“Only buy something that you’d be perfectly happy to hold if the market shut down for 10 years.”

— Warren Buffett

Investors can learn a lot from Warren Buffett, whose above quote teaches the importance of thinking about investment time horizon, and asking ourselves before buying any given stock: can we envision holding onto it for years — even a ten year holding period possibly?

Suppose a “buy-and-hold” investor was considering an investment into Broadcom Inc (NASD: AVGO) back in 2010: back then, such an investor may have been pondering this very same question. Had they answered “yes” to a full ten year investment time horizon and then actually held for these past 10 years, here’s how that investment would have turned out.

Start date: 10/18/2010


End date: 10/15/2020
Start price/share: $22.74
End price/share: $379.93
Starting shares: 439.75
Ending shares: 545.45
Dividends reinvested/share: $39.26
Total return: 1,972.33%
Average annual return: 35.41%
Starting investment: $10,000.00
Ending investment: $207,256.13

As we can see, the ten year investment result worked out exceptionally well, with an annualized rate of return of 35.41%. This would have turned a $10K investment made 10 years ago into $207,256.13 today (as of 10/15/2020). On a total return basis, that’s a result of 1,972.33% (something to think about: how might AVGO shares perform over the next 10 years?). [These numbers were computed with the Dividend Channel DRIP Returns Calculator.]

Many investors out there refuse to own any stock that lacks a dividend; in the case of Broadcom Inc , investors have received $39.26/share in dividends these past 10 years examined in the exercise above. This means total return was driven not just by share price, but also by the dividends received (and what the investor did with those dividends). For this exercise, what we’ve done with the dividends is to assume they are reinvestted — i.e. used to purchase additional shares (the calculations use closing price on ex-date).

Based upon the most recent annualized dividend rate of 13/share, we calculate that AVGO has a current yield of approximately 3.42%. Another interesting datapoint we can examine is ‘yield on cost’ — in other words, we can express the current annualized dividend of 13 against the original $22.74/share purchase price. This works out to a yield on cost of 15.04%.
