Same PEG ratio figures as the table above, plotted for a direct read. Bold = held in this book.

Market cap, P/E, PEG, EV/EBITDA, and capex sourced via public filings and financial-data aggregators (GuruFocus, StockAnalysis, company earnings releases), as of August 2026. PEG ratio sourced primarily from GuruFocus where available; different providers use different growth-rate assumptions, so figures elsewhere for the same stock can vary by several multiples.

Why Broadcom over Marvell and Qualcomm

Broadcom now carries the lowest PEG of the three (0.47), with Marvell next (1.12) and Qualcomm the most expensive on this growth-adjusted basis (7.58) — a reversal from when Marvell briefly looked cheaper. I hold Broadcom specifically because its custom-silicon business pairs with a large, sticky infrastructure-software franchise built through acquisitions — a more diversified earnings base than a pure custom-chip designer, which matters given how lumpy hyperscaler custom-silicon orders can be. Marvell remains a legitimate name to watch on the same custom-silicon thesis. Qualcomm is fundamentally a different bet on mobile and connectivity chips rather than AI-accelerator custom silicon, which is why it isn't part of this comparison's core thesis regardless of where its multiple sits in a given quarter.
