"Recovery time" = the climb only: trough to break-even (0%). "Underwater" = decline + recovery: peak to break-even.
Drawdown net of Italy inflation
Same curve in purchasing-power terms: as on the site, drawdown follows the real view (volatility stays nominal, per methodology)
In real terms declines are deeper and recoveries slower. Monthly price index (Eurostat), held at the last published value.

Portfolio overlap
1 common holdings · ticker match on full official portfolios
How the shared part is computed: for each security held by both funds, only the SMALLER of the two weights counts — a stock at 5% in one fund and 1% in the other overlaps by 1%, not 5%. Summed over all 1 common holdings this gives 99.8%: buying both funds, roughly this share of your money buys the same stocks twice.
