“When we own portions of outstanding businesses with outstanding managements, our favorite holding period is forever.”
— Warren Buffett
A long holding period can reveal far more about a stock than short-term price swings ever will. In the case of Flex Ltd (NASD: FLEX), a hypothetical investment made in 2006 produced a strong 20-year return, illustrating how compounding in an operating business can create substantial shareholder value over time.
Flex is best known as a large global manufacturing and supply chain solutions company, serving customers across industries such as electronics, health solutions, automotive, industrial, and communications. That business mix means the stock has historically been influenced not only by company execution, but also by broader trends in global production, customer demand, margins, and capital allocation.
Flex 20-Year Return From 2006 to 2026
Using the figures below, a $10,000 investment in Flex on 09/25/2006 would have grown to $119,541.48 by 09/24/2026. Because the company did not contribute to total return through dividends in this calculation, the result reflects share price appreciation rather than income reinvestment.
| Start date: | 09/25/2006 |
|
|||
| End date: | 09/24/2026 | ||||
| Start price/share: | $9.41 | ||||
| End price/share: | $112.40 | ||||
| Starting shares: | 1,062.70 | ||||
| Ending shares: | 1,062.70 | ||||
| Dividends reinvested/share: | $0.00 | ||||
| Total return: | 1,094.47% | ||||
| Average annual return: | 13.20% | ||||
| Starting investment: | $10,000.00 | ||||
| Ending investment: | $119,541.48 | ||||
On these assumptions, the investment generated a total return of 1,094.47%, equal to a 13.20% average annual return over the full 20-year period. That is a notable outcome for a business tied to large-scale manufacturing, where margins can be cyclical and investor sentiment often shifts with macroeconomic conditions.
What Drove the Long-Term Gain?
The most important point in this Flex stock return analysis is that the gain came from capital appreciation, not dividend income. With dividends reinvested per share listed at $0.00, the entire increase in ending value was driven by the stock price rising from $9.41 to $112.40.
That distinction matters. Companies that do not rely on dividends to deliver shareholder returns must create value through earnings growth, margin improvement, stronger free cash flow generation, disciplined use of capital, or some combination of those factors. In long-duration holdings, stock performance tends to follow business performance more closely than short-term headlines.
A Quick Interpretation of the Numbers
For reference:
- $10,000 invested in Flex in September 2006 became $119,541.48 by September 2026.
- The position value increased by more than 11 times over the period.
- The share count did not change because no dividends were reinvested in this scenario.
- The annualized return of 13.20% shows how sustained compounding can materially expand wealth over long periods.
Why Long-Term Return Analysis Matters
Looking at a 20-year holding period can help separate durable wealth creation from temporary price momentum. A stock can experience sharp drawdowns, valuation resets, and cyclical slowdowns while still delivering an attractive long-run result if the underlying business compounds over time.
That is especially relevant for companies such as Flex, where investor expectations can fluctuate with supply chains, customer concentration, product mix, and global manufacturing demand. Over multi-year periods, however, what tends to matter most is whether the company expands its economic value and converts that progress into per-share gains.

One additional observation is worth keeping in mind: a strong historical return does not explain the path taken to achieve it. Over a 20-year span, investors typically endure market stress, sector rotations, earnings volatility, and shifts in valuation multiples. Long-term results are often shaped as much by the ability to stay invested through those periods as by the original stock selection.
