Query: extremely valuable and informative, though incomplete

for the economist in me, i resent the fact that the author didn't include the relevant quant / charts of the macroecon factors that precipitated the various extreme situations he describes. having said that, this book does describe the aforementioned factors, as well as detailed accounts of precipitiating factors, outcomes and, sadly, reoccurrences.if one had read this book prior to 99, one would have profited from the nasdaq meltdown. ---if that's not an endorsement, i don't know what is.
