Equities in a company do not appreciate if that company has no profits.
If a public corporation does nothing to maintain a profitable position ( if it does not produce anything or provide a service) it will soon have no investors.
That is true ( as the economists say) in the long run.
In the short run that does not happen. And even in the cases where the company has a sustained growth, the price of the shares is not proportional to any of the indicators for that company .
For example , Microsoft's equities were sold at $37 by the end of 2013
By the end of 2014 they had a price of $47 while total revenues increased from 77 billion to 86 billion.
Regardless of that you can still profit on declining equities by short selling them.
