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

— Warren Buffett

The above quote from Warren Buffett is timeless, and brings into focus the choice about time horizon that any investor should think about before buying a stock they are considering. Behind every stock is an actual business; what will that business look like over a ten year period?

Today, let’s look backwards in time to 2010, and take a look at what happened to investors who asked that very question about Berkley Corp (NYSE: WRB), by taking a look at the investment outcome over a ten year holding period.

Start date: 01/11/2010
$10,000

01/11/2010
$50,913

01/08/2020
End date: 01/08/2020
Start price/share: $16.40
End price/share: $68.17
Starting shares: 609.76
Ending shares: 746.76
Dividends reinvested/share: $7.93
Total return: 409.07%
Average annual return: 17.68%
Starting investment: $10,000.00
Ending investment: $50,913.49

As we can see, the ten year investment result worked out exceptionally well, with an annualized rate of return of 17.68%. This would have turned a $10K investment made 10 years ago into $50,913.49 today (as of 01/08/2020). On a total return basis, that’s a result of 409.07% (something to think about: how might WRB shares perform over the next 10 years?). [These numbers were computed with the Dividend Channel DRIP Returns Calculator.]

Notice that Berkley Corp paid investors a total of $7.93/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 .44/share, we calculate that WRB has a current yield of approximately 0.65%. Another interesting datapoint we can examine is ‘yield on cost’ — in other words, we can express the current annualized dividend of .44 against the original $16.40/share purchase price. This works out to a yield on cost of 3.96%.

Here’s one more great investment quote before you go:
“Unless you can watch your stock holding decline by 50% without becoming panic-stricken, you should not be in the stock market.” — Warren Buffett
