Copper’s Rally Gaining Momentum as Historically Bullish Season Arrives
Copper tends to make a major seasonal bottom in November/December and then tends to post major seasonal peaks in April or May. This pattern may be due to the buildup of inventories by miners and manufacturers in anticipation of the construction season that usually begins in late winter to early spring. Auto makers are also preparing for the new car model year that often begins in mid- to late summer. Traders can look to go long a May futures contract on or about December 13 and hold until about February 24.
In this trade’s 52-year history, it has worked 34 times for a success rate of 65.4%. The average gain in all years is 5.4%. After four straight years of declines from 2012 to 2015, this trade has been successful in six of the last eight years with solid theoretical gains. Last year, copper was essentially flat from mid-December until mid-March before ripping higher through mid-May. Strictly following the suggested hold period did result in a minor loss, while holding positions longer (which was done in the Sector Rotation ETF Portfolio last year) resulted in well above average gains.
In the accompanying chart, the front-month copper futures weekly price moves (top pane), and seasonal pattern (bottom pane) are plotted. Typical seasonal strength in copper is depicted by a blue arrow and yellow shading in the lower pane of the chart. Last year’s seasonal period is visible in the top pane of the chart. Since copper’s mid-May peak, its trend has generally been lower with a brief surge in September. Copper’s August low appears to have been retested in November and now appears to be beginning a new trend higher. This new positive trend does align well with copper’s typical seasonal pattern.
