I presume you mean that it’s time for the undershoot—i.e. the overshoot on the downside—to begin.
Perhaps; however, for many commodities such as iron ore that tend toward megaprojects, elapsed time per se is generally not the main driver of increasing supply in response to higher prices. Rather, there are substantial financial, environmental, and political impediments to project development even when the raw material itself is relatively abundant. For instance, VALE has been negotiating with the government of Brazil for what seems like half a lifetime to expand its iron-ore output in regions of the country where mining is already entrenched.
Moreover, contrary to the ordinary meaning of the word commodity, quality matters a lot in some commodity markets, so increased supply may not have as simple an effect on pricing as one might assume. (This was discussed in a thread a few months ago culminating in #msg-73414315.)
So, what does all this mean for such stocks as CLF, VALE, and HES? Are they now unduly cheap even if commodity prices do retreat to some degree? I would submit that they are, but I’ve been getting killed on these names lately.
sorry for parsing your comment but just because a particular technique is useful in one country/area does not mean that it can or will be used in another country. The constraints include: geology, technical skills, and variable property laws. For example, once the Canadians demonstrated the effectiveness of SAGD many other countries thought it would solve their heavy oil recovery problems. Nopy. Another example: I think France has outright banned hydraulic fracturing and while it's been tried in Poland, it hasn't proven to be as successful there. Until recently people thought Argentina would be a wonderful place to use new production techniques. Folks are now having 2nd thoughts that, of course, have nothing to do with physics and geology.
