Expensive Growth Traps Tech Stocks, MongoDB Case in Point
MongoDB’s impressive numbers weren't enough to silence concerns over its sky-high valuation.
When a company posts 30% revenue growth and nearly doubles its profits, a price drop shouldn’t be the headline. MongoDB’s 10-14% plunge suggests the market is more interested in math than momentum. Trading at 63 times forward earnings, the stock is priced for perfection in a world where investors expect explosive growth, often fueled by AI hype. South African investors may not find a direct equivalent on the JSE, but the lesson is clear: avoid paying through the nose for steady growth. This caution also applies when the USD/ZAR exchange rate swings; a stronger rand can magnify disappointment in expensive foreign tech holdings. Watch for chances to redeploy capital into SA counters like Naspers or Prosus, where valuation and tech exposure strike a better balance. Still, if MongoDB manages to accelerate beyond current growth expectations, the market may regret this sell-off. this is just our opinion and not financial advice
Trim exposure to expensive international tech stocks like MongoDB and tactically increase positions in well-priced JSE-listed tech plays such as Prosus. Use USD/ZAR moves to gauge timing.

- Prosus
- USD/ZAR
- MongoDB outperforms its growth targets
- Rand depreciates sharply, inflating foreign earnings in ZAR terms
6/10
MongoDB stock plunged 10-14% on Wednesday despite delivering a beat-and-raise quarter with 30% revenue growth to $772M and 90% EPS growth to $1.90. The company raised full-year guidance to $3B revenue and $6.49 EPS. However, investors were disappointed by the stock's expensive valuation at 63x forward earnings and 31x next year's earnings, which couldn't justify the low-double-digit growth rate.
