Data I/O Corporation (NASDAQ:DAIO) specializes in creating programming and security systems for electronic devices. The company operates in the competitive electronics manufacturing industry. Its performance is often measured against peers to understand its financial health and ability to create value from the money it invests in its operations.

A key way to measure a company's efficiency is by comparing its Return on Invested Capital (ROIC) to its Weighted Average Cost of Capital (WACC). ROIC shows how much profit a company makes from its investments. WACC is the average cost the company pays for its funding. A healthy company’s ROIC should be higher than its WACC.

Data I/O currently shows a challenging financial picture. The company has a negative ROIC of -58.76%, while its WACC is 10.40%. This means Data I/O is not generating returns to cover its cost of capital. Instead, the large negative figure indicates that it is losing a significant amount on the capital it has invested.

When compared to its peers, the data shows a difficult environment for many. Companies like Schmitt Industries, Inc. (NYSEAMERICAN:SMIT) and CSP Inc. (NASDAQ:CSPI) also have negative ROICs of -55.91% and -2.90%, respectively. This suggests that many firms in this sector are struggling to generate profits from their invested capital.

However, Nortech Systems Incorporated (NASDAQ:NSYS) stands out in this group. It is the only company with a positive ROIC of 3.08%. While this is still below its WACC of 5.28%, its ability to generate a positive return shows stronger capital management and operational efficiency relative to its peers.
