High Growth Stocks 2019: The Year That Rewrote the Rules
The market in 2019 rewarded a narrow set of themes. Low interest rates, a tech-driven earnings recovery, and trade optimism pushed high growth stocks 2019 into a category of their own. Investors who stacked positions in cloud computing, e-commerce, electric vehicles, and modern healthcare saw compounding gains that dwarfed the broader index. The year was not about timing the bottom; it was about identifying businesses with durable revenue momentum and pricing power before the crowd caught on.

What separated the winners was a willingness to pay for secular trends rather than short-term earnings. The year reinforced a simple rule: when growth is scarce and rates are low, the market prices the future aggressively.
Why 2019 Became a Banner Year for Growth
Three forces converged to make high growth stocks 2019 the standout performer. First, the Federal Reserve paused and then reversed its tightening cycle, lowering the discount rate that values future cash flows. Second, corporate tax cuts from 2017 began flowing through to earnings, which helped growth companies fund R&D and expansion without diluting shareholders. Third, the U.S.-China trade war created volatility that favored names with global scale and brand dominance.
The result was a sharp widening of the gap between growth and value. The Nasdaq Composite outperformed the S&P 500 by a wide margin, and the best performers were companies with revenue growth rates well above 20%.
The Sectors That Led the Charge
Cloud Computing and Software
Cloud infrastructure providers and SaaS companies were the backbone of 2019's growth story. Companies that helped enterprises migrate to the cloud saw recurring revenue models rewarded with rich multiples. Investors cared less about current profitability and more about net revenue retention and forward bookings.
E-Commerce and Digital Payments
Consumer spending shifted online throughout the year. Platforms connecting sellers with buyers, plus payment processors enabling those transactions, posted accelerating revenue curves. The thesis was simple: once a platform reaches critical mass, network effects protect margins and fuel compounding.
Electric Vehicles and Clean Energy
Tesla dominated headlines, but the broader EV and battery supply chain attracted capital throughout 2019. Government incentives in China and Europe, combined with falling battery costs, made the sector attractive for long-duration growth investors.
Modern Healthcare and Biotech
Biotech firms with promising pipelines and blockbusters near-term launched strong runs. The sector benefited from an aging population and a willingness to pay for innovation, though individual stock outcomes depended heavily on clinical data and FDA catalysts.
Top Performers and What Drove Their Returns
While individual stock picks varied, the common thread among the top high growth stocks 2019 was consistent: revenue acceleration, expanding gross margins, and a narrative that justified a premium valuation. The table below highlights the kind of companies that defined the year.
| Sector | Growth Driver | Valuation Signal | Context |
|---|---|---|---|
| Cloud Software | Recurring revenue, net expansion | Rule of 40 above 25 | Low rates favored long-duration cash flows |
| E-Commerce | Marketplace take rate, GMV growth | Sales growth over 30% | Shift in consumer spending habits |
| EV / Auto Tech | Delivery growth, battery tech | Narrative plus pre-orders | Regulatory tailwinds in key markets |
| Biotech | Pipeline catalysts, approvals | Risk-adjusted pipeline value | Aging demographics, innovation cycle |
None of these names were cheap by traditional metrics. The premium was the bet: that growth would compound faster than the valuation multiple expanded.
Lessons for Investors Today
The high growth stocks 2019 story offers a playbook that still holds when conditions align. Look for revenue momentum that is self-reinforcing, not dependent on one-time deals. Prefer businesses where capital expenditure is already behind them and free cash flow is improving. And understand that high growth stocks can compress sharply when rates rise or when earnings miss, so position sizing and patience matter as much as the pick itself.
The year also taught a cautionary lesson: not every high-flying name sustains. Some stocks doubled on hype, then gave it all back. The winners were the ones with durable competitive advantages, not just a catchy pitch.
What to Watch When Screening for High Growth
When evaluating a high growth opportunity, focus on a handful of metrics that matter more than the headline price. Revenue growth rate, gross margin trajectory, customer acquisition cost, and cash flow conversion are a starting point. Management quality and capital allocation discipline often separate the compounding machines from the one-hit wonders.
- Revenue growth: sustained acceleration over multiple quarters
- Gross margins: expanding, not contracting with scale
- Cash flow: operating cash flow growing at or above net income
- Competitive moat: network effects, switching costs, or scale
- Management: skin in the game, clear capital allocation priorities
High growth stocks 2019 were not a monolith. Some were priced for perfection and delivered; others were priced for perfection and disappointed. The difference was usually visible in the financials before the headline moved.
