Ay yes, theres always those who pay attention only to the shareprice, ignoring all else.

You must be a believer in the Efficient Market Hypothesis?

"What Is the Efficient Market Hypothesis (EMH)?
The efficient market hypothesis (EMH), alternatively known as the efficient market theory, is a hypothesis that states that share prices reflect all available information and consistent alpha generation is impossible."

I assure you, value investors are certainly not believers. There's value for a reason, often the result of the market, economy, or the mis perception of investors.
For example, those who continually look to the shareprice as a gauge of a companies performance in its space, will never recognise value when its there.
