'Professor Barnes’s book has made an important contribution to how we think about stock market efficiency by questioning the ECMH hypothesis and tracing the history of financial bubbles and manias, as well as by providing useful insights regarding how financial bubbles can be caused by market manipulation and other types of market abuse.
