Blue Sky Laws


BLUE SKY LAWS are state laws designed to prevent fraud in the sale of corporate securities. These laws preceded federal regulation of securities, which began in 1933. Kansas enacted the first statute in 1911, and by the end of 1923, forty-five of the forty-eight states had followed suit. The term "blue sky" arose when the U.S. Supreme Court stated in Hall v. Geiger-Jones Co. (1917) that the laws were intended to prevent speculative schemes based on nothing more than "so many feet of 'blue sky.'" The requirements of blue sky laws vary from state to state, but generally stipulate that securities offerings and brokers be registered.

Learn more about citation styles

Citation styles gives you the ability to cite reference entries and articles according to common styles from the Modern Language Association (MLA), The Chicago Manual of Style, and the American Psychological Association (APA).

Within the “Cite this article” tool, pick a style to see how all available information looks when formatted according to that style. Then, copy and paste the text into your bibliography or works cited list.

Because each style has its own formatting nuances that evolve over time and not all information is available for every reference entry or article, cannot guarantee each citation it generates. Therefore, it’s best to use citations as a starting point before checking the style against your school or publication’s requirements and the most-recent information available at these sites:
