The common language way of expressing the efficient market h

The common language way of expressing the efficient market hypothesis is “there's no such thing as a free lunch”.How should one react when a stock broker calls up with a hot tip on the stock market?With skepticism.(88) There are thousands of individuals each day looking for hot tips in the market,and if a particular tip about a stock is valid there will be an immediate rush to buy the stock,which will quickly drive its price up.By the time the tip gets to your broker and then to you,the profit opportunity that arose from the tip (assuming that there was one) is likely to have been eliminated.Similar arguments can be made for bond markets and commodity markets.They are many “expert” in these markets,who take quick advantage of any news that affects prices.This economist's view that there are very limited profit opportunities around can,of course,be carried too far.There are clearly times when profit opportunities exist.(89) Someone has to be first to get the news,and some people have quicker insights than others.Nevertheless,news does get disseminated quickly,and there are thousands of people with quick insights.The general view that profit opportunities are rare is close to the mark.

我把大概给你译一下吧:
古语说得好:天下没有免费的午餐.当股票经纪人打电话给某人提供很多股票小道消息时,他会如何反映呢?当然会持怀疑态度.成千上万的人每天都在交易市场看着股票.如果知道有一支股票不错,他们都马上就去买.从而导致这支股票快速上涨.当这个消息传到你的股票经纪人那里再传给你的时候,这个赚钱的机会可能已经没有了.同样的观点可以用在债券交易市场和商品交易市场.这些市场中都有很多专家.他们都能从最新的消息中获取优势和利润.经济学家认为,在这其中只有很小的一部分挣钱的机会和方法会被广泛使用且仍然挣钱.当机遇出现的时候,时间是有限的,总有人会先得到这些消息,总有人的动察力是比较突出的.然而,新闻总是传闻得很快,这里有万千上万的拥有很强动察力的人.所以在大众的眼里就会认为如古语所说,认为挣钱的机遇是很少的.
