The investigation concerns whether Applied Optoelectronics and certain of its officers and/or directors have engaged in securities fraud or other unlawful business practices.

On September 27, 2018, a Loop Capital Markets analyst downgraded Applied Optoelectronics' stock, reporting that the Company was experiencing product quality issues with certain transceivers in which its lasers fail after thousands of hours of operation. The analyst also lowered gross margin and revenue expectations, citing product quality issues that suggested that Applied Optoelectronics would begin procuring lasers externally through 2019. On this news, Applied Optoelectronics' stock price fell $2.98 per share, or more than 9%, to close at $28.36 per share on September 27, 2017.

Then, on September 28, 2018, Applied Optoelectronics cut its revenue guidance for the third quarter of 2018, stating that it had identified an issue with its lasers that had led the Company to temporarily suspend shipments of certain transceivers. On this news, Applied Optoelectronics' stock price fell $3.70 per share, or more than 13%, to close at $24.66 per share on September 28, 2018.
