This has been one of the most difficult years on record for Wall Street and the investing community. The U.S. economy has delivered back-to-back quarters of gross domestic product declines, the U.S. inflation rate is hitting a more than four-decade high, and Russia's invasion of Ukraine throws an even bigger monkey wrench into an already-damaged global energy supply chain. Perhaps it's no surprise that the benchmark S&P 500 and growth-driven Nasdaq Composite entered bear market territory.

However, the iconic Dow Jones Industrial Average has avoided this fate. The Dow Jones, which is comprised of 30 multinational companies, has likely outperformed the other major indexes because it's packed with profitable, time-tested businesses. In other words, sometimes it pays to invest in mature stocks that just keep winning over time.

With the broader market taking it on the chin, now is as good a time as any for opportunistic investors to put their money to work. What follows are three Dow stocks that are nothing short of screaming buys in September.

1. Intel

The first Dow stock that's begging to be bought by long-term investors in September is semiconductor stock Intel.

Shares of Intel have been halved over the past 18 months. This looks to be due to a combination of the U.S. and global economy weakening, demand for personal computers declining as workers get back to the office, and supply chain concerns continuing to weigh on production. It also hasn't helped that rival Advanced Micro Devices has been chipping away at Intel's market share in its computing and data center segments.

Yet, in spite of these challenges, buying Intel at its current share price looks like an absolute steal for investors who can exercise patience -- and who want to receive a 4.4% annual dividend yield while they wait for Intel's catalysts to carry shares notably higher.

Before writing Intel's eulogy, skeptics should take a closer look at desktop, mobile, and server market share among central processing unit (CPU) developers and manufacturers. As of the end of the first quarter of 2022, Intel respectively controlled almost 82% of desktop CPUs, close to 78% of mobile CPU share, and just over 88% of server CPU share (excluding Internet of Things devices). It doesn't appear that Intel will be losing its high-margin, cash-rich crown anytime soon.

Another reason to be optimistic about Intel is the expected spinoff of autonomous vehicle company Mobileye, which Intel purchased for $15.3 billion in 2017. Mobileye generated record sales of $460 million during the June-ended quarter, which represents an increase of 41% from the prior-year period. With innovation being the name of the game in the auto industry, it's possible Intel's stake in Mobileye could create a nice windfall for the company.
