“I buy on the assumption that they could close the market the next day and not reopen it for five 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 five year holding period possibly?

Suppose a “buy-and-hold” investor was considering an investment into General Mills Inc (NYSE: GIS) back in 2019: back then, such an investor may have been pondering this very same question. Had they answered “yes” to a full five year investment time horizon and then actually held for these past 5 years, here’s how that investment would have turned out.

Start date: 08/05/2019
$10,000

08/05/2019
  $15,439

08/02/2024
End date: 08/02/2024
Start price/share: $52.81
End price/share: $69.28
Starting shares: 189.36
Ending shares: 222.84
Dividends reinvested/share: $10.65
Total return: 54.39%
Average annual return: 9.08%
Starting investment: $10,000.00
Ending investment: $15,439.11

As shown above, the five year investment result worked out well, with an annualized rate of return of 9.08%. This would have turned a $10K investment made 5 years ago into $15,439.11 today (as of 08/02/2024). On a total return basis, that’s a result of 54.39% (something to think about: how might GIS shares perform over the next 5 years?). [These numbers were computed with the Dividend Channel DRIP Returns Calculator.]

Notice that General Mills Inc paid investors a total of $10.65/share in dividends over the 5 holding period, marking a second component of the total return beyond share price change alone. Much like watering a tree, reinvesting dividends can help an investment to grow over time — for the above calculations we assume dividend reinvestment (and for this exercise the closing price on ex-date is used for the reinvestment of a given dividend).

Based upon the most recent annualized dividend rate of 2.4/share, we calculate that GIS has a current yield of approximately 3.46%. Another interesting datapoint we can examine is ‘yield on cost’ — in other words, we can express the current annualized dividend of 2.4 against the original $52.81/share purchase price. This works out to a yield on cost of 6.55%.

Another great investment quote to think about:
“The idea that a bell rings to signal when to get into or out of the stock market is simply not credible. After nearly fifty years in this business, I don’t know anybody who has done it successfully and consistently.” — Jack Bogle
