Stock splits can be exciting events, right? They certainly draw attention to the splitting company, even if they don't necessarily move the stock price up.

Consider the fates of two would-be splitters, Tesla (TSLA 3.17%) and GameStop (GME 3.71%). Since announcing their respective share divisions in late March, the share prices of both have declined (GameStop by 13.2% and Tesla by 9.6%).

But softening share prices can often make companies more attractive. Let's see which of these contenders is the better buy opportunity right now.

A tale of two splitters

Tesla and GameStop aren't directly comparable as businesses, but they do share some similarities. Both have been criticized for the way they operate in the past and both have come close to bankruptcy at various points in their histories. The two companies are also the subject of constant, and sometimes frenzied, online discussion. This somewhat distorts the value of their stocks, as chatter and noise can knock a company's price around quite a bit.

Let's cut through the static and look at the fundamentals of the pair. Both operate in relatively high-cost and low-margin environments. Tesla cars require thousands of components, some rather expensive, and GameStop has to maintain a decent level of inventory and operate and staff brick-and-mortar stores. Earning a buck for the two companies, then, has been a challenge at times.

Electrifying growth for Tesla

Tesla is a recent arrival to the profit garage. Its bottom line has only recently been consistently in the black. It's managed to do this with a laser focus not only on EVs exclusively -- unlike slower-moving, auto-making competitors who are still beholden to the traditional internal-combustion engine -- but also because the "cool factor" is nicely baked into its vehicles. This is especially true with the popular, higher-end offerings such as the Model X SUV.

This is a business model expertly practiced by Apple, whose iPhone line of products is still the premium smartphone line of choice for many consumers after 15 years. The beauty of this approach is that quality premium products command higher prices and, all things being equal, produce higher margins for their makers. That was a key factor in Tesla's dramatic lurch into profitability.

This success is combined with heady top-line growth. People want to own next-generation cars and desire to own Teslas. Demand continues to be bodybuilder strong and has helped lift revenue higher. Tesla's full-year 2021 sales were nearly $54 billion, a sky-high 71% improvement year over year.

Is it game on or off for GameStop?

During the coronavirus pandemic, GameStop grew to prominence because of the many online denizens posting feverishly about the company. For a time (and still to some extent these days), it was the company that personified the new term "meme stocks," with the outcome of entire trading days dependent on the tone of online discussions.

This kicked off in late 2020 with the most famous short squeeze in recent history. The shorts were ultimately routed, and GameStop began the roller-coaster ride it's still on today.

To be blunt, it's not a good investment based on the business fundamentals. While GameStop hasn't done badly squeezing out sales growth (18% in full-year 2021) lately, it's a retail dinosaur that usually loses money. Over the past four years, its annual loss has ranged from just under $215 million to nearly $800 million. Zooming in, the past three quarters have seen the flailing company slide increasingly deeper into the red on the bottom line.

And the winner is...

In one corner, we have Tesla as the highest-profitable operator in a red-hot segment in which demand shows no sign of cooling. In the opposite corner stands wobbly GameStop, weakened by a legacy business model that's hard to succeed with today and tough to pivot from. The company's also not a hot prospect to excel with behind-the-trend ventures, such as its recently announced non-fungible token (NFT) platform.

I suppose some argument could be made in favor of GameStop being far cheaper on certain, highly selected valuations. The company's price-to-sales ratio, for instance, stands at less than two, while that of ever-expensive Tesla is a bloated 24-plus.

Then again, Tesla is a zeitgeist company with its best years in front of it. GameStop is a gossip-prone, volatile stock fronting a money-losing business.

There's no real competition here. Admittedly, Tesla's valuations give me pause to think and its top management is a bit flaky for my taste, but it's built a powerful brand and will continue to be a leader in its segment. The EV specialist is unhesitatingly my pick in this contest.
