Professional investing usually comes down to a matter of finding good value at a low price. You can, for example, buy a value, wait for its price to rise, then sell it and make your profit. The prices of financial instruments change all the time, and although they tend to get closer to the value, if they deviate from it for some time, they also move due to other reasons. This book is dedicated to just such some “other reasons”. It's about how psychology can cause price movements in financial assets.
