The fund is non-diversified, indicating a concentrated investment approach within the bio-revolution theme, making it suitable for investors seeking targeted exposure to this specific area. ## Risk Profile WDNA's concentration in the Healthcare sector (91.9%) exposes it to sector-specific risks, meaning that the fund's performance is closely tied to the performance of the healthcare industry and any adverse events affecting this sector could significantly impact the fund's value.
