LONDON -- The FTSE 100 (FTSEINDICES:^FTSE) has seen little change this morning, down 0.15% to 6,713 as of 8:45 a.m. EDT, but it remains close to the its 10-year high of 6,732.4, set in June 2007.

So which companies are holding back the indexes today? Here are three whose share prices are falling and look set to lag the wider market.

Polymetal (LSE:POLY)
London-listed gold and silver producer Polymetal International is down 4.3%, continuing its fall since the turn of the year, when it was trading for as much as 1,218 pence -- today it stands at 606 pence.

Linked with the price of gold, which has been plummeting recently following the record prices in recent years, the likes of Polymetal are looking to cut costs ahead of further drops in the price of the precious metal.

Fresnillo (LSE:FRES)
Miners are not in fashion, and especially not gold and silver producers. Fresnillo isn't faring too well, either: Its shares are down 2.7% at the time of writing.

Many of the reasons for Polymetal's underperformance apply also to Fresnillo, which relies on the price of gold faring well. The beginning of the year saw it trade at about 1,810 pence, while it can now be picked up for 1,040 pence.

Eurasian Natural Resources (LSE:ENRC) 
Completing the set, shares in Eurasian Natural Resources have fallen 2.7% in early trade. This follows the announcement that a rejected consortium bid, announced last week, valued the company at 260 pence (comprising 175 pence in cash and 0.231 of an existing Kazakhmys share for each ENRC share).

The consortium consisted of Kazakhstan's government and ENRC's co-founders, and a successful bid would have cost about $4.8 billion. The consortium now has until June 3 to "either announce a firm intention to make an offer for the Company in accordance with the Code or announce that they do not intend to make an offer."

Finally, reliable dividends can more than compensate for the day-to-day ups and downs of share prices. So how about a company that's offering a 5% yield and could be set for some nice share-price appreciation, too?
