Timefolio’s new TIME KOSDAQ Active ETF recently executed a significant and decisive portfolio rebalance.
This move was triggered by a dramatic event involving one of its key holdings, Samchundang Pharmaceutical (SCD). In late March, SCD's stock price soared after it announced a clinical trial filing in Europe for an oral insulin candidate. The excitement was so intense that SCD briefly became the largest company on the KOSDAQ market by market capitalization. This rally meant the ETF, which held a significant stake in SCD, initially benefited.
However, the situation reversed almost overnight. The Korea Exchange (KRX) issued a notice flagging SCD for potential non-compliance with disclosure rules. This announcement, combined with questions about patents and ownership, shattered investor confidence. SCD’s stock price plummeted, falling over 60% from its peak in just over a week.
Because SCD was a top-three holding in the ETF, this crash had a direct and severe impact on the fund's performance. It's estimated that the drop in SCD's stock alone dragged down the ETF's Net Asset Value (NAV) by approximately 4.6% during that period. This single stock's collapse was responsible for a large portion of the fund's poor performance right after its launch.
In response, the fund manager took swift action. On April 7, they executed a major rebalance. This wasn't a sign of a flawed strategy but rather an active risk-management decision to protect the fund from further damage. First, they drastically cut the number of holdings from 74 to 45. Second, they significantly reduced exposure to the biotech sector, including SCD and ABL Bio. Third, they pivoted toward sectors with stronger near-term momentum, such as IT and semiconductor components, increasing their holdings in companies like ISC and Fadu.
This pivot was quickly validated. In the days following the rebalance, several of the newly emphasized semiconductor and optics stocks rallied, suggesting the manager made a timely decision to shift away from the unpredictable biotech risk and toward a more stable growth area. The story of this ETF’s early days is a clear example of active management responding to an unexpected, single-stock shock.
- Net Asset Value (NAV): The per-share market value of an ETF. It's calculated by dividing the total value of all the securities in its portfolio by the number of shares outstanding.
- Idiosyncratic Risk: Risk that is specific to an individual asset, like a single company's stock, rather than the market as a whole. SCD's disclosure issue is a perfect example.
- Rebalancing: The process of realigning the weightings of a portfolio's assets. This involves periodically buying or selling assets to maintain a desired asset allocation.
