Issaquah’s Costco Wholesale Corp. got an upgrade from a Credit Suisse analyst Wednesday, and the stock responded with a 3.33 percent price increase.

Analyst Michael Exstein said in his note to investors that Costco’s in-store traffic is at “historically high levels.”

If the economy begins reviving, the wholesale retailer could profit as customers begin buying more discretionary goods, he said.

Even if the recession remains with the country, Costco should be able to hold its own with prices at stable levels, he said.

Exstein improved his rating for Costco from “neutral” to “outperform.”

Costco closed at $48.78 Wednesday, up $1.57.

Meanwhile, another local company, Tacoma’s TrueBlue Inc., didn’t profit from an analyst’s upbeat remarks. The temporary labor provider’s stock fell 2.31 percent Wednesday.

That’s in spite of generally favorable comments by Deutsche Bank analyst Paul Ginocchio regarding temporary labor companies such as Milwaukee’s Manpower Inc. and TrueBlue.

Ginocchio said that rising overtime by factory workers and a boost in average workweek hours is a sign favorable for temporary staffing companies.

Both Manpower and TrueBlue, he said, are in a good position to see their demand for workers rise as the economy revives.
