What exchanges are Wall Street memes on?

Could you elaborate on the phrase "Wall Street memes" and the context in which they are discussed? Are you referring to memes that have gained popularity within the financial industry, particularly on Wall Street, and how they are shared or traded on certain platforms? If so, it's worth noting that memes are generally not traded on traditional exchanges like those for stocks, bonds, or cryptocurrencies. However, they may be discussed and shared on social media platforms or forums frequented by financial professionals. It's also possible that you're referring to a specific type of financial instrument or derivative that is somehow tied to these memes, but that would be a more niche and specific concept.
