I took a look recently at AstraZeneca, and was impressed to see an overall trebling in value over the past 10 years if all dividends were reinvested.
The FTSE 100‘s other big pharmaceuticals company, GlaxoSmithKline (LSE: GSK) (NYSE: GSK.US) hasn’t been doing quite so well — for one thing, it hasn’t had its shares boosted by takeover fever.
A 20% gain?
If you’d invested £10,000 in GlaxoSmithKline shares 10 years ago, you’d have been paying around 1,191p apiece — and at that price you could have bagged 839 shares (ignoring dealing costs).
Now, the share price has only gained 21.5% over the period, and your ten grand would have grown to £12,149. While that might have matched cash in a savings account, we really expect better from investing in shares.
But that doesn’t include dividends, so what would those have added?
Rising dividends
GlaxoSmithKline has actually been paying pretty decent dividends, starting the period offering yields of around 3.5%. But that started ramping up in 2007 as the share price fell a little, reaching 5% by 2009 — and yields have remained close to that level since.
One thing that does mean is that dividends alone would have easily been enough to beat cash sitting in the bank, without any share price gain!
Earnings per share (EPS) can be a little volatile, but even when EPS didn’t cover the dividend in 2010, Glaxo maintained the cash payment from its own resources — and EPS was back up to normal the next year.
Another five grand!
In total, GlaxoSmithKline would have paid you an extra £4,971 in dividends, taking your total to £17,120 — and a 71% rise is starting to look reasonable.
But what if, instead of taking and spending your cash handout each year, you had reinvested it in more Glaxo shares?
Before we look at that, let me mention a thing called pound cost averaging — it’s a fancy term that just means you’ll get more shares for the same money over a period when the price dips and recovers than if it had remained flat.
For Glaxo, what that means is that you’d have added just 24 new shares at the end of 2004 when the price was around 1,440p, but by 2007 when it had dropped to 1,210p you’d have scooped up 40 of them.
A decent result
Anyway, with dividends reinvested, you’d be ending the decade with £18,594 — and an 85.5% gain is really nothing to be sniffed at, especially for a share that has actually lagged the FTSE a little over the period (but with better than average dividend yields).
