The Sherman Act makes illegal any contract, combination, or conspiracy in restraint of trade or commerce and makes monopolies and attempts, combinations, or conspiracies to monopolize illegal. The Clayton Act regulate price discrimination, tying and exclusive dealing contracts, stock acquisition and interlocking directorates.
