Here are some examples of insiders of companies involved in pushing up stock prices: **Case 1: Enron** - **Operational techniques**: - Enron executives used complex financial fraud methods to fabricate profits and cover up debts. They used tools such as special purpose entities (SPEs) to transfer a large amount of non-performing assets and debts off the balance sheet, thereby presenting good performance on the financial statements, misleading investors and pushing up stock prices. For example, by making false transactions with related parties, they inflated revenue and profits. - Company executives also issued optimistic profit forecasts and business prospects to investors, creating the illusion that the company is developing well, further attracting investors to buy stocks and pushing up stock prices. **Case 2: Wanfu Biosciences** - **Operational techniques**: - Company management inflated financial data such as operating income, operating costs, and net profit. Through a series of fraudulent acts such as forging contracts, invoices, and bank documents, they fabricated customers and transactions, making the company's performance appear to have grown significantly, thereby pushing up stock prices. - Using this false information for information disclosure, publishing false financial results in periodic reports, misleading investors' judgment of the company's value, attracting market funds to flow in, and driving up stock prices. These actions seriously violated securities laws and regulations, harmed the interests of investors, and ultimately led to the company's decline and legal sanctions. Regulatory agencies continue to strengthen their crackdown on such illegal and irregular activities to maintain the fairness, justice and transparency of the securities market.
