The favorable reception of Portfofio Manayzement Formulas exceeded even the greatest expectation I ever had for the book．I had written it to promote the concept of opfimal f and begin to immerse readers in portfolio theory and its missing relationship with optimal f．
     Besides finding fiiends out there，Portfolio Management Formulas was surprisingly met by quite an appetite for the math concerning money man-
agement．Hence this book．I am indebted to Karl Weber．Wendy Grau．and others at John Wiley&Sons who allowed me the necessary latitude this
book required．
    There are many others with whom I have corresponded in one sort or another，or who in one way or another have contributed to，helped me with，or influenced the material in this book．Among them are Florence Bobeck．Hugo Rourdssa，Joe Bristor,Simon Davis，Richard Firestone，Fred Gehm(whom I had the good fomme of working with for awhile)，Monique Mason，Gordon Nichols．and Mike Pascaul．I also wish to thank Fran Bartlett of G
&H Soho，whose masterful work has once again transformed my little mountain of chaos，my little truckload of kindling，into the finished product
that you now hold in your hands．
   This list is nowhere near complete as there are many others who．to varying degrees．influenced this book in one form or another．
   This book has left me utterly drained．and I intend it to be my last Considering this，I’d like to dedicate it to the three people who have influenced me the most．To Rejeanne，my mother,for teaching me to appreciate a vivid imagination；to Larry，my father,for showing me at an early age how to squeeze numbers to make them jump；to Arlene，my wife，partner,and best friend．This book is for all three of you．Your influences resonate
throughout it．
