Michael Hsing, CEO of Monolithic Power Systems, filed a Form 4 disclosing a stock sale dated September 30. Thirty days later he appeared on the company's earnings call and told investors that the chipmaker sees accelerated growth and that its diversified growth strategy is paying off.

Form 4 filings are mandatory disclosures to the SEC that report insider transactions typically within two business days of the trade. The filing itself is a matter of public record, meaning the sale was visible before Hsing stepped onto the call to deliver upbeat commentary about the company's growth trajectory.
