Ceramic Fuel Cells, had an unusually large turnover of shares today, 13 million shares compared to a more usual 1 million or less. This is prompting bid speculation that a large "White Goods" manufacturer - i.e. a maker of fridges, freezers, washing machines, dishwashers etc. - wants to buy them outright. Having reread my last post on the company from March, I'm reminded that they've got quite a big interest in Germany. So if I was to speculate who the mystery bidder is, one big German white goods manufacturer who might well be interested is Bosch.
