How they're profiteering, and how to spot it

The article doesn't say unfortunately, satisfying itself with the easier comparison: their market value has stagnated. Still, it's another statistic to bash profiteering executives with.

Herald Investment Trust is sick of private equity firms helping management buy out its investments.
Chairman Julian Cazalet says Herald has invested money in companies when they are risky only to see the reward taken by others. Unlike small private investors, though, Herald can resist, which in the case of Andor Technology paid off. Post failed buy-out the shares rose from 73p to over 500p.

I'm adopting Expecting Value's 'holding ratio' to judge managers' financial commitment to long-term prosperity
The ratio divides the value of an executive's shareholding by his annual salary.

His shareholding is worth 25 times his annual salary.
