Over the long term, I agree that constant DCA is the real strategy. But I was down 2 years' salary during the covid crash. I became increasingly concerned with capital protection because of all the supply chain issues and geopolitical tension. I looked around for something more conservative to ride out the uncertainty and I landed on the Permanent Portfolio. Sure, I missed out on some slight gains than if I had stayed 60/40, but the peace of mind was worth more.
I'm not saying to invest in the Permanent Portfolio necessarily, but I am using it as a shield during uncertainty and it has worked out well every single time. I switched from 60/40 to the PP before the election and gave myself 6 months to switch back to 60/40. Holy crap, I'm actually up quite a bit since November, '24 on account of gold skyrocketing. I still plan to return to 60/40 at the 6 month mark, but I think I'm down like 2% this past week. I sleep like a baby with this portfolio.
So, the point is. You can still stay invested and keep investing AND change your risk profile without outright changing your gameplan. This has nothing to do with timing the market, and more so having to do with keeping your risk at a comfortable level.
