Why does my fund show a huge price drop or 'fell off a cliff' in the performance chart?

If a fund's chart shows a sudden 50–85% drop that didn't actually happen, the most common cause is a stock or ETF split that hasn't been reflected yet in PortfolioPilot's historical price series. On a forward split, the per-share price falls proportionally while the share count rises - your dollar value is unchanged, but the historical chart looks like a cliff until we back-adjust the prices.

This is a data issue worth reporting, not just a display quirk - the same back-history feeds historical-return, drawdown, and volatility calculations for the affected ticker, so getting it corrected matters.

Open the holding's Security details view and click Report an issue next to the chart, or email support@portfoliopilot.com with the ticker and the split date (if you know it). We'll rebuild the historical series - we'll investigate and fix it asap.

If it isn't a split, reverse splits, ticker changes, fund mergers, and delistings can produce similar-looking jumps. Same path - report it and we'll investigate.
