Insuring portfolio

Hello, Are there any good ways to insure ETF portfolio (50% vwce, 25% emim, 25% exus) against sudden market drops? I really don't understand options, and on top of that it seems that EU market pretty much has none. What I am looking is something I could do to limit my downside to something max - 20% within 6 months; what are my best options? Using interactive brokers submitted by /u/Himent [link] [comments]
