Warren Buffett the world's most successful investor, has doubled his stakeholding in Apple as he predicts the company will be the first firm to top a one trillion dollar valuation. Warren Buffett is known as the Sage of Omaha. Not only is he the world's most successful investor, not only is he one of the richest men in the world - indeed from thine to time his wealth even exceeds that of Bill Gates - but he has made investors who bought shares in his company, Berkshire Hathaway, and held on to them for an extended time frame, an awful of money.

But Mr Buffett does not do tech. He does do consumer goods companies with products that people feel they need, with strong balance sheets, and valuations he thinks are on the lowish side.

He is famous for his backing of Coca-Cola, and he is also one of two key shareholders in Kraft Heinz, which just failed to buy Unilever.

He is less famous as an insurance guy, who uses the cash flow insurance generates to invest in safe companies. Yet this was, however, the real key to his success.

But he is not a backer of Alphabet, Amazon, or Facebook. And until recently he was not a backer of Apple.

It is strange to think that the man who is revered as the world's greatest investor missed the investments triumphs of this century so far: the big US techs.

In Q4, the sage did buy into Apple.

But since then he has noticed that when he takes his grandkids and their friends out, they all have iPhones. He asks them what they would do without these devices, observers the stickiness of the iPhone, and hey presto, thinks 'maybe I should help me to some more of Apple'.

And so Mr Buffett, via Berkshire Hathaway, goes out and doubles his stake in Apple, taking his total stock holding to 133 million shares, worth $17 billion and accounting for around 2.5 per cent of Apple.

He now has almost as much invested in Apple as Coca-Cola.

You could be critical and ask Mr Buffett what took him so long to buy the shares? But then critisiisng Buffett's investment ability is like moaning about Mozart's musical ability, or Shakespeare's command of the English language.

And yet Apple fans, those who, probably unlike Warren Buffett, spend hours a day on their iPhone, also say that Apple is looking interesting again thanks to the opportunity of augmented reality, wearables and maybe even autonomous/electric cars.

It seems unlikely that Mr B bought into Apple because of his expectations for AR.

The fact he likes the company anyway seems to be telling us something pretty positive about Apple.
