Marketing is one of the most impactful reasons for buying stock market apparel. By giving out apparel as a gift, you can get people interested in stock market investments.
For example, envision that you buy a hooded sweatshirt that says “love me a bull.” If the gift recipient is not an investor, they are going to ask what a bull is. This may lead them to start investing in the stock market, which naturally helps all investors.
If the gift recipient already invests, it may encourage them to sink more capital into stocks. They may be reminded to check their portfolio and make a transaction.
