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

— Warren Buffett

The Warren Buffett investment philosophy calls for a long-term investment horizon, where a decade-long holding period, or even longer, would fit right into the strategy. How would such a strategy have worked out for an investment into Delta Air Lines Inc (NYSE: DAL)? Today, we examine the outcome of a decade-long investment into the stock back in 2013.

Start date: 09/16/2013
$10,000

09/16/2013
  $19,213

09/13/2023
End date: 09/13/2023
Start price/share: $23.15
End price/share: $39.55
Starting shares: 431.97
Ending shares: 485.88
Dividends reinvested/share: $5.82
Total return: 92.17%
Average annual return: 6.75%
Starting investment: $10,000.00
Ending investment: $19,213.26

As shown above, the decade-long investment result worked out well, with an annualized rate of return of 6.75%. This would have turned a $10K investment made 10 years ago into $19,213.26 today (as of 09/13/2023). On a total return basis, that’s a result of 92.17% (something to think about: how might DAL shares perform over the next 10 years?). [These numbers were computed with the Dividend Channel DRIP Returns Calculator.]

Notice that Delta Air Lines Inc paid investors a total of $5.82/share in dividends over the 10 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 .4/share, we calculate that DAL has a current yield of approximately 1.01%. Another interesting datapoint we can examine is ‘yield on cost’ — in other words, we can express the current annualized dividend of .4 against the original $23.15/share purchase price. This works out to a yield on cost of 4.36%.

“Value investing means really asking what are the best values, and not assuming that because something looks expensive that it is, or assuming that because a stock is down in price and trades at low multiples that it is a bargain.” — Bill Miller
