Nov. 15 (Bloomberg) -- The Czech Republic’s PX equity index dropped to a six-week low, sliding 1.7 percent to 892 at its 4:28 p.m. close in Prague.

The following were among the most active stocks in the Czech market today. Stock symbols follow company names.

Erste Group Bank AG (RBAG CP) of Austria fell 4.5 percent to 361 koruna, its lowest close since April 2009. Komercni Banka AS (KOMB CP), the Czech unit of Societe Generale SA, fell to its lowest in 1 1/2 months, sliding 2.7 percent to 3,075 koruna.

Financial companies led European stocks lower as the cost of insuring French bonds climbed to a record and Spanish yields rose at an auction, boosting concern the euro-area’s debt crisis will worsen.

New World Resources Plc (NWR CP), the biggest coking-coal producer in the Czech Republic, declined 2.3 percent to 136.7 koruna, headed for a five-week low. Commodities tumbled, with Europe’s benchmark coal futures contracts slid as much as 0.6 percent. They last traded unchanged at $117 a metric ton in the Netherlands.
