Ballasts Category Jumps 12.4% in April Electrical Price Index

May 26, 2015
When the April edition of Electrical Marketing's Electrical Price Index showed ballast prices increasing more than 12%, it jumped off the page. What gives? Is everyone hiking ballast prices?

Electrical Marketing's Electrical Price Index, a proprietary data series provided monthly to EM subscribers, is seldom a volatile thing. Most of the time it's downright boring, because pricing changes of any size are rare in this market, especially with copper trading in a narrow range. If a product category changes price by more than 1% over a month, or even year-on-year, it's worth noting. In fact, since the beginning of the year, the trend of the overall price index has been flat to gently downward by tenths of a percent at a time.

In this context, the April index's report of ballast prices increasing more than 12% jumped off the page. What gives? Is everyone hiking ballast prices? Was there a supply disruption somewhere? Turns out the answer is likely more mundane. Global Insights’ Michael Montgomery, who prepares the EPI each month for EM, said the increase is probably a statistical anomaly due to the timing of a data release. We will watch it closely in case it turns out to be more than that. If you know another explanation, please share it with us.
