Bem, tudo está bem explicado no filme. Além disso, alguns pontos devem ser observados:
Isso tudo aconteceu entre 1989 e 1996:
Stratton Oakmont operou entre 1989 e 1996, este foi o pré- WWW era como nós agora (sem redes sociais, sem sites de revisão que lhe dirão o que é bom e o que é ruim, ...), então o boca-a-boca não terá tanto impacto como seria hoje em dia.
E o mais importante,
A Stratton Oakmont usou técnicas de "venda difícil":
De Wikipédia :
They recruit several of Jordan's friends, whom Jordan trains in the art of the "hard sell". The basic method of the firm is a pump and dump scam. To cloak this, Jordan gives the firm the respectable-sounding name of Stratton Oakmont.
O que é uma "venda difícil"? De Wikcionário :
A sales technique of pressuring the potential buyer to agree to a purchase.
O que é "pump and dump"? De Wikipedia :
"Pump and dump" (P&D) is a form of securities fraud that involves artificially inflating the price of an owned stock through false and misleading positive statements, in order to sell the cheaply purchased stock at a higher price. Once the operators of the scheme "dump" sell their overvalued shares, the price falls and investors lose their money. This is most common with very small corporations, ie "microcaps."
While fraudsters in the past relied on cold calls, the Internet now offers a cheaper and easier way of reaching large numbers of potential investors through spam email, bad data, social media, and fake news.
O que são "chamadas frias"? De Wikipedia :
Cold calling is defined as the solicitation of business from potential customers who have had no prior contact with the salesperson conducting the call. Cold calling is used to attempt to convince potential customers to purchase either the salesperson’s product or service. Cold calling is generally referred to as an over-the-phone process, making it a source of telemarketing, but can also be done in-person by door-to-door salespeople. Though cold calling can be used as a legitimate business tool, scammers can use cold calling as well.
