North American Electronics Sales Performance Mixed in January

North American electronics industry sales growth remained positive for electronics manufacturing services (EMS) in January, while sales growth plunged into negative territory for printed circuit boards (PCBs) and semiconductors. These year-over-year growth rates reflect three-month rolling averages.

The leading indicators remained positive in January. The U.S. Purchasing Managers’ Index (PMI), which tends to lead industry sales by two to six months, recovered from a downturn in December and remains positive. The PMI has fluctuated in recent months but has not revealed a clear upward or downward trend. It has been positive (above 50) for over two years. The 3/12 rate of change for U.S. new orders for electronic products, which leads industry sales by one to three months, held steady in January in positive territory.

Another leading indicator is IPC’s PCB book-to-bill ratio. It is based on three-month rolling averages of orders and sales, and normally leads industry sales by three to nine months. The book-to-bill ratio has been declining since it peaked in February 2018 but strengthened slightly to 1.06 in January. Ratios above parity (1.00) indicate greater demand than supply, which may be a precursor of sales growth for electronics manufacturers, especially when a run of positive ratios over several months is seen. Ratios below parity indicate the reverse.

These indicators suggest the likelihood of continued but slower sales growth in the industry, with possible volatility, through the first half of 2019.
