Domtar declines to 2-year low

The stock declined 6 cents to $5.18, after hitting $4.85 earlier in the session.

In a client note, Deutsche Bank analyst Mark Wilde said this is the "most challenging environment" in over a decade for Canadian-based forest-products companies, partly because the Canadian dollar and input costs have risen sharply over the past five years. A higher Canadian dollar can make exports more expensive.

Wilde rates Domtar "Buy."

Elsewhere on Wall Street, stocks rose sharply as oil prices declined following news from the Energy Department that showed U.S. supplies of fuel and oil were bigger than expected last week.
