Having read both of his prior books numerous times, which were trading concept educational, this is a total disappointment. This book should have been a junk mail flyer promoting an investment package or direction to an informational website of which we all get far too many.
The book is 194 pages, the first 34 of which give some meager background on commodities investing. Page 35-194 (the end) is nothing but promotion of why to invest in the Standard and Poor's DTI INDEX ... an index of commodity trading he created and is compensated for. It contains pages and pages of supporting statistics to induce one to purchase the index. There is not even acknowledgement of incredible new tax advantaged products such as the Swedish Bank's Jim Rogers Raw Materials Index offerings. The index may actually work, in fact, it wouldn't even surprise me if it did, but to have to PAY for the right to learn about it is a sorry promotional use of the "Trader Vic" identity ... which is assumed to be one of trader education, not self promotion.
Having purchased some 100+ books from AMAZON since its inception (mostly of investment and computer topics), this one is the first I will have ever returned!
It troubles me to take the time to rate a book poorly, but to make people pay for a sales pitch, rather than at the promoter's expense, is something these publishers need to cease ... this one obviously fell for the marketability of the "Trader Vic" brand.
A great disappointment indeed!
