If you bought equities with the idea of making a capital profit, its too late. If you bought equities for the dividends, then ask yourself the question "will what's going on hurt the company's profits?". If you are looking at a company whose profitability may be hurt (banks, luxury goods, retailers). then think about switching; if profits are unlikely to be hurt (shipping, food, infrastucture equipment, petrochemicals) then stay with them and allow the turmoil to wash past you.

Seen it all before.
