It may have surprised traders and impressed the Apple Inc (NASDAQ:APPL) board but was Warren Buffett's acquisition of $1.1bn-worth of the IT company's shares such a wow moment?
On Monday, news of the Friday SEC filing certainly helped push the Nasdaq and S&P 500 tickers higher, and there can be no doubt that for those who have started to doubt Apple's longevity post-Steve Jobs, it came as a huge tonic and boost of confidence in the Cupertino, Calif. company.
But some IT boffins are starting to see a running theme in the way Warren Buffett's stock-buying vehicle Berkshire Hathaway hoovered up the stocks in Apple.
Looking back, it could be cruel to quote what Buffett told his shareholders 17 years ago. But the ethos is one that has stuck in the minds of traders even if its spokesman has, clearly, moved on.
In 1999, Buffett was worried that high-tech is also fast-tech. It changes too quickly that it is hard to back a company, before it dies off or gets taken over or its ideas adapted by someone with more guts.
Buffett has never liked that. He likes track record and he likes to be able to use that to predict the income stream for the years ahead. Tech, one of the most disruptive industries, has not lent itself to that easily, even if he's bought on the idea that IT is changing our world.
On Monday, Buffett took a stride into Apple territory and also upped his stakes in IBM (NYSE:IBM).
But it wasn't Buffett directly who did all this. It was Berkshire portfolio managers Todd Combs and Ted Weschler, who make many of the firm's smaller moves of $1 billion or less.
Back in 1999 Buffett was looking at an Apple that was still recovering from its 1990s managerial errors and Jobs was back to stamp his authority on the ailing business. The sexier design desktops and iPods were only just emerging and it was eight years before the iPhone became popular.
Whether or not he's impressed with Apple's incumbent CEO Tim Cook, these days Buffett can see Apple's potential, and no doubt sanctioned the actions of his portfolio managers to proceed to buy the company's stock.
While Apple rebranded in 2007 to become Apple Inc and underscore its foray into consumer products, not only office and school computers, so IBM has seized the initiative to hone the "Internet of Things", going head-to-head with Samsung's "Smart Things" crusade. Both the US and South Korean companies are trying to get the internet to operate everything for us at the touch of a smartphone button such as our water boiler, fridge, or when the lights go on in the house.
Buffett has read the share price of Apple like he would any stock before jumping in. Apple shares fell from $112 in mid-April down to $90 last Thursday before be bought stock.
In fact, Apple stock has been falling for a year from a peak of $132 in mid-May 2015. Buffett obviously thinks they are currently a bargain.
