Apple is probably the best business competitor in the world. And when you win, eventually you will have to deal with anti-trust accusations, much as Microsoft dealt with in operating systems in the 1990s. Anti-trust actions are famously difficult to prove, but I think in the coming years you'll hear more about it with Apple because it controls huge amounts of business.

I wrote about this a couple weeks back on Investor Uprising, but I thought it would be good to summarize what about Apple makes it so dominant in the market... for, well, everything.

Apple, after all, is not just growing in one segment. It's actually taking huge chunks of profit  out of entire industries.

Apple also enjoys fatter profit margins because of its vertically integrated model -- which has come at the expense of telecom providers who must subsidize customers' never-ending thirst for iPhones and iPads. It also allows Apple to build in excess profits into components such as chips, because it can charge a premium.

 Let's just look at some facts about Apple's dominance.

• Apple has single-handedly boosted the stock market. Bloomberg tells us that Apple alone has accounted for 8% of the S&P 500's rise since the 2009 bottom. And Barclay's analysts recently pointed out that Apple has had an outsized influence on the markets, accounting for 15% of the growth in all of the S&P's rise this year. They estimate Apple contributed four times its weight to the index by having outsized profits. So maybe the government should launch an inquiry into Apple controlling the stock market.

   

• Apple's profits account for most of recent profit growth. According to FactSet research, if you subtract Apple's earnings from the market in the fourth quarter 2011, profit growth for all of the S&P 500 was -1.6%. With Apple profit growth added back in, overall profit growth was flat. That's right folks -- without Apple, there would be no growth in profits. It alone accounted for all of the profit growth in S&P 500 in the last quarter last year, and FactSet expects Apple to the be the largest source of earnings growth in Q1 2012.

   

• Apple leverages major telecoms through subsidies. The retail price on a new iPhone can be as high as $600. A telecom carrier will sell it to you for $199. Think about Apple's core sales channel: telecom operators. Apple has so much leverage that it can largely dictate the terms in these relationships so that telecom operators subsidize sales of its devices.

  In extreme cases, such as the deal with Sprint, the subsidy is a simple transfer of wealth from carrier to Apple. Sprint tagged its subsidy expense at $1.7 billion, up from $1.2 billion a year earlier. Some analysts predict this can't last, that Apple has to give back more of its profits to carriers. But Apple's immense leverage means it can dictate the terms.

• Apple is taking over all of retail electronics. Blog site Zero Hedge recently calculated that Apple's market capitalization now surpasses that of the entire retail industry. How is this possible? Well, as i-devices have added functionality such as music, communications, and video, they have eliminated entire segments of the industry. Maybe this is contributing to Sony's recent woes. Once you have an iPad, you need a portable DVD player?

   

• Apple's winning the smartphone profit battle. Though it's having a see-saw battle with the Android-powered mobile phones and can't quite gain majority market share, Apple recently gained some share back and now represents 43% of the smartphone market to Android's 53%, according to the NPD group. But more importantly, Apple makes more money in this market. Keep in mind that Google does not profit on Android directly because it gives its operating system away for free to phone manufacturers, whereas Apple controls its own manufacturing from the Operating System (OS) to the memory chips. Apple's model results in more profit, because it can charge more for all of the components in its product, including the OS. Even though it's not winning top market share, Apple is winning on profitability.

   

• Apple controls digital music. Remember the music industry? Apple's influence and control of digital music is still growing. It now accounts for 69% of all digital music sales. Amazon is a distant second with 8 percent, according to the NPD group. Apple's growth in digital sales means it now serves up about 25% of all music units, which includes physical units (even though Apple sells no physical music units), according to the NPD group. That's up from 14% in 2007.

I think that Apple's growing power and dominance in a number of industries is likely to be a topic for trade regulators for some time. The regulators have plenty of areas to mine, most notably Apple's control of the relationships in the telecommunications sales channel.

Will they make any progress? It may take years and years, but eventually you may see more legal action against Apple in the realm of anti-trust actions.

Don't get me wrong: I think Apple earned the control of markets that it has. It has better products, and it's a better company. We're also not crying because Apple is one of the leading components of our IU25 Index, which is up 35% in one year.

But it's not just about e-books. Apple's immense control now extends to the broad range of the entire business universe.
