PTE Re-tell Lecture 真实讲座练习题:为何股票价格如此不稳定

在PTE中,无论是Summarise Spoken Text 还是 Re-tell Lecture的考题大都是从真实的讲座或者演讲中截取的中间经常经常夹杂很多不同的环境音.很多同学都反映有时未必是听不懂,而是听不到. 鉴于此,墨尔本悉尼文波雅思PTE专门为大家总结了真实讲座的PTE练习音频,相比新闻音频来说,整体更加接近PTE考试的真题,内容方面,我们也会为大家提供考试中存在的近似题,最近我们会持续更新,敬请期待!

The subject to this mini lecture is why are stock prices so volatile in comparison to prices of goods and services. Let me offer two quick thoughts on this question. First, buying and selling stocks is easy, quick and low-cost. This is not the case for most other things. The ability to trade things cheaply and quickly can be a cause of price volatility. This argument becomes more convincing when we consider basic features of human behavior, and this is my second point. On the one hand, risk aversion or fear can cause people to sell stocks when prices are falling, pushing prices down even further. On the other hand, let us be wealthier or greed can cause people to buy stocks when prices are rising, pushing prices up even further. In short, human nature and conjunction with sophisticated trading systems are part of the reason stock prices move so much, while left prices and many other things. Thank you.
