its no theory - And you havent stumbled upon a new idea - the SEC calls it stock manipulation or maybe you know it by the more popular term. Fraud
Manipulation is intentional conduct designed to deceive investors by controlling or artificially affecting the market for a security. Manipulation can involve a number of techniques to affect the supply of, or demand for, a stock.
They include: spreading false or misleading information about a company; improperly limiting the number of publicly-available shares; or rigging quotes, prices or trades to create a false or deceptive picture of the demand for a security. Those who engage in manipulation are subject to various civil and criminal sanctions.
