LONDON -- The FTSE 100 (INDEX: ^FTSE) has been looking stronger of late, and today it continued to recover from its long-term slump. By midday it had put on another 19 points to reach 5,660. The lack of fresh disaster news from Europe appears to be doing the markets some good.

But an index is only the aggregate of its component companies, and there have been plenty of individual price moves across the various FTSE indexes this morning. Here are three shares being punished.

Mine collapse
Nickel and zinc miner Talvivaara (LSE: TALV.L) took another hit today, falling 14% to 146 pence as a result of a weak operating update.

The firm saw its second-quarter production hit by a number of problems, including excessive rain and flooding and a stoppage caused by a fatality in April. There has been a production increase over the previous year, but full-year 2012 guidance is now unlikely to be achieved.

This is disappointing after the 2012 share-price slump looked like it was reversing. But things are tough for all miners these days, with most mining shares being down on the year.

Cue the wrecking ball
Despite having a great June and publishing a strong half-year update today, homebuilder Persimmon (LSE: PSN.L) saw its shares fall 9.5 pence (1.5%) to 625.5 pence.

Although the company completed 6% more homes than during the same period last year and achieved an average selling price 7% higher, a report just released suggested that the construction sector fell at its fastest pace in two and a half years last month, and it took the shine off Persimmon's good figures.

It also hit across the sector, with Bovis Homes down 1.6% to 479.5 pence, Barratt Developments falling 2% to 142 pence, and Taylor Wimpey dropping 1.2% to 49 pence.

The well is dry
Oil and gas explorer Salamander Energy (LSE: SMDR.L) released an update today and saw its shares promptly drop by 2.5% to 167 pence.

The reason? The firm's Far East-1 well in its prospects in the Gulf of Thailand has turned out to be dry -- practically so, anyway, as it was actually wet, but the fluids there consisted only of formation water.

The well will now be plugged, but the firm is still positive about its overall prospects in the region.
