Investing For Value

Tips E-25: A 1-minute summary of my fundamental analysis of Rambus Inc (NASDAQ: RMBS)     Investment Thesis Rambus has successfully transitioned toward scalable IP licensing and memory interface chips aligned with AI and data-center growth. Strong moats and financial discipline support long-term value creation, but optimistic market pricing already reflects much of this improvement. Main Business Rambus operates a focused, fabless model built on proprietary memory interface chips and high-margin silicon IP licensing. Its two core segments serve advanced computing, AI, and data-center ecosystems. Deep customer integration, enforceable patents, and long design cycles create high switching costs, supporting recurring revenues and durable competitive advantages. Growth Revenue growth has been steady, supported by acquisitions and favourable end-market tailwinds rather than aggressive organic expansion alone. AI infrastructure, DDR5 adoption, and data-center expan...

Value Investing Case Study 120-1: A fundamental analysis of Nestle (Malaysia) Berhad, where I assess whether it is a high-quality business with fading economics.    For decades, Nestlé (Malaysia) Berhad has been the gold standard of Malaysian consumer staples. Iconic brands. Stable demand. Strong dividends. But a closer look at the numbers tells a more complicated story. Over the past decade, Nestlé Malaysia has continued to grow revenue steadily and generate impressive cash flows. Returns on capital remain well above the cost of capital — a hallmark of a high-quality business. Yet beneath this resilience lies a persistent and uncomfortable trend: profits and margins have been quietly eroding. Gross profit and contribution margins have been on a long-term decline. This is not a story of bloated overheads or sloppy execution — fixed costs are tightly controlled. Instead, the pressure is coming from the top of the income statement: sustained input cost inflation, cons...

Tips E-24: A 1-minute summary of my fundamental analysis of TTM Technologies Inc. (NASDAQ: TTMI) Investment Thesis TTMI now focuses on advanced PCBs and mission-critical systems rather than commoditized consumer electronics. Despite this strategic progress, persistent cost-control issues and subpar returns on capital mean the transformation has not translated into sustainable shareholder value. Main Business The company products are used in aerospace and defense platforms, data center infrastructure, and automotive electronics. These markets feature higher reliability requirements and longer product cycles, supporting differentiation but demanding disciplined execution and cost management. Growth From 2015 to 2024, revenue grew only about 1.7% CAGR as TTMI divested consumer-facing units and shut down commoditized operations. Underlying demand improved, evidenced by 9.4% growth in 2024 when no divestitures occurred, suggesting better organic potential going forward. Profitabili...

This is Chapter 5 of my book Mastering Value Investing: Practical Strategies for Real-World Results . Go there for links to the other chapters. Most investors think diversification reduces risk. They are only half right. If diversification were the magic answer, owning 100 stocks would make you rich and safe. But in reality, many diversified portfolios quietly underperform - not because investors took too much risk, but because they misunderstood what risk actually is. This chapter challenges the comfortable myths most investors rely on. Risk is not volatility. It is not short-term price swings. Risk is permanent capital loss - and portfolio construction is one of the most underappreciated tools for preventing it. Inside this analysis, you will see why portfolio construction is not an afterthought, but a core risk-management system. Not through formulae or academic theory, but through practical decisions every investor must make. You will also see real-world examples that ...

Tips E-23: A 1-minute summary of my fundamental analysis of STMicroelectronics N.V. (NYSE: STM)      Investment Thesis STMicroelectronics operates in structurally attractive markets such as electrification, industrial automation, and edge AI, where its vertical integration and long customer design cycles support durable returns. It is a fundamentally strong semiconductor leader offering a rare combination of moat strength and valuation support.  Main Business STM’s vertically integrated model enables reliability, cost control, and customization, particularly in automotive MCUs, power semiconductors, and MEMS, where switching costs and qualification barriers are high. Growth Long-term growth is primarily organic, supported by secular demand rather than acquisition-driven expansion. From 2015 to 2024, STM grew revenue at about 7.5% CAGR. Profitability Profit growth has been amplified by margin expansion and operating leverage rather than purely higher revenues....
