When a company delivers bad news but the stock doesn't go down, it could be a sign of a bottom (though not a guarantee). This may be the case with Applied Materials (AMAT -2.79%), the largest semiconductor equipment manufacturer in the world.

Applied released its fiscal fourth-quarter earnings report in mid-November, beating analysts' revenue expectations and meeting their expectations for earnings per share. The company guided for Q1 revenue that was lower than what analysts were expecting, but the stock rose in trading the next day. 

Applied's stock, like the entire semiconductor sector, has had a bruising 2018. Its price-to-earnings ratio has fallen from 23 to 10, and its dividend yield has increased to 2.26% as the stock price has dropped by about 30% year to date as of this writing.

Is Applied a bargain, or are there more tough times ahead?

The Jinhua equipment ban hurt Applied more than others 

The main reason for the guidance miss is Applied's relatively large exposure to Chinese firm Fujian Jinhua Integrated Circuit Co., Ltd. Fujian is on the receiving end of an equipment ban from the U.S. Commerce and Justice Departments issued in early November. The ban -- preventing sales to the company -- is retaliation for the alleged theft of trade secrets from U.S. technology companies.

But while Applied rivals Lam Research (NASDAQ: LRCX) and KLA-Tencor (NASDAQ: KLAC) both claimed the ban's effect on their businesses was minimal, Applied appears more heavily affected. CFO Dan Durn said during the recent conference call with analysts:

... a quarter ago were expecting our semi business to be flat to up sequentially. We guided down a bit. In the absence of this export restriction, we would've been up sequentially in our semi systems business into Q1. I would say that our revenue with that one customer in Q1 is a meaningful number.

Thus the Jinhua ban made the entire difference between up and down guidance. Considering cyclical investors don't like to buy stocks when earnings are going down, but do like to buy when earnings are going up, that one factor made a rather large difference.

2019 will be more like 2017 than 2018

The memory, semiconductor, and equipment space has experienced a historic boom over the past two years. However, a near-term slowdown in spending, exacerbated by an escalating trade war, has caused spending on memory and semiconductors to decelerate. Still, with many stocks down 40%, 50%, or even 60% from their highs, the question is if the pessimism is overdone.

Applied's management gave numerous reassurances on the sustainability going forward. Said Durn:

... 2019 feels more like 2017 than it does 2018. If I look at where we sit today in 2018 WFE [Wafer Fab Equipment], all-time high in terms of aggregate spend, and strength across each of the four device types. As I profile off of that view into '19, we would expect memory to be down and foundry logic to be up.

In other words, just because 2019 might be a bit lighter than 2018, Durn reminds investors that 2018 was an all-time record, and that industry dynamics are strong. Management says it sees a "U-shaped recovery" rather than a "V-shaped" recovery, but it does see a recovery. Durn said that he would be "extremely disappointed" if the industry sold only $50 billion of equipment in 2025. The industry's current run rate is in the mid-$40 billion range.

The industry needs new technologies

Finally, perhaps the biggest concept to understand about the semiconductor industry is the end of Moore's Law, which is the idea that computing power roughly doubles every two years, by virtue of being able to pack twice as many transistors onto a chip. Moore's Law had proved very accurate over the history of the technology industry ever since Gordon Moore coined the concept in 1965.

However, eventually Moore's Law runs into resistance since chips cannot become infinitely small. Applied Materials sees the end of Moore's Law coming soon, or at least the end of Moore's Law with existing techniques and materials.

CEO Gary Dickerson said the industry needs "a new playbook" to increase computing power going forward, requiring "the development of entirely new chip architectures, new 3D structures within the chip, the integration of new, exotic materials, new ways to shrink feature geometries, including EUV [extreme ultraviolet] lithography and self-aligned patterning, and advanced package techniques to connect chips together in new ways. All five of these areas require major advances in materials engineering."

Dickerson is making the case that if the industry wants to make more and more powerful chips, it will need new processes and new innovations from companies like Applied. If you agree, Applied could be a great long-term buy. Given that Applied's R&D budget is much bigger than those of its rivals, Applied looks like a good bet to play the recovery of the sector.
