Why buy stock of something you don't like? Surely you can find other profitable investment options that also then don't support the thing you don't like?
Buying shares in a company doesn’t benefit its operations, like making a product, directly. Hence, buying shares != support company’s products, however counterintuitive that feels.
Maybe during a never-ending bull market … but all bull markets end … look at the “lost decade”
Argument here is that buying shares (other than during specific events like an IPO) affects the shareholder, not the company's products.
So whether or not you buy shares has no relation to supporting the company's products. The latter happens when you buy or not buy their product.
