The Eyeballs Have It: Searching for the Value in Internet Stocks
研究市场如何利用会计信息和网络使用指标（如独立访客数和页面浏览量）来评估互联网公司股票价值，发现毛利润和网络指标对股价有显著解释力，而净利润与股价负相关。
In this paper we provide insights into the manner in which (relatively sparse) accounting information, along with measures of internet usage, are employed by the market in the valuation of internet firms. Consistent with those who claim that financial statement information is of very limited use in the valuation of internet stocks, we are unable to detect a significant positive association between bottom-line net income and our sample firms’ market prices; in fact, the association is actually negative. However, when we decompose net income into its components, we find gross profits to be positively and significantly associated with prices. In addition, both unique visitors and pageviews, as measures of internet usage, are found in most instances to provide incremental explanatory power (in some cases considerable) for stock prices. We also separately analyze the e-tailers, and the portal and content/community firms (the p/c firms) in our sample. For the e-tailers we find that bottom-line net income generally has a negative association with stock prices (as for the sample as a whole), while a positive and significant association exists for the p/c firms. In this respect, p/c firms’ shares behave more like those of non-internet companies. Further, we find for the p/c firms that the incremental explanatory power of pageviews and of unique visitors is approximately the same; in contrast, pageviews has much greater incremental explanatory power for the e-tailers than does unique visitors. This suggests that pages viewed per visitor is an especially important metric for the e-tailers, as compared to the p/c firms.
