2025 Market Recap + What to Watch in 2026

2025 wasn't the year of AI stocks - it was the year of memory stocks. Here's what happened, what Wall Street expects for 2026, and how to navigate it.

2025 wasn't the year of AI stocks. It was the year of memory stocks.

While everyone debated whether NVDA was overvalued, data storage companies quietly delivered 200-500% returns. Here's what happened, what it means, and where we go from here.


Part 1: 2025 By The Numbers

The Big Picture

The S&P 500 delivered another strong year - up roughly 17-18% as of late December. That's three straight years of gains:

  • 2023: +24%
  • 2024: +23%
  • 2025: +17-18%

Not bad for a market that "experts" kept calling overvalued.

Winning Sectors

| Sector | 2025 Return | |--------|-------------| | Technology | +26% | | Communication Services | +22% | | Industrials | +19% | | S&P 500 (overall) | +17-18% |

Tech led again, but the real story is which tech stocks led.

The Surprise Winners: Data Storage

If 2023-2024 were the years of AI compute (NVDA, AMD), 2025 was the year of AI infrastructure. The market figured out that all those AI models need somewhere to live - and that means memory and storage.

| Stock | 2025 Return | Why | |-------|-------------|-----| | SanDisk (SNDK) | +587% | Spun off from WDC, AI data center demand | | Western Digital (WDC) | +292% | Memory/storage for AI workloads | | Micron (MU) | +228% | HBM chips for AI, data center growth | | Seagate (STX) | +226% | Enterprise storage demand | | Robinhood (HOOD) | +225% | Retail trading boom, crypto exposure |

The top 5 S&P performers weren't the names everyone was watching.

AI Stocks: Still Strong, But Not #1

The "obvious" AI plays still delivered solid returns:

  • Palantir (PLTR): +155%
  • Nvidia (NVDA): +35%

But they weren't the biggest winners. The market moved downstream from "who makes AI chips" to "who stores AI data."

The Concentration Problem

Here's the uncomfortable truth: five stocks accounted for nearly 45% of the S&P 500's returns. The tech sector's weight in the index hit 36% - a record that surpasses even the 2000 dotcom peak.

That's not necessarily bad, but it's worth understanding. When you buy "the market," you're really buying a handful of mega-caps.


Part 2: What Worked and What Didn't

What Worked in 2025

1. Betting on AI infrastructure, not just AI hype

The smart money followed the supply chain. Compute was 2024's story; memory and storage were 2025's story.

2. Staying invested despite "overvaluation" fears

Every month brought new warnings about stretched valuations. Those who stayed invested made 17%+. Those who waited for a correction are still waiting.

3. Following the Mag 7 (again)

Love them or hate them, the mega-caps kept delivering. GOOGL, MSFT, NVDA, and friends carried the index once more.

What Didn't Work

1. Waiting for a major correction

The 10-20% pullback never came. Markets can stay "overvalued" longer than you can stay patient.

2. Rotating too early into "value"

The value rotation trade has been "coming" for three years. It hasn't arrived yet.

3. Fighting the Fed

The market figured out the Fed's path before the Fed did. Fighting that narrative cost people money.


Part 3: What Wall Street Expects for 2026

The Consensus: Bullish

Here's something unusual: of 21 major Wall Street firms surveyed, zero are predicting the market will decline in 2026. Not one.

If they're right, it would be the fourth consecutive up year - the longest winning streak in nearly two decades.

S&P 500 Price Targets for 2026

| Firm | Target | Implied Return | |------|--------|----------------| | Oppenheimer | 8,100 | +35% | | Deutsche Bank | 8,000 | +33% | | Morgan Stanley | 7,800 | +30% | | Wells Fargo | 7,800 | +30% | | JPMorgan | 7,500 | +25% | | Bank of America | 7,100 | +18% |

Even the most cautious (Bank of America) sees double-digit gains.

What's Driving the Optimism?

1. AI Capital Expenditure

Big tech is expected to spend approximately $520 billion on AI infrastructure in 2026. That money flows through the entire supply chain - chips, memory, data centers, power infrastructure.

2. Earnings Growth

Morgan Stanley projects S&P 500 earnings to grow 14-17% in 2026, taking EPS to around $317-320.

3. Market Broadening

Analysts expect gains to spread beyond the Mag 7. All 11 S&P sectors are projected to rise - a healthier dynamic than 2025's concentration.


Part 4: Risks to Watch

Wall Street consensus is bullish, but consensus is often wrong. Here's what could derail the rally:

1. Midterm Election Year Volatility

2026 is a midterm election year. Historically, these years bring more volatility as policy uncertainty increases.

2. AI Bubble Concerns

What if the AI spending doesn't deliver ROI? Companies are pouring billions into AI infrastructure. If enterprise adoption disappoints, those investments could sour sentiment quickly.

3. Fed Uncertainty

The rate path is unclear. Markets are pricing in 2 cuts, but sticky inflation or economic surprises could change that. The Fed has surprised before.

4. Concentration Risk

When 5 stocks drive 45% of returns, a stumble in mega-caps could drag the entire index. Diversification only works if you're actually diversified.

5. Valuation

The market isn't cheap. A lot of good news is already priced in. That doesn't mean it can't go higher, but the margin for error is smaller.


Part 5: What We're Watching in 2026

Established Themes

Memory/Storage

The AI infrastructure story isn't over. MU, WDC, and storage names could continue if AI data center buildout accelerates. We'd look to add on pullbacks rather than chase at highs.

AI Infrastructure Over Hype

Follow the capex. Companies actually spending on AI (hyperscalers, enterprise) are more interesting than companies just talking about AI.

Market Broadening

If small caps and value finally participate, it could be a healthier rally. Keep an eye on equal-weight S&P (RSP) vs. cap-weight (SPY) to track this.

Defense/Aerospace

Geopolitical tensions aren't going away. Defense contractors and aerospace names offer exposure to government spending regardless of who's in office.

Emerging Moonshots

These are speculative, long-term themes - not 2026 trades. But they're worth having on your radar:

| Sector | Why It's Interesting | Names to Watch | Risk Level | |--------|---------------------|----------------|------------| | Quantum Computing | Google's Willow chip breakthrough, IBM roadmap accelerating | IONQ, RGTI, IBM, GOOGL | Very High | | Space | SpaceX IPO buzz lifting sector, satellite demand, defense spending | RKLB, LUNR, ASTS | High | | Robotics | AI + automation convergence, labor costs rising, manufacturing reshoring | Harmonic Drive (6324.T), Cognex (CGNX), Rockwell (ROK) | Medium-High |

Our take: Size these small. They're 5-10 year bets, not swing trades. Expect 50%+ drawdowns along the way. But if you want exposure to the next wave of tech, these sectors are where to look.


Part 6: How to Navigate 2026

Here's our practical framework for the year ahead:

1. Stay Invested, Stay Diversified

Three straight up years feels unsustainable, but markets can stay irrational longer than you can stay patient. Don't try to time the top.

2. Follow the Data, Not the Headlines

Earnings, revenue growth, margins - these matter more than daily news cycles. Set up alerts for the stocks you care about and let the data guide you.

3. Have a Plan Before You Need One

Know your entry and exit points. If your stock drops 20%, will you add or panic sell? Decide now, not in the moment.

4. Watch the Concentration

If you're heavy in tech/mega-caps (most people are), consider whether you're actually diversified. A 40% tech allocation isn't diversification - it's a sector bet.

5. Keep Learning

The market evolves. AI infrastructure wasn't on anyone's radar in 2023. By 2025, it was the top trade. Stay curious about what's next.


The Bottom Line

2025 rewarded those who stayed invested, followed the supply chain, and didn't overthink it. Memory stocks delivered 200-500% returns while everyone debated NVDA's valuation.

2026 looks bullish on paper - every major Wall Street firm expects gains. But consensus rarely predicts surprises. The risks (AI bubble, concentration, Fed uncertainty) are real.

Our approach: stay invested, stay diversified, and let the data guide us. We use StockGenie to track our watchlist, set alerts for key levels, and get AI-powered analysis when we need to make decisions fast.

Whatever happens in 2026, the best strategy is the same as always: understand what you own, have a plan, and don't panic.
