Since 2020, five Magnificent 7 stocks have split their shares, but only two of those splits have outperformed the market. Alphabet (GOOG) delivered 176.5% returns since its July 2022 split, more than doubling the market’s 82.7% gain, Tesla‘s (TSLA) saw its 2020 split generate 135.5% returns. Its 2022 split, however, produced only 32.1% versus the market’s 66.4%.

Stock splits alone do not drive outperformance, and only Alphabet and Tesla’s 2020 splits beat the broader market, while sustained gains depend on execution in AI, cloud, autonomous technology, and competitive positioning rather than lower nominal share prices.

A recent study identified one single habit that doubled Americans’ retirement savings and moved retirement from dream, to reality. Read more here.

Stock splits are frequently touted as bullish catalysts that make shares more accessible to retail investors and spark fresh buying interest. The reality is far more prosaic: a split changes nothing fundamental about the underlying business. You are simply handed thinner slices of the exact same pie, now priced lower per share.

Since 2020, five of the vaunted Magnificent Seven stocks have executed splits -- Apple (NASDAQ:AAPL), Amazon (NASDAQ:AMZN), Alphabet (NASDAQ:GOOG)(NASDAQ:GOOGL), Nvidia (NASDAQ:NVDA), and Tesla (NASDAQ:TSLA) -- while Meta Platforms (NASDAQ:META) has never split and Microsoft's (NASDAQ:MSFT) last split occurred all the way back in 2003.

The post-split track record for the five has been underwhelming at best. Only two of these stocks have outperformed the S&P 500 since their respective split dates. Shares often pop in the immediate aftermath of hype and increased liquidity, yet those gains prove fleeting. The data make one thing clear: a stock split alone is never a reason to buy.

Most Americans drastically underestimate how much they need to retire and overestimate how prepared they are. But data shows that people with one habit have more than double the savings of those who don’t.

Among the five Magnificent Seven names that split since 2020, the results are lopsided. Most have failed to keep pace with the broader market, underscoring that structural changes like splits do not alter growth trajectories or competitive advantages.

Only Alphabet and Tesla’s 2020 split delivered market-beating returns. The other three splitters -- Apple, Amazon, and Nvidia -- trailed the S&P 500, while Tesla's second split underperformed even more dramatically.

Alphabet and Tesla’s initial 2020 splits stand alone as success stories. The former has delivered a stunning 176.5% return since its July 18, 2022, 20-for-1 split -- more than double the S&P 500’s 82.7% gain over the same stretch. That outperformance stems from Alphabet’s dominant search franchise, accelerating YouTube ad revenue, and early bets on cloud and AI that are now paying off handsomely. With AI-driven search enhancements and Gemini model momentum, Alphabet retains ample runway to push significantly higher in the years ahead. Analysts see continued double-digit revenue growth fueled by the shift to AI-powered advertising and enterprise cloud services.

Tesla’s 2020 five-for-one split produced a 135.5% gain against the S&P 500’s 105.6%. The timing coincided with explosive EV adoption, record deliveries, and the early narrative around autonomous driving. Today, with Full Self-Driving technology advancing, energy storage scaling, and potential robotaxi launches on the horizon, Tesla retains the same disruptive potential that powered its earlier surge.

Both stocks illustrate that when strong fundamentals align with a split’s psychological boost, outperformance can continue well beyond the initial pop. Nothing prevents either from climbing substantially higher if execution continues.

The remaining splitters -- Apple, Amazon, Nvidia, and Tesla’s 2022 follow-on -- have lagged, raising the question of whether they can recover. Apple's near doubling since its 2020 split trails the S&P by six percentage points. While iPhone cycles have matured, services revenue and emerging AI features in Apple Intelligence could spark fresh momentum.

Amazon's post-2022 split return of 66.4% trails the market by nearly four points, yet AWS AI workloads and e-commerce efficiency gains offer clear catalysts for a rebound. Nvidia's 48% post-June 2024 split gain looks especially weak against the S&P’s 86.6%, but the company’s CUDA moat and Blackwell chip ramp still position it as the AI hardware leader -- suggesting any valuation digestion may prove temporary. Even Tesla's 2022 split, which returned just 32.1% versus the S&P’s 66.4%, sits in a stock that remains tied to the same long-term EV and autonomy story, but also has robotics and AI tailwinds to push it higher.

Whether these laggards rebound hinges less on the splits themselves and more on execution in AI, cloud, autonomous tech, and consumer spending. Splits may lower the psychological barrier to entry, but sustained outperformance will still be decided by earnings power and competitive positioning -- not by how many shares trade at a lower nominal price.

Most Americans drastically underestimate how much they need to retire and overestimate how prepared they are. But data shows that people with one habit have more than double the savings of those who don’t.

And no, it’s got nothing to do with increasing your income, savings, clipping coupons, or even cutting back on your lifestyle. It’s much more straightforward (and powerful) than any of that. Frankly, it’s shocking more people don’t adopt the habit given how easy it is.
