Market manipulation comes in many forms. For a wrong that some say started life with groups of men dressed in Bourbon uniforms spreading false information in cod French accents, the speed of change has accelerated dramatically in the modern era, via the Internet, novel forms of electronic communication, ultra-fast computer-generated trading, new types of financial instruments, and increased globalisation. This means that opportunities for carrying-out new forms of manipulation now exist on an exponential scale. Looks at the mechanisms, criminal and civil, to confront market manipulation, its enforcement regimes, legal and evidential rules and potential loopholes. Shows how every individual involved in market transactions can fall foul of the law if they do not ensure integrity in their dealings. The ‘tricks’ used by those seeking to benefit from this special category of fraud and the relationship of dedicated provisions to the general law is outlined, with key statutory provisions set out in an appendix.A valuable accompaniment to The Little Book of Insider Dealing (Waterside Press, 2018).
