I guess many things can be a great investment for collectors, IF you're willing to buy and sell. Typically in the collectors market the money is made by the middle man. Its funny, people complain about paying any stock commissions, but don't consider the outrageous fee they are paying in commissions for gold, silver, or even furniture. A collector's item, just like Bitcoin, is only valuable if you have someone who is willing to pay top dollar for it.
Anyway, $SWBI is interesting due to the last two events which caused the stock price to leap. ....One was Obama stating he wanted to take away all personal weapons. Everyone I knew who was a gun owner, first loaded up on ammo, then additional weapons. If Obama wanted to create a market, he couldn't have done any better.....the other thing was Covid. People always talk about what to have in case of an apocalypse...water, fuel, canned goods, gold....the answer is simple, a bigger gun than your neighbor. Sadly, people would rather steal from their neighbor than do their own prepping. Covid made people afraid of running out of goods, so they bought guns. I used to think I'd easily survive a zombie attack. Not any more. I don't have the selfishness necessary to put myself before others.
The other place to find that selfishness....just about every penny stock board, where these people claim to be "the good guys".
I'm rambling again.
BTW, SWBI's P/E is around 13, and pays close to a 5% dividend that rises annually. You may want to look again
