NEW YORK (

TheStreet

) --

Alcoa

(AA) - Get Report

has become the traditional lead-off hitter to earnings season, and the company got things off to

a strong start

, delivering an unexpected profit of 2 cents a share on revenue of $5.8 billion.

Excluding special items, Alcoa earned 11 cents a share.

The numbers were a sort of razzie for the

Dow Jones Industrial Average

, which recently dropped Alcoa (along with

Hewlett-Packard

(HPQ) - Get Report

and

Bank of America

(BAC) - Get Report

) in favor of sexier offerings

Nike

(NKE) - Get Report

,

Visa

(V) - Get Report

and

Goldman Sachs

(GS) - Get Report

.

But the news was significant in another way, demonstrating that old-line, basic-material companies can find ways to succeed by finding new markets. In Alcoa's case, this can be summed up in one word: transportation. Aluminum is lighter than steel, and Alcoa has increased its penetration in both car and plane manufacturing.

In its conference call, Alcoa executives took the time to attack the London Mercantile Exchange, or LME, for changes to its warehousing policy it said distorted the market.

This is seen as an opportunity by the

CME Group

(CME) - Get Report

, which plans to offer an aluminum futures contract soon. Alcoa wants the LME to start reporting how traders are using its warehouses, as is required in the U.S.

The price manipulation made possible by LME rules actually made it into popular culture this last quarter when John Oliver of

The Daily Show

ran

a segment

on

Goldman Sachs

's

(GS) - Get Report

use of it.

Alcoa's place at the intersection of international price-fixing, high-tech manufacturing and popular culture may seem trivial, but it's not. Like a classic lead-off hitter, the results for this basic materials company tend to set the table for the rest of earnings season.

Basic-material stocks have actually done a good job of mirroring the broader

S&P 500

index this year. They are very similar. They're down about 1.28% while the market as a whole is up only less than 1%, and the pattern of movements in both has seldom diverged. They may not seem sexy, but they're called basic for a reason.

Because Alcoa was dropped from the Dow, it may not be seen as a lead-off hitter by all traders, who will be waiting instead for

JPMorgan Chase

(JPM) - Get Report

to report on Friday.

But the performance of metals, as compared with the overall market, shows they're still relevant. (The Dow rotates stocks into its index so that the index will always trend upward: Only

GE

(GE) - Get Report

remains from the original list of 12 offered by Charles Dow in 1896.)

So what does the Alcoa result mean for Alcoa and for the general market? Here is my view.

For one thing, it means that the U.S.'s cost advantage in energy, especially natural gas, remains a powerful driver for economic growth.

It means energy efficiency, as a design goal, remains an important trend. Lighter materials, like aluminum, have a continuing advantage over heavier materials like steel. Since efficiency can help pay for new goods, and energy prices remain high, that's also bullish.

In short there's a tailwind behind U.S. business that exists outside questions about government policy. Many American businesses that were becoming noncompetitive and irrelevant, like Alcoa, are now profitable and relevant again.

To use an October analogy, it's a solid single to left. We'll see Friday whether JPMorgan Chase can follow up and get traders cheering.
