I looked into the logo design (which I originally thought would've been designed specifically for the movie) and I found out that it is actually a real company, which suprised me as I didn't know the movie was based on a true story. Stratton Oakmont was a Long Island, New York 'over-the-counter' brokerage house, that is mainly known for the defrauding of many shareholders, which eventually lead to the downfall of several executives and the closing of the firm.
I think the logo looks incredibly trusting (and so must of a lot of big firms), for example the typography used is a serif font, which makes it looks like an old company with good values. Also the fact that a lion is the main logo, and lions generally represent strength and bravery. I also think the fact that the grid used behind the lion was incredibly slick, as it sort of looks like a stock market sheet, but also it is morphed so it looks like the Earth as well. Overall, I think the logo is incredibly successful and definitely portrays what the company apparently stood for.
