“Someone’s sitting in the shade today because someone planted a tree a long time ago.”

— 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 twenty year holding period possibly?

Suppose a “buy-and-hold” investor was considering an investment into Gilead Sciences Inc (NASD: GILD) back in 1999: back then, such an investor may have been pondering this very same question. Had they answered “yes” to a full twenty year investment time horizon and then actually held for these past 20 years, here’s how that investment would have turned out.

Start date: 04/16/1999
$10,000

04/16/1999
$567,217

04/15/2019
End date: 04/15/2019
Start price/share: $1.28
End price/share: $65.43
Starting shares: 7,812.50
Ending shares: 8,671.02
Dividends reinvested/share: $8.12
Total return: 5,573.45%
Average annual return: 22.36%
Starting investment: $10,000.00
Ending investment: $567,217.73

As shown above, the twenty year investment result worked out exceptionally well, with an annualized rate of return of 22.36%. This would have turned a $10K investment made 20 years ago into $567,217.73 today (as of 04/15/2019). On a total return basis, that’s a result of 5,573.45% (something to think about: how might GILD shares perform over the next 20 years?). [These numbers were computed with the Dividend Channel DRIP Returns Calculator.]

Dividends are always an important investment factor to consider, and Gilead Sciences Inc has paid $8.12/share in dividends to shareholders over the past 20 years we looked at above. Many an investor will only invest in stocks that pay dividends, so this component of total return is always an important consideration. Automated reinvestment of dividends into additional shares of stock can be a great way for an investor to compound their returns. The above calculations are done with the assuption that dividends received over time are reinvested (the calcuations use the closing price on ex-date).

Based upon the most recent annualized dividend rate of 2.52/share, we calculate that GILD has a current yield of approximately 3.85%. Another interesting datapoint we can examine is ‘yield on cost’ — in other words, we can express the current annualized dividend of 2.52 against the original $1.28/share purchase price. This works out to a yield on cost of 300.78%.
