Is Pixelworks, Inc. overvalued or undervalued?

As of 7 November 2017, the valuation grade for Pixelworks, Inc. has moved from attractive to risky, indicating a shift in perception regarding its financial health and market position. The company appears to be overvalued given its negative price-to-book value of -1.99 and an EV to EBITDA ratio of -0.58, both of which suggest significant financial distress. Additionally, the EV to Sales ratio stands at 0.48, further highlighting the challenges the company faces in generating revenue relative to its enterprise value.
In comparison to its peers, Pixelworks, Inc. has a worse EV to EBITDA ratio than companies like Intevac, Inc. (-1.4985) and GSI Technology, Inc. (-4.7369), which also reflect risky valuations. The overall sentiment is reinforced by the company's current stock price of 11.21, which is significantly above its 52-week low of 4.67, but still raises concerns given the lack of profitability metrics. While specific return data is not available, the absence of positive returns compared to the S&P 500 may suggest that the stock is not performing well in the broader market context.
