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

— Warren Buffett

The wisdom of Warren Buffett reflects a value-based philosophy about investing that says investors are buying shares in a business, and encourages strategic thinking about investment time horizon. Before placing a buy order for a stock, a great question we can ask is whether we would still be comfortable making the investment if we couldn’t sell it for many years?

A “buy-and-hold” approach may call for a time horizon that spans a long period of time — maybe even lasting for a decade-long holding period. Suppose such a “buy-and-hold” investor had looked into buying shares of Boston Scientific Corp. (NYSE: BSX) back in 2015. Let’s take a look at how such an investment would have worked out for that buy-and-hold investor:

Start date: 05/06/2015
$10,000

05/06/2015
  $60,244

05/05/2025
End date: 05/05/2025
Start price/share: $17.30
End price/share: $104.24
Starting shares: 578.03
Ending shares: 578.03
Dividends reinvested/share: $0.00
Total return: 502.54%
Average annual return: 19.66%
Starting investment: $10,000.00
Ending investment: $60,244.46

As shown above, the decade-long investment result worked out exceptionally well, with an annualized rate of return of 19.66%. This would have turned a $10K investment made 10 years ago into $60,244.46 today (as of 05/05/2025). On a total return basis, that’s a result of 502.54% (something to think about: how might BSX shares perform over the next 10 years?). [These numbers were computed with the Dividend Channel DRIP Returns Calculator.]

Another great investment quote to think about:
“You’ve got to be careful if you don’t know where you’re going, ’cause you might not get there.” — Yogi Berra
