Prices plummeted on Spain's Ibex-35 stock market index for a third consecutive day on Friday, ending what was the worst week in trading in over eight months.

After four days of continued gains, the Ibex-35 recovered the 10,700-point mark on Tuesday, after it fell below 10,300 points.

Friday's closing figure of 19,282.90 means those three days accounted for losses of 3.52 percent.

The market opened at 10,450.00 points on Friday and suffered a torrid morning session in which it dropped as low as 10.252.40 points after just 1.5 hours of trading, before nerves steadied during the rest of the day.

Just three companies saw their share values rise on the day; Siemans Gamesa, supermarket chain Dia and Ferrovial, which made respective gains of 0.69, 0.50 and 0.02 percent.

Shareholders in Acerinox took a big hit with 4.50 percent lost from share prices, marginally more than Arcelor, which experienced a 4.45-percent dive, while Telefonica also had a difficult day with share prices falling by 2.74 percent.

Meanwhile, the risk premium rose to 105.1 points and interest on the 10-year-bond slipped back slightly from 1.45 to 1.43 percent.
