“When we own portions of outstanding businesses with outstanding managements, our favorite holding period is forever.”
— Warren Buffett
A long-term investment in Lam Research Corp can serve as a striking example of how compounding works in semiconductor equipment stocks when strong business performance is paired with time. Had $10,000 been invested in shares of Lam Research Corp (NASD: LRCX) on 09/15/2006 and held through 09/14/2026 with dividends reinvested, that position would have grown to $773,321.56.
That result reflects a total return of 7,638.19% and an average annual return of 24.27%. The magnitude of the gain underscores a central feature of equity investing: over multi-decade periods, the combination of price appreciation and dividend reinvestment can produce outcomes that look disproportionate to the original capital committed.

What Drove Lam Research’s Long-Term Return?
Lam Research is a semiconductor equipment company, and that industry has historically combined powerful secular growth with pronounced cyclicality. Demand for wafer fabrication equipment rises and falls with semiconductor capital spending, memory pricing, logic investment cycles, and broader technology demand. Over long stretches, however, the growth of semiconductor content across computing, communications, industrial systems, and consumer electronics has created a favorable backdrop for leading equipment suppliers.
For LRCX, the outsized return over the period reflects more than a simple rebound in valuation. It points to a business that participated in a major expansion of global chip manufacturing capacity, while also returning capital to shareholders through dividends. Companies tied to enabling technologies can generate exceptional long-run shareholder returns when industry growth persists across multiple product cycles.
The Role of Dividend Reinvestment
Dividend reinvestment contributed meaningfully to the end result. Over the period shown above, Lam Research paid $6.11 per share in cumulative dividends that were assumed to be reinvested on the ex-dividend date at the closing price. That process increased the share count from 2,403.85 to 2,829.42 shares.
This is an important distinction when evaluating long-term stock performance. Price return shows how much the share price appreciated. Total return captures the full effect of both price appreciation and cash distributions, including the incremental shares accumulated through reinvestment. Over decades, even a modest dividend yield can become a material source of additional compounding.
Current Yield and Yield on Cost
Based on the most recent annualized dividend rate of $1.32 per share, LRCX has a current yield of approximately 0.48% using the ending share price of $273.49.
Another useful measure is yield on cost, which compares the current annualized dividend to the original purchase price. Using the initial share price of $4.16, the current $1.32 annualized dividend implies a yield on cost of 31.73%.
That figure is not the same as current market yield, and it should not be used as a valuation measure. Its value is descriptive: it illustrates how a growing dividend can transform the income profile of a successful long-term holding. In cases where the underlying business compounds for many years, the income generated relative to the original cost basis can become substantial.
Key Takeaways From the LRCX Example
- A $10,000 investment in Lam Research in 2006 grew to $773,321.56 by 09/14/2026, assuming dividend reinvestment.
- The investment produced a total return of 7,638.19% and an annualized return of 24.27%.
- Reinvested dividends increased the share count from 2,403.85 to 2,829.42 shares.
- The example highlights the difference between short-term volatility and long-term compounding in a high-quality cyclical business.
Why This Matters for Long-Term Stock Analysis
The Lam Research case is a useful reminder that exceptional long-term stock returns often come from businesses operating in economically important segments of the market, not merely from stocks that appear inexpensive at a single point in time. In capital-intensive technology industries, patience can be rewarded when a company maintains relevance across successive investment cycles.
It also shows why total return analysis matters. Looking only at the change from $4.16 to $273.49 understates the full outcome, because it excludes the additional shares accumulated through reinvested dividends. For any multi-year or multi-decade holding period, total return is generally the more complete measure of what shareholders actually earned.
