I always bring my stock up to a decade's worth of components when pricing is reasonable and I maintain it at that level until prices lurch up again due to exceptional demand. This is because I expect there'll be another shortage in around ten years. This is my fourth one in about as many decades (though one was pretty minor), and it is probably the worst and seems likely to remain so for a bit. I don't recall any shortage in the two decades before the one in the first half of the 1990s, though I was less conscious of such things at the time. In any event, I still think the ten-year stockpile is a good strategy, and if you can manage to plan out your expected average year's shooting activities that far ahead, I would do so now and be ready to start gradually bringing your stock up when pricing finally normalizes again. It eventually should do that when the pending production capacity increases are all on line and raw material supply lines get back to something resembling normal.
