Worldwide shipments of traditional PCs (desktop, notebook, workstation) totaled 60.5 million units in the second quarter of 2017, posting an on-year decline of 3.3%, according to IDC. The results tilted just above the previous forecast that called for a decline of 3.9%, and hewed to the expectation that unlike past seasonal patterns of significant positive sequential growth, second quarter volume showed only a modest uptick from the first quarter.

Whereas one factor affecting shipments during the past several quarters was an inventory buildup caused by shortages of key components such as solid state drives (SSDs), the second quarter operated under less harsh constraints, though in some instances component shortages still played a role in driving shipment dynamics. Moreover, as expected, the increased bill of materials (BOM) cost due to the shortage also began to impact the final price of systems, which was also factored into IDC's original assumption of inhibiting shipments.

From a geographic perspective, mature markets generally outperformed emerging markets, with Asia Pacific excluding Japan and Latin America in particular showing weakness, though Latin America did outperform IDC's original forecast. The US posted just a slight decline but otherwise also pulled ahead of forecast in part due to Chromebook activity. Japan again posted positive growth, in part against the backdrop of tough market conditions in 2015 through the first half of 2016.

"Amid some unevenness in market trends across the regions, the global PC market has continued to trend toward stabilization," said Jay Chou, research manager, IDC Worldwide Personal Computing Device Tracker. "Despite recent issues wrought by component shortages and its effect on system prices, we expect the momentum of commercial market replacements will contribute to eventual market growth. Consumer demand will remain under pressure, although growth in areas like PC gaming and the increasingly attractive portfolio of sleek Windows-based systems will help push the consumer market to stabilize as well."

"The US PC market continues to hold, with an estimated 0.4% contraction in the second quarter of 2017," added Linn Huang, research director, Devices & Displays. "The US market remains relatively immune to currency issues in other regions. Chromebooks for K-12 continued its momentum unabated, and Apple appears to be back on track with an uncharacteristically poor 2016 in its rearview mirror."

Regional highlights

The US traditional PC market continued to hold in comparison to other regions. Pricing pressures brought on by currency weakness have not affected the aggregate product mix in the US as it has in other regions. Chromebooks remained a source of significant volume growth in the education-buying mid-quarters. Inventory preparation and deployment for government projects, particularly around Windows 10 migration, also kept commercial volumes afloat.

The EMEA traditional PC market showed further stability in the second quarter of 2017, primarily driven by the solid performance of notebook sales. An acceleration in mobility adoption was a major contributor to the positive notebook results, exceeding IDC's expectations. However, desktop sales performed in line with forecast.

The traditional PC market in the Asia Pacific excluding Japan region returned negative results this quarter, slightly below IDC's expectations. GST reform in India had an adverse impact on shipments in the country, with channel players placing cautious orders amid uncertainty in the market, while the anticipated ELCOT education tender has been postponed due to legal issues surrounding execution of the project. In China, the market is expected to return softer results, as consumer demand slowed and the industry faces high inventory levels.

The traditional PC market in Japan continued its recovery from tough conditions in 2015 and 2016, with further transition from desktop to notebook in the commercial sector, but more importantly a number of refresh projects to replace PCs bought during the last upgrade cycle four years ago.

Vendor highlights

HP retained the top spot for the second quarter in a row. The vendor hit a new high mark for market share at nearly 23%, with aggressive growth in virtually all regions.

Lenovo held the second position but shrank 5.7% globally. The vendor saw significant slowing in North America but still managed to grow its notebook business overall.

Dell took the third position, growing 3.7% on year, and continuing its positive growth in every region with strong notebook volume.

Apple kept the fourth position and grew 1.7% on year.

Asustek Computer regained the fifth position, overtaking Acer.
