JGLO's 15% gain over the past year stems from heavy concentration in mega-cap technology. The fund places over a quarter of its assets in just six companies-NVIDIA ( NASDAQ:NVDA), Microsoft ( NASDAQ:MSFT), Apple ( NASDAQ:AAPL), Amazon ( NASDAQ:AMZN), Alphabet ( NASDAQ:GOOGL), and Meta. This concentrated approach explains both the fund's recent gains and its vulnerability to tech sector rotation. When Tech Dominance Becomes a Double-Edged Sword The biggest factor shaping JGLO's future is whether mega-cap technology stocks can sustain market leadership or if returns are broadening.
