Maybe you should look at the 2008/2009 timeline. Pcl did considerably worse than the SP in that timeframe.
The 2008-2009 selloff involved one of the worst meltdowns in the US housing market ever. Timber is used in housing (duh). It's unlikely that the next consequential market downturn will be a carbon copy of 2008-2009.
Bottom line: On a risk-adjusted basis (including compounded dividends, of course), PCL has performed just fine compared to the S&P 500 or any other index.
