Broadcom vs. Navitas Semiconductor: Which AI Chip Maker Stock Is a Better Buy in 2026?

The article contrasts Broadcom (AVGO) vs. Navitas Semiconductor (NVTS): AVGO reported FY2025 revenue of ~$63.9B (+24% YoY) and net income of ~$23.1B (net margin ~36.2%) with FCF of ~$26.9B, while NVTS FY2025 revenue fell to ~$45.9M (-45% YoY) and net loss widened to ~$117.0M with negative FCF of -$44.4M. Valuation also diverges sharply—AVGO trades at ~19.7x forward P/E and 23.9x P/S vs. NVTS’s ~88.3x P/S and much higher implied forward P/E (~357x sector given). Net takeaway: AVGO is positioned as a lower-risk AI infrastructure beneficiary, whereas NVTS is framed as a high-execution-risk pivot (with TSMC’s GaN exit by mid-2027) that has not yet produced revenue growth.

Analysis

AVGO is the cleaner winner here, but not because the market is missing the AI story — because it is underestimating how much of the equity value is being driven by recurring software and networking attach, not just cyclical semiconductor units. The main second-order issue is that this business is still supply-chain constrained by TSMC, so the “quality compounder” multiple is only durable if wafer allocation stays intact and hyperscaler spend does not decelerate; that makes AVGO less bond-like than the bull case implies.

NVTS remains a financing-and-execution story disguised as a platform transition. The real risk is not just revenue slippage, but that the company burns optionality before the AI power-delivery thesis becomes monetizable; if the manufacturing migration or design-win conversion is delayed, the stock can stay trapped in a value-destructive dilution loop. GFS is the understated beneficiary if outsourced GaN capacity actually shifts, while TSM is a hidden loser if it exits a niche process and cedes future content.

The consensus is too binary: AVGO is not a no-brainer at any price, and NVTS is not automatically worthless just because trailing fundamentals are weak. Over 1-3 months the market should continue paying for visibility, so AVGO can outperform on any evidence of stable AI capex; over 6-18 months, though, the multiple likely hinges on whether AI networking growth remains above digestion levels. The falsifier for the AVGO bull is a guide-down tied to customer concentration or capex pause; for NVTS, the thesis breaks if there is no revenue inflection before the 2027 supply transition window.

Key Decisions for Investors

• Long AVGO / short NVTS as a 1-3 month quality-vs-optionalit​y relative-value trade; thesis is that capital will keep rotating toward cash-generative AI infrastructure while speculative power-semiconductor stories stay under pressure. Use a 2:1 risk/reward target and cover the short if NVTS shows credible sequential revenue acceleration or a strategic deal with hard revenue terms.
• Buy AVGO on 5-7% pullbacks into earnings or AI-capex headlines; the setup is attractive as long as the next guide does not signal demand digestion. Falsifier: a meaningful downward revision in networking or software growth, or evidence of customer concentration becoming a revenue headwind.
• Do not short AVGO outright as an AI-exposed proxy; if you want downside protection, use a put spread against a broad semis basket instead. AVGO's cash generation and buyback capacity make single-name downside harder to sustain unless the macro or customer spend picture breaks.
• Set NVTS as a watchlist-only name, not a core position, until there is proof of revenue traction from AI power-delivery wins. If you must express the view, use small downside put spreads rather than stock shorting because short-interest risk is high and the path to failure is dilution-driven rather than linear.
