I dont know about you, but I spend quite a bit of my time as an investor trying to figure out what certain companies actually do.
For example, a colleague told me Seaenergy might be a canny buy.
It turns out that the exciting thing about Seaenergy an AIM-traded small cap is its imaging technology, R2S, which enables oil-rig operators to go on virtual tours of their rigs, rather than having to helicopter staff across the North Sea.
It sounds like a good idea, but its not something I have anything experience of.
It might be a good investment, but Im still trying to get my head around the business potential.
A Woodford weirdo
Heres another example Neil Woodfords recent investment in RM2 International.
(RM2, R2S I dont blame you if you expect R2-D2 from Star Wars to be next to join the party!)
Despite the odd name, I wanted to discover why the famous fund manager had invested in a business that had only recently joined the market and pays no dividend.
It turns out RM2 has invented a revolutionary kind of pallet, BLOCKPal, that offers customers stronger, lighter and longer-lasting pallets.
Enthusiasts claim such pallets could replace many of the 12 billion or so wooden and plastic pallets used to transport goods around the world.
RM2 only has a 250 million market capitalisation, so the potential rewards for early shareholders could clearly be vast.
But what do I know about the pallet industry?
The lure of the obscure
I dont mean to imply its futile or boring to research new companies in unknown industries.
On the contrary, doing that is one of the major attractions of investing for me.
Also, Im obviously not the only person who doesnt know their R2Ss from their RM2s. Making an extra effort to dig into these more obscure opportunities might well enable you to get in ahead of the crowd.
On the other hand, it might lead you to buy shares in a small, over-hyped company that you dont really understand, with potentially disastrous results.
A short search for a winner
Happily, you dont need to root about in the obscure corners of the stock market to find great growth shares.
On the contrary, if youre good at identifying big changes in everyday life, you might find them at your fingertips.
Im thinking of US search engine giant Google.
This month happens to be the tenth anniversary of Google joining the NASDAQ stock market in the US.
Like many people back in 2004, I already used Google every day.
Indeed, many times a day.
I also knew about its growing advertising business, partly because of my day job but also because as an Internet user I saw Google ads popping up everywhere including in my Gmail account, which I got into early, too.
Yet despite my familiarity with Google, I couldnt get my head around its $27 billion valuation on flotation.
Ten years on, Google now has a market cap of $400 billion.
Thats nearly a 15-bagger for those who had more foresight than me.
Everybodys favourite 40-bagger
Another great example of an obvious company that was going places is Apple.
Ive been an Apple fanboy for decades.
Ive only ever bought Macintosh computers, and I was an early adopter of the iPod, iPhone and iPad.
When I was a journalist in the technology industry, I often wrote about how iTunes and the like would render CD collections obsolete.
My friends were all buying Apple products, too.
Yet I didnt buy Apple shares in 2001 when the iPod came out, nor in 2007 when the iPhone arrived, nor on the debut of the iPad in 2010.
Perhaps it always seemed a bit obvious?
Over the past ten years, Apple has been a 40-bagger for more sensible investors who spotted and invested in this wildly successful company.
The right stuff
Turning literally closer to home, what about Rightmove?
Some people may still buy homes without using the Internet, but I dont know them.
In fact, I know plenty of people who browse the property listings on Rightmove for fun.
When it floated on the London Stock Exchange in 2006, I knew Rightmove, I used Rightmove, and my friends used Rightmove.
The shares then cost 3.35.
Today they cost 25, making the company a seven-bagger for early investors. And thats ignoring dividends.
Buy what youre buying
Was it a no-brainer that Google, Apple and Rightmoves businesses would grow so far, so fast, and thus deliver these extraordinary returns?
I dont think so. Hindsight is dangerously seductively.
The point is not that identifying multibaggers is easy, but rather that to find them you dont need to hunt for companies youve never heard of in industries you dont understand.
