managment’s discussion of fund performance
The Sparrow Growth Fund – Class A enjoyed positive returns for the year ended August 31, 2026, buoyed in part by favorable stock market conditions. These market conditions were supported by increased capital spending on Artificial Intelligence, including data centers and internet websites and software giants Microsoft and Google. The Fund increased +5.88% (without load) and decreased -0.20% (with load) while the S&P 500 Index increased +20.38%. The difference of returns was due to our allocation to financial services and consumer investments which presents a lower risk than other technology sectors faster paced hardware technology sectors.
Strategy
Our strategy of buying and holding profitable companies with growth potential included Nvidia, Google and Netflix, each of which had a strong, positive impact on Fund performance.
Techniques
Our security selection may lead to lower relative turnover and lower realized capital gains taxes because we tend to be long-term business owners. Our selection process includes companies with above average sales and earnings per share growth. We believe that companies that have sales and earnings growth rates that are above average may produce a return over long periods of time that exceed market averages.
Thank you for your confidence.
