitely watching that.
