Frequently asked
Is Applied Optoelectronics a high-quality business?+
Applied Optoelectronics scores 40 out of 100 on Intrinsiqq's quality score, a weighted blend of 6 metrics each scored 0 to 100, which makes it a mixed business on these measures. Recent fundamentals include a -11.3% operating margin and a -4.8% return on invested capital. The score weighs revenue and free-cash-flow growth, operating margins, return on invested capital, share-count change, and balance-sheet strength, all computed from SEC filings, not opinion. Because valuation only means something relative to quality, the full metric-by-metric breakdown is on the quality scorecard.
Is Applied Optoelectronics a good stock to buy right now?+
That depends on valuation and quality together, not either alone. you should weigh AAOI's valuation and scores 40/100 on quality (mixed). A cheap price is only a bargain if the business is durable, and a premium can be justified by genuine quality, so the two questions, "is it cheap?" and "is it good?", only make sense side by side. Read the valuation against the quality scorecard, run the DCF on your own assumptions, and decide for yourself. This is analysis from SEC filings, not investment advice.
