Six Top Stock Advisor Picks Surged Over 25%—Are They Worth Buying Higher?

When the Motley Fool Stock Advisor team unveiled their top 10 stock recommendations last December, few expected such dramatic results. Six of those picks—dLocal, CrowdStrike, Nvidia, TSMC, ASML, and Alphabet—delivered gains exceeding 25% in 2025, crushing the S&P 500’s performance and validating the advisory’s track record. But now that these stocks have already made their move, investors face a critical question: can they deliver an encore in 2026, or has most of the upside already been priced in?

The stock advisor framework always emphasizes that past performance doesn’t guarantee future returns, yet the evidence from this batch of winners suggests the story isn’t over for all of them. However, distinguishing between those capable of repeating their success and those facing valuation headwinds requires a deeper look at the fundamentals driving each name.

The Trio Positioned for Round Two

Among the six big winners, three stocks stand out as candidates to replicate or exceed 2025’s stellar performance. Nvidia and TSMC remain the cornerstones of the artificial intelligence infrastructure boom. Nvidia produces the graphics processing units that have become essential for training and deploying generative AI applications, while TSMC manufactures the logic chips embedded in these devices. Both companies are riding a wave of corporate AI spending that shows no signs of abating, positioning them to deliver exceptional returns again in 2026.

dLocal presents a different but equally compelling opportunity. The payment processing platform enables companies to tap into emerging market opportunities through integrated plug-in solutions. Although the stock still trades 80% below its all-time high, 2025’s recovery reflected not just newfound investor enthusiasm but genuine business expansion in underserved markets. Analysts tracking this space believe dLocal has significant runway remaining, making it a credible candidate for another 25% plus performance next year.

When Valuation Becomes the Story

The other three top stock advisor performers—CrowdStrike, ASML, and Alphabet—present a different thesis. All three remain fundamentally sound businesses, and portfolio managers still believe they’ll outpace the broader market in 2026. However, their valuations have expanded to levels that could limit additional upside.

ASML and Alphabet trade at 43x and 29x forward earnings respectively, valuations that price in substantial growth assumptions. For a semiconductor equipment maker and a search-advertising giant, these multiples leave little room for sentiment shifts. CrowdStrike commands a 25x sales multiple—not unreasonable for a high-growth cybersecurity firm, but elevated enough to cap further expansion opportunities. These premium valuations mean that while these three could still beat the market, they’re unlikely to repeat 2025’s magnitude of gains.

The Stock Advisor Framework Going Forward

The stock advisor philosophy has long emphasized identifying quality companies before the market fully recognizes their potential. The 2025 results demonstrate this approach works, but the divergence between the three true growth stories and the three valuation-constrained names highlights an important principle: timing and entry points matter.

For investors who followed the top 10 list and captured these gains, the decision point in early 2026 isn’t whether to exit, but which positions to hold and which to reassess. Nvidia, TSMC, and dLocal still offer compelling long-term narratives. CrowdStrike, ASML, and Alphabet deserve holding periods, but they may not deliver the outsized returns that characterized 2025.

The broader stock advisor community has identified a fresh set of top 10 recommendations for forward investors, a list that notably excludes Nvidia this time—suggesting that even exceptional companies have optimal entry windows. History supports this view: Motley Fool subscribers who invested in Netflix at the December 2004 recommendation saw that $1,000 position appreciate to $450,525 by early 2026. Similarly, those who bought Nvidia following the April 2005 recommendation accumulated $1,133,107 from the same $1,000 investment.

This 937% average return from Stock Advisor positions vastly exceeds the S&P 500’s 195% performance, underscoring the value of disciplined stock selection. Investors seeking exposure to emerging trends should examine whether their portfolio reflects the current top 10 stock advisor picks or remains anchored to last year’s winners at fuller valuations.
