The FTSE 100
The DAX gained a little, too, up 0.5% to 6,392, even though it is Germany that will bear a large share of any future euro bailouts.
But indexes like these are no more than the aggregate of lots of individual shares, which it is sometimes easy to forget. Here are some of the most talked-about of today's FTSE movers.
Some nice gains
Healthcare Locums enjoyed an early 20% rise on news that American legal action against it is to be dropped, but it fell back to a 15% gain on the day, up to 3.9 pence.

Aer Lingus, the Irish airline, gained 18% to 1.10 euros on the confirmation of a new takeover bid from Ryanair Holdings. Ryanair, meanwhile, ended the day on 4.02 euros, 1% up.
Sage Group shares finished with a gain of 5.5% to 268 pence on news of an acquisition in Brazil.
Mixed retail news
Kesa Electricals ended the day down 5% to 52.5 pence. That's better than it might have been, as the former owner of Comet was down 9% in early trading after releasing disappointing year-end figures hit by "exceptionally difficult" European trading.
There were mixed movements in the fashion trade, as Supergroup shares rose 8% to 319 pence on no new tidings of its own -- though good results from H&M spurred interest in the sector. Next
Turning dirt into cash
It wasn't a good day for the oil and minerals exploration business, as Gold Oil slid 7.3% to 4.1 pence after releasing a disappointing trading update.
Others include Tri-Star Resources, down 11% to 0.7 pence after the release of its latest operational update; Regency Mines, down 6% to 1.65 pence after a laterite project update; and Petrofac
Even Cluff Gold, which gained 5% in early trading after a new gold discovery in Cote d'Ivoire, fell back to finish just 1% up on 68 pence. Sirius Minerals, however, gained 3% to 16.3 pence on news of a senior management appointment.
