The LME opened in 1877; it has continued strengthening since then, and became recognized as the global benchmark for the metal market. Major producers and consumers use LME contracts for hedging price risks, and for the reference price for spot and future prices. Park and Lim (2018) provided a good discussion of the LME. They found that the LME was an inefficient market due to financialization by institutional investors.
See details in Metal Bulletin (http://www.metalbulletin.com/Glossary.html). The CWs are the ratio of CWs to total warrants, where total warrants are the on warrants and canceled warrants.
This information is a valuable investment factor of consumption trends, which can provide a meaningful implication of possible future price directions.
The LME does not report intra-day data and tick data. It is not possible to compute daily realized volatility measures for LME markets (Figuerola-Ferretti and Gilbert 2008). They used monthly rather realized volatility data.
Figuerola-Ferretti and Gilbert (2008) concluded that the LME aluminum and copper scedastic processes are both highly persistent. They argued that the strong symmetry of the two processes implied that the processes may be the outcome of common market microstructure factors.
Koitsiwe and Adachi (2018) reported that commodity assets under management by financial investors dramatically increased in value, from about $13 billion in 2003 to $450 billion in 2011. Irwin and Sanders (2012) reported that a total of $161.2 billion was invested in commodity index investments as of 31 March 2010. A total of 78% of index investments were in the U.S. futures market, which invited major index funds with rising trading volumes.
