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

— Warren Buffett

The Warren Buffett investment philosophy calls for a long-term investment horizon, where a two-decade holding period, or even longer, would fit right into the strategy. How would such a strategy have worked out for an investment into Lam Research Corp (NASD: LRCX)? Today, we examine the outcome of a two-decade investment into the stock back in 1999.

Start date: 11/15/1999
$10,000

11/15/1999
$102,739

11/12/2019
End date: 11/12/2019
Start price/share: $28.71
End price/share: $270.01
Starting shares: 348.31
Ending shares: 380.22
Dividends reinvested/share: $11.97
Total return: 926.64%
Average annual return: 12.35%
Starting investment: $10,000.00
Ending investment: $102,739.78

As shown above, the two-decade investment result worked out quite well, with an annualized rate of return of 12.35%. This would have turned a $10K investment made 20 years ago into $102,739.78 today (as of 11/12/2019). On a total return basis, that’s a result of 926.64% (something to think about: how might LRCX shares perform over the next 20 years?). [These numbers were computed with the Dividend Channel DRIP Returns Calculator.]

Notice that Lam Research Corp paid investors a total of $11.97/share in dividends over the 20 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 4.6/share, we calculate that LRCX has a current yield of approximately 1.70%. Another interesting datapoint we can examine is ‘yield on cost’ — in other words, we can express the current annualized dividend of 4.6 against the original $28.71/share purchase price. This works out to a yield on cost of 5.92%.
