Why it worked
The video effectively uses simple animation and clear explanations to break down a complex topic (the two sides of finance). By providing valuable educational content, it naturally leads viewers to explore the creator's other offerings, such as the promoted cheat sheet, through the bio link.
Summary
The video explains the two main sides of finance: the buy-side, which manages money (asset managers, pension funds, hedge funds), and the sell-side, which provides services (investment banks, brokers, research firms). It highlights that every trade connects these two worlds and that careers exist in between them.
