The increase in the margin rate (保证金率)from 50% to 70% was not an attempt to stem any rampant (猛烈的)speculation on the part of the public-actually the market seemed technically quite strong, with public participation essentially dignified-but rather an attempt by the Federal Reserve Board to preserve the sound underpinnings that existed in the market. Naturally, such a move had a____1____chilling effect upon prices but if the FRB had been preoccupied with undue speculation, the increase might have been to the 80% or even 90% level. Such increases in the margin rate is a____2____of a strong stock market and since 1989, such increases have resulted in interim market highs over twelve months later.

When investors-both the public and the institutions-are nervous and____8____they definitely hesitate to buy stocks: they seek low price/earnings multiples and high____9___. These same investors-when they are in an optimistic frame of mind--become far less____10___ with yields and more willing to pay a premium( high p/e multiples)for accelerated growth. If the public's attitude towards the auto industry is any measure, then this period seems to have been one of optimism.
