For the person with substantial funds to invest, this is a valuable survey of possibilities from speculative to thrifty. The editors follow a run-down of investment areas with chapters on choosing a broker (with a view to possible conflicting interests); the potential of marketable bonds for different categories of investors; the choice of mutual funds with their various frailties; the double play in closed and funds; the prospects of new issues; the potential of foreign stocks issued abroad; speculating on the foreign exchange and dealing in commodity futures -- both definitely for the sophisticated (or game) investor. The editors weigh theories re playing the rket with charts from Dow Theory through Technical Analysis to point-and-figure theory, on which they are bearish; they evaluate Dow-Jones against Standard & Poor, with a lean to the latter for technical stocks. There is the question of how much a stock should be worth in relation to its earnings, and the parting shot on how to stay rich if you are so (some 1,700,000 individuals have assets of $100,000 or more which may profitably send them to professional managers of money in banks or investment management firms). An alert, discerning once-over for the intelligent investor who wants an idea of the odds in less obvious areas as well as more familiar ones.
