An investment advisor who espouses the alarmist (if no longer apocalyptic) economic theories of Harry Browne, Douglas Casey, et al. reviews offshore stock markets and spells out the ways interested individuals can participate--directly, by purchasing ADRs (American Depository Receipts), or via mutual funds. Day discusses key domestic industries (gold in South Africa, mineral resources in Australia); singles out promising issues (Japan's Fujitsu and Olympus Optical, among others); and, where possible, identifies local brokers equipped to serve US clients. He checks out many, but by no means all, of the globe's 70-odd securities exchanges--including those in Canada, Great Britain, Honk Kong, Singapore, Switzerland, and West Germany. Further, he analyzes the fixed-income instruments available in foreign capital markets, cautioning that such commitments demand foreign-exchange savvy. (Actual yields depend on the appreciation of national currencies against the dollar.) Day offers a country-by-country rundown on doing business with overseas banks. Beyond confidentiality, he notes, alien institutions routinely provide super-services like multi-currency accounts. While Day's banking material is ostensibly aimed at international investors, stay-at-home tax dodgers will find little cause for complaint: also covered are commodities (notably, precious and strategic metals), currency investing, insurance, and real estate. In assessing the latter, Day goes so far as to say that the illiquidity of property could prove advantageous if the US imposes exchange controls ""as it is bound to do."" A few imputations of this sort apart: a balanced, wide-angle perspective.
