LPX is a long-term hold and may continue to drop a bit in the short-term. If this $$$ is not part of your long-term portfolio, you may be SOL. IF you have capital gains to use against tax loss, it may be prudent to sell and buy back in 30+ days assuming that LPX will not move significantly up in the near term. Be aware that you can only deduct $3K or so of the loss each year in your itemized deductions if you do not have off-setting capital gains (talk to your accountant). Borrowing money to buy stock is a short-term strategy that will send you to the poor house. Borrow if you have bills to pay, but be smart about using it in the market - that's too close to day trading. You will lose your ass doing that over time. The amish lifestyle would be no picnic. If it were me, I would sit tight and hold for the long-term (3-5+ years) assuming that I did not need access to this money in the short-term. Good luck with your decision.
Based on the Barron's comments regarding the dividend, this could be a good entry point for a long-term hold. Even though the current price likely prices in the dividend story being cut and/or eliminated in order to pay down the debt, I will wait to see if this actually happens. If it does, I would look for a short-term price drop presenting a better buying opportunity. If it does not, I will just buy-in at that point - probably still south of $9.
