Finding Value in Numbers rekindled the same excitement I felt learning under legendary investor Michael Price, and it will do the same for you. This isn't another reheated homage to Warren Buffett's greatest hits; it's a modern toolkit for value investing in an age defined by intangibles, growth dynamics, and the rise of new-economy businesses. Ehsan Ehsani shows that pure value investing, activism, and special situations share the same uncompromising rule: the numbers must work.--J. Dennis Jean-Jacques, founder and CIO, Ocean Park Investments

Ehsan Ehsani has pulled off something of a miracle. His investing guide delves deeply into the nuances of computing and interpreting the crucial financial metrics that should be in every intelligent investor's toolbox, and yet it remains surprisingly approachable. His well-chosen examples bring the applications to life. Bravo, I say.--Bennett Stewart, creator of EVA (Economic Value Added) and former senior partner, Stern Stewart & Co.
