During the weeklong slide on Wall Street, stocks of regional interest generally outperformed the market through Friday.

From the Dow’s 666-point drop Feb. 2 through its 1,000-point decline Thursday and its week-ending close Friday, many of the region’s most-watched companies have seen their stock prices fall, but not to the degree of the market.

The Dow finished at 26,186 on Feb. 1, and stocks road a daily trading roller coaster through the week to its Friday close, when the Dow finished 24,191, a 1196-point drop of 7.6 percent.

In the six trading days since the market close on Feb. 1, Clearwater Paper Co. has posted the largest percentage decline among regional stocks of interest, dropping 24.7 percent from its Feb. 1 after-market closing price of $46.80 to $35.425 after close Friday.

After running counter to the Nasdaq composite’s drop Feb. 2 with a gain of 2.8 percent, Hecla Mining Co. ultimately fell 8.6 percent from the Feb. 1 to Friday’s closing. In that same period, the Nasdaq fell 511 points, or 6.9 percent.

Avista Corp.’s stock price is the only one among 14 tracked by The Spokesman-Review during the period that posted a gain Friday over its Feb. 1 closing price.
