What's working
- The cyclical case is unusually well-evidenced: DIOD publishes its own weighted-average ASP change in MD&A, and the 2025 ASP index sits 4.6% ABOVE 2021 — the "commodity price erosion" story is just the unwind of a +28.5% shortage spike, not structural destruction. Channel inventory is below the normal 11-14wk band and still falling in $ and weeks against record POS — they are under-shipping consumption. Automotive hit a record 21% (+37% YoY), breaking a 3-year plateau at exactly 19%. Fortress balance sheet: ~$442M cash vs ~$40M debt
- The China bear case largely FAILED — China revenue is at a record (+33% YoY in Q2), DIOD manufactures in Shanghai/Wuxi with HNTE status, and all four Chinese rivals raised prices twice in 2026 (+10-20%); only Yangjie has real Western exposure and it was EU-sanctioned 4/23
Red flags
- Management admitted TWICE that it is benefiting from the Nexperia/Wingtech government seizure — a windfall that reverses
- 3 of 4 China HNTE tax approvals expire end-2026 (15%→25%) — nearest-dated risk, undiscussed
- Every named officer sold (May cluster at $96-112, above spot); zero open-market buys ever.
Watch
- ANALYZED 8/06 — first file ever. WATCH, DO NOT BUY. FV $60-85 (central ~$72) — spot is 39% ABOVE the midpoint. Q2 beat and the Q3 guide is the story: ~$510M (+30% YoY, 8% above consensus), GM 35.0%, non-GAAP EPS $1.05 (30% above consensus, 2.8x YoY)
- But: moat 2/5, through-cycle ROIC ≈ cost of capital (mgmt's own $2B target implies ~9.4%), and the recovery has ALREADY happened — Q3 guidance is 97.8% of the all-time record quarter, and all three "3-year" targets are met at run-rate two-plus years early.
- Coverage is TWO analysts who disagree by 44% ($192 Baird vs $133 Truist — and Truist CUT into a 30% EPS beat)
- Yahoo's 17.2x fwd P/E rests on a $5.85 EPS that exceeds the company's own ">$4" target; tgt $126.50 is the pre-print average. Entry $60-72.
- NO MULTIPLE TRIM — trim on strength >$110, or on any quarter where GM plateaus at 34-35% while revenue sets records → [[pitfall-multiple-trim-inverts-on-peak-cycle-cyclicals]]
📋 🔴 8/06 首次分析 — 首个文件。 观望，不要买入。 合理价值 $60-85（中枢约 $72）— 现价比中枢高 39%。 ** 第二季度超预期，而 第三季度指引才是重点：约 $510M（同比 +30%，比一致预期高 8%），毛利率 35.0%，非 GAAP 每股收益 $1.05（比一致预期高 30%，同比 2.8 倍）。 ✅ 周期性的判断有异常扎实的证据： DIOD 在 MD&A 中逐年披露自己的 加权平均售价变化，而 2025 年的售价指数比 2021 年 高出 4.6% — 所谓「大宗商品价格侵蚀」只是 +28.5% 缺货涨价的回吐，并非结构性破坏。 渠道库存 低于 11-14 周的正常区间，且在金额和周数上继续下降，同时销售终端出货创纪录 — 他们的出货量 低于实际消耗。 汽车业务创下 21% 的纪录（同比 +37%），打破了连续三年恰好停在 19% 的平台期。 资产负债表稳固：现金约 $442M，负债约 $40M。 ✅ 中国空头逻辑基本证伪 — 中国收入创下 纪录（第二季度同比 +33%），DIOD 本身就在上海/无锡 设厂生产 并享有高新技术企业税收资格，且四家中国竞争对手在 2026 年 两度提价（+10-20%）；只有扬杰科技有真正的西方市场敞口，而它已在 4/23 被欧盟制裁。 🔴 但是：护城河 2/5，穿越周期的投入资本回报率约等于资本成本（管理层自己的 $2B 目标隐含约 9.4%），而且复苏已经发生 — 第三季度指引已是 历史最高单季的 97.8%，且 三项「三年」目标全部提前两年多在年化口径上达成。 ** 🚩 管理层两次承认自己正受益于 Nexperia/闻泰科技被政府接管 — 这是会逆转的意外之财。 🚩 4 项中国高新技术企业税收批准中有 3 项在 2026 年底到期（15%→25%） — 最近在眼前、却无人讨论的风险。 🚩 每一位具名高管都在卖出（5 月集中在 $96-112，高于现价）；从未有过任何公开市场买入。 ** ⚠️ 覆盖只有两位分析师，且分歧达 44%（Baird $192 对 Truist $133 — 而且 Truist 是在每股收益超预期 30% 的情况下下调目标价）。 ⚠️ 雅虎 17.2x 的前瞻市盈率建立在 $5.85 的每股收益之上，而这已超过公司自己「>$4」的目标；目标价 $126.50 是财报前的均值。 入场 $60-72。 ** 🔴 不使用倍数式减持 — 在 >$110 的强势中减持，或在任何一个「营收创纪录而毛利率却停在 34-35%」的季度减持 → [[pitfall-multiple-trim-inverts-on-peak-cycle-cyclicals]]。 未持有；对一个半导体仓位只有 INTC/QCOM/AVGO 的组合而言可以起到分散作用。

Competitors竞争对手
Why customers stay客户为什么留下
Diodes wins by being a low-cost, reliable maker of simple, high-volume parts, not by chasing the most advanced chip designs. Making basic parts well, cheaply, and in huge numbers is hard for bigger rivals to match at the low end. Its smaller size also lets it move fast and adapt to customer needs more quickly than larger competitors.Diodes Incorporated 凭借低成本、可靠地大批量制造简单元件取胜，而不是追逐最先进的芯片设计。把基础元件做好、做便宜、并大量生产，是大型竞争对手在低端市场难以匹敌的能力。较小的公司规模也让它能比大型竞争对手更快地响应客户需求。
