A slowdown for Apple suppliers isn’t necessarily bad news for Apple.

There was a lot of investor angst ahead of Apple's (AAPL 1.62%) quarterly report on May 1. Analyst estimates and Apple component supplier reports suggested that iPhone demand was waning.

That speculation negatively affected the stocks of many semiconductor companies as well as Apple.

While the quarter did show signs that the iPhone business is aging, it was also proof that betting against the tech giant doesn't make sense.

What's good for the goose isn't always good for the gander

The reason has to do with an oft-forgotten financial situation: monopsony. Celebrating the good day I had following Apple's report, I went to a trivia night at a favorite taphouse where I was reminded of the term (go figure). While a monopoly is a situation in which a market has only one seller of a good or service, a monopsony is a market where there is only one buyer.

Just as a monopoly gives a company power over what it can charge customers, a monopsony can give a company the power to dictate prices it pays for product. That can have an impact on the price to produce a final good and provide a big boost to bottom-line profitability.

In today's world, pure monopolies are hard to find; the same is true with pure monopsonies. As for our case in point, Apple isn't the only smartphone maker out there. Nevertheless, Apple is a leader among just a few other tech companies that sell smartphones, giving it a lot of control over suppliers -- especially chip makers. There are many people out there who chalk up double-digit percentages of revenue attributable to the iPhone. As a result, fortunes have been made when small Apple suppliers leverage that relationship to grow into other markets (think Skyworks Solutions, for example). Even more investments have been broken, though, when a supplier's relationship is given the ax (who remembers InvenSense?).

What does that mean for Apple investors?

Trying to judge the health of Apple's bread-and-butter business from the fate of other companies can be risky. Just because iPhone sales aren't providing the boost to chip makers like they used to doesn't mean that the company's moneymaker segment is in trouble. Apple can wield a great deal of control over its supply to increase final pricing of its flagship product with innovative features, helping offset a slowdown in the number of units sold. In the current fiscal year, the pricey iPhone X is a testament to that, helping give revenue a big boost with its premium capabilities.

Even though iPhone sales are off all-time annual records set in 2015, Apple is still driving revenues higher and thus growing profitability for shareholders. Granted, there are new products and services like the Apple Watch and Apple Music helping out, but to date the iPhone still makes up two-thirds of the total business.

The smartphone industry is mature, but it's a monopsonistic one that favors the tech giants making the phones. Trying to frontrun Apple based on what its iPhone suppliers are experiencing is a fool's errand.

This last quarter is proof of that as the company continues to leverage its powerful device business to return value to shareholders.
