Explanation:

The Sailor-Kefauver Act was a United States federal law passed in 1950 that amended and strengthened the Clayton Antitrust Act of 1914, which amended the Sherman Antitrust Act of 1890. The Sailor-Kefauver Act was passed to eliminate a loophole to link firms to the acquisition and acquisition of assets that are not direct competitors.The Clayton Act prohibited stock purchase mergers, the competition was reduced, and smarter traders were able to find ways to buy competitive property around the Clayton Act. Under the Sailor-Kefauver Act, asset acquisition competition decreases, and that practice is banned.
