The business section does has one interesting story in it about the shorting in respect of a number of companies (as indentified by level of stock-lending). Here's what it says -
According to figures from City research firm Data Explorers, 18.28 per cent of Wetherspoon's shares are on loan, nearly as much as Northern Rock's (20 per cent) at the time it became the first UK victim of the credit crunch last year. The proportion of Punch's shares on loan stands at nearly 17 per cent.
Mitchells & Butlers, another pub company, has 9.35 per cent of its shares on loan, while retailer Debenhams has 12.7 per cent, says Data Explorers.
Debenhams is the interesting one for me, as it has become one of the examples people like to give of a bad private-equity buyout (take private, load up with debt, refloat). So perhaps not surprising to see market sentiment being pretty negative about it.
