Why does it seem to be more difficult for investors to measure the capital stock of a firm like eBay rather than a firm like Ford Motor Company? Explain

What will be an ideal response?

Ford Motor Company is likely to have more physical assets like factories, machines and equipment that are easy to measure in market terms. However, a company like eBay may have few such physical assets since a large part of the value of their business is their good will - their reputation for conducting honest transactions and minimizing fraud.
