If You Want To Know How The Economy Is Doing, Watch The Services Sector

For more than a year, we’ve been watching the unfolding -- sometimes slow, sometimes rapid -- of a real collapse in the commodity space. As we’ve noted in previous letters, this collapse is partly cyclical -- the result of overcapacity built during a boom time, a process which has been repeating itself in commodities since time immemorial. The collapse is also partly secular -- the result of technological revolutions in the extraction of tight oil and gas, and of China’s once-in-an-economy shift as its center of gravity shifts from manufacturing to services.

That collapse, along with many other factors, has contributed to troubles throughout emerging markets and industrial production weakness worldwide. Jumpy market psychology in 2015 has meant that economic data points are seized on and interpreted with a negative spin. Thus, we have ended up with a drumbeat of pessimism pulling down market psychology.

We want to point out a particular problem with pessimism arising from disappointing manufacturing data.

Economies are generally divided into three parts: primary, secondary, and tertiary. Primary includes agriculture (and natural resource extraction, in some models). Secondary includes manufacturing. Tertiary includes services.
