Several credible investor-focused sources provide historical and current stock price data for Ichor Holdings. The investor relations stock chart clearly shows significant price appreciation between August (around the date of Debbie Wasserman Schultz's financial disclosure) and the current date. Third-party market analysis platforms confirm similar price movement metrics, aligning closely with an increase of roughly 170% in value over that period. While no source explicitly states her personal investment return, the public disclosure plus confirmed share price history make it straightforward to calculate the approximate growth matching that percentage. No credible contradictory evidence was found, and the relevant sources are high in both authority and relevance, enabling reliable verification of the claim through the publicly available price data.
