As for old investors switching over from stocks to stamps, the biggest impact is made by stock clubs which force up prices by speculation and rumors. They use exactly the same methods as in "cooking up" stock prices--nurturing, swapping and killing--to play stamps. Thus the more the price is nurtured, the higher it goes.
至於由股市轉向郵市的投資老手，其中以股友社介入炒作哄抬影響最大，他們用炒股票的一貫手法﹘﹘養（大）、套（利）、殺（掉）來炒郵票，郵價就這麼愈養愈高了。
