About WISIX

The William Blair International Small Cap Growth Fund Class I is a mutual fund designed to invest primarily in a diversified portfolio of equity securities issued by small-cap companies located outside the United States. Its main objective is to seek capital preservation and appreciation by focusing on businesses with superior quality and growth characteristics across developed and emerging markets, excluding the U.S. The fund targets firms that fall within the bottom 30% of market capitalization in their respective regions, emphasizing exposure to sectors such as financial services, industrials, and communication services. The portfolio is actively managed with a mid-growth investment style, maintaining moderate turnover to adapt to evolving market opportunities. With a competitive cost structure positioned in the second-lowest quintile among peers and an institutional share class, the fund is geared towards larger investors seeking international diversification within the small-cap growth segment. By concentrating on foreign small-cap equities, the fund plays a significant role in providing access to global growth opportunities that may be underrepresented in traditional portfolios.
