As someone who researches military history, and invests in stock market shares, I was interested in seeing the two, laid side-by-side. Mr. Biggs is on an important and novel track by juxtaposing war/political events and securities trading; he summarizes the course of WWII (and much of the first half of the 20th Century relating to it, e.g., the Weimar economy or post-war Japan and Korea).
(As regards Weimar, Biggs notes, "The message for wealth preservation is important. Hyper-inflation occurs from time to time, and basically it is one of the Four Horsemen in drag.") However, he has some unfortunate leaps in narrative: in one page he goes from the 1937 U.S. recession, to the 1987 stock crash, to Adm. Yamamoto's time as naval attaché in Washington - in three successive paragraphs.
To be sure, the author admits he is not a military historian, so I can accept the anecdotal parts (that is, the "war stories" about generals and political leaders), with what happened, contemporaneously, to securities markets. Still, I would have liked to have had some insight, say, into what the $3 billion gamble on Boeing's B-29 program, or Goodyear's getting drafted into building Corsair fighters, did to their value per share. Or, for that matter, I'm curious how he can talk about postwar Japanese property values (i.e., under MacArthur and later) and not talk about the Bretton Woods economic system, which was (for better or ill) one of the most decisive results of that war. I could've used less of isolated incidents like the Jervis Bay naval battle and more on British commodity shortages, which were what the enemy was trying to create by interdicting the convoys. He does, however, cover the losses of fortunes in Italy, France, Germany and Eastern Europe in some detail and insight -- even evoking, in passing, the Gone With The Wind misfortunes of the Civil War South as a comparison. Scarlett O'Hara was fortunate not to have her estate outside, say, Krakow.
Mr. Biggs is very worthwhile when he gets into how wars (and post-war periods) can create, destroy, or shelter wealth - not just securities but real property, art, gold, and cash. He shows how land can survive a war or be expropriated by the winners, and how shares can (at least overall, judging by his research) prove worthwhile over the long term. It helps, as he shows, if you don't lose a war, don't go into debt financing one, try to diversify your wealth and have an escape hatch -- your nest egg isn't worth much if you don't catch the last plane out of the capital and you wind up behind barbed wire.
His lessons on how wealth is destroyed in wartime are more insightful in the final chapters, and perhaps worth wading through the back-and-forth war stories. Indeed, Mr. Biggs starts a new discussion of comparative history and economics, from the viewpoint of the frontline investor, and the book's lasting value may be in sparking more research and discussion.
