Competition is heating up in the electric vehicle, or EV, space.
Tesla Inc. (Nasdaq: TSLA) has enjoyed its position as EV king for a while now. But automakers big and small are ready to cut into TSLAās market share in a big way.
Just look at some of these headlines:
- āHigh Demand for Ford EVs: Lightning, Mach-E, and E-Transit”
- āAutomakers Stock up on Batteries in the Growing EV Raceā
- āGM can āAbsolutelyā Catch Tesla in EV Sales by 2025, says CEO Mary Barraā
The Money & Markets team is always looking for the best ways to invest in the biggest stock mega trends. And EVs will be one of the most lucrative opportunities of the next decade.
The global EV market hit a value of $171 billion in 2020. Statista expects it to grow to $725 billion by 2026 ā a 320% increase in only five years!
I want to focus on that last headline and pit Tesla against General Motors Co. (NYSE: GM) to see which is a better buy for the electric vehicle stock mega trend now.
CEO Barra Is Confident GM Can Catch Tesla
GM CEO Mary Barra is confident the American automaker can overtake Tesla by 2025. She said in a recent interview with CNBC:
I am very comfortable because when people get into these vehicles, they are just wowed. So we will be rolling them out and weāre going to just keep working until we have number one market share in EVs.
Teslaās EV market share was 79% in 2020. IHS Markit expects that to drop to 56% in 2021 and all the way to 20% in 2025.
That leaves the door wide open for other players. (Enter GM.)

Tesla Inc.ās Green Zone Rating on October 29, 2021.
Tesla rates a 48, which is āNeutralā on our scale. That means we can expect the electric vehicle stock to perform in line with the overall market over the next 12 months.
At first glance, that isnāt impressive. But the individual factor ratings tell a different story.
TSLA rates a perfect 100 on growth! Looking at its latest earnings report, the EV stock giantās $13.7 billion in reported revenue for the second quarter of 2021 was a 56% increase from the same quarter in 2020.
Its net income also increased 388% year over year!
TSLA touts an 83 momentum rating. Adam is always on the lookout for stocks exhibiting āmaximum momentum,ā and TSLA fits the bill. Just look at its stock chart:
Teslaās Stock Soared Over the Last Month

Source: Yahoo Finance.
Tesla stock gained more than 38% over the last month. Itās trading at all-time highs.
Of course, the stock isnāt cheap, according to our value metric. It only rates a 5 on the value factor, and it carries a 349 price-to-earnings ratio. Investors seem comfortable paying a premium for growth. Itās hard to argue when the stock jumps almost 40% in one month.
GM is in a similar spot, going by its overall Green Zone Rating of 57.

General Motor Co.ās Green Zone Rating on October 29, 2021.
GM stock has enjoyed a run-up in 2021 as well. Itās gained around 33% year to date.
While Tesla is a pure EV stock play, GM is a standard automaker that is shifting its business model into the EV space. And its 96 value rating reflects that. Its P/E ratio is only 7 compared to TSLAās P/E ratio of 349.
But it sports a 76 growth rating as well. GMās revenue grew 103% year over year, according to its most recent earnings report.
The Better EV Stock to Buy
Itās hard to ignore the EV stock mega trend. TSLA and GM donāt rate āBullishā or āStrong Bullishā in our Green Zone Ratings system.
However, Teslaās maximum momentum makes it worth a look, at least for a short-term play.
And GM is determined to cut into that market share over the next decade.
But if you want Adam OāDellās most promising play on the EV stock boom, youāve got to check out Green Zone Fortunes. Adam recently recommended a company that is coming for TSLAās lunch money. And it rates a āStrong Bullishā 90 in Green Zone Ratings!

Green Zone Rating on October 29, 2021.

Green Zone Ratings Factors
Momentum ā Strongly uptrending stocks earn higher momentum ratings. We prefer to buy stocks that are already trending higher and at a faster rate than the overall market. This approach can increase our odds of success and decrease risk.
Value ā Less expensive (aka ācheapā) stocks earn higher value ratings. We prefer to buy great companies at good prices because the price we pay impacts future returns. Overpaying for a stock can be a costly mistake.
Quality ā High-quality companies earn higher quality ratings. We prefer to buy high-quality companies, of course! To determine quality, the model considers a companyās returns, profit margins, cash flows, debt ratios and operational efficiency, among other things.
Growth ā High-growth companies earn higher growth ratings. All things equal, we prefer to buy companies that are growing both revenues and earnings at faster rates than the market and economy.
Size ā Smaller companies earn higher size ratings. We prefer to buy smaller companies for the extra ājuiceā that typically comes with them.
Volatility ā Less volatile stocks earn higher volatility ratings. We prefer low-volatility stocks because theyāre proven to generate superior risk-adjusted returns over the long run ā with less heartburn.
Best investing,
