The concentration of MGK's portfolio in a few stocks amplifies the fund's sensitivity to market movements, potentially leading to higher volatility. This could result in significant price swings for MGK, with a direct impact on its net asset value and investor returns. The outperformance of MGK relative to the S&P 500 may attract more investors, increasing demand for the underlying stocks and potentially driving up their prices.
