Lumber costs have skilled one in every of their largest and quickest plunges in historical past— with the spot futures contract dropping greater than $670, or 40%, in simply 25 buying and selling periods.
It’s human nature to attempt to discover that means on this, for the reason that various is to just accept that worth adjustments this momentous are nothing greater than merely random fluctuations. None of us like to just accept that our funding portfolios may very well be topic to such merciless twists of destiny.
A method through which some are discovering that means in lumber’s decline is through a market-timing indicator primarily based on the ratio of lumber
One study discovered that when the ratio is greater than the place it was 13 weeks beforehand, circumstances must be favorable for U.S. shares. When it’s decrease, U.S. Treasury bonds are most popular.
Not surprisingly, given lumber’s current plunge, this ratio’s present message is bearish for shares. (See chart under.) To assist decide how a lot weight to position on that message, I examined the ratio again to 1984 — which is how far again information prolong on FactSet. For every week since then, I calculated whether or not the ratio was greater or decrease than the place it was 13 weeks beforehand.
The desk under stories the frequency of a rising market as a operate of whether or not the lumber-gold ratio’s 13-week change was optimistic or adverse. I used the Wilshire 5000’s Complete Return Index because the market benchmark.
Discover that the lumber-gold ratio makes little to no distinction to the frequency of a better inventory market. This implies that the current downturn within the lumber-gold ratio will not be as alarming because it in any other case would possibly seem.
After all, it’s potential that though a decline isn’t extra possible when the ratio’s 13-week change is adverse, the declines that do happen are extra extreme. The desk under stories the related information, which inform an analogous story because the desk above.
To make certain, this dialogue just isn’t an exhaustive evaluation of the lumber-gold ratio’s potential worth. There could also be different methods of slicing and dicing the information that uncover methods through which it may be of use to traders. Nonetheless, the information would appear to recommend that the current downturn within the lumber-gold ratio just isn’t in and of itself an enormous trigger for alarm.
None of those outcomes ensures that the inventory market gained’t expertise a correction in coming weeks, and even start a bear market. It very a lot may, at any time, given how overvalued the stock market is. My level is that, so far as I can see, the declining lumber-gold ratio just isn’t an extra cause for predicting such a downturn.
Within the meantime, chances are you’ll wish to give the inventory market the good thing about the doubt. That’s due to one other commodity-market-based ratio that a peer-reviewed academic study has discovered to have a superb file forecasting the inventory market’s 12-month return. This different ratio is the value of gold divided by the value of platinum.
I most recently wrote about this ratio in February. Although the ratio is quite a bit decrease at present than the multiyear excessive it set on the backside of final March’s waterfall decline, it nonetheless is above its long-term common. Accordingly, although the inventory market’s upside potential over the following 12 months is nowhere as robust because it was as 12 months in the past, it nonetheless is above common.
