> Note: The time period was constrained by the available data for AXS Short Innovation Daily ETF (SARK) [Dec 2021 - Feb 2023]. Including monthly investment doesn't really help, either.[1] [1]: https://www.portfoliovisualizer.com/backtest-portfolio?s=y&timePeriod=2&startYear=2012&firstMonth=12&endYear=2023&lastMonth=2&calendarAligned=true&includeYTD=false&initialAmount=10000&annualOperation=1&annualAdjustment=1000&inflationAdjusted=true&annualPercentage=0.0&frequency=2&rebalanceType=1&absoluteDeviation=5.0&relativeDeviation=25.0&leverageType=0&leverageRatio=0.0&debtAmount=0&debtInterest=0.0&maintenanceMargin=25.0&leveragedBenchmark=false&reinvestDividends=true&showYield=false&showFactors=false&factorModel=3&benchmark=-1&benchmarkSymbol=VTI&portfolioNames=false&portfolioName1=Portfolio+1&portfolioName2=Portfolio+2&portfolioName3=Portfolio+3&symbol1=ARKK&allocation1_1=100&allocation1_2=0&symbol2=SARK&allocation2_1=0&allocation2_2=100 https://www.portfoliovisualizer.com/backtest-portfolio?s=y&t...

SARK is the inverse of ARK, it's not necessary for analysis, so remove it. ARK tripled in value from April 2020 to Feb 2021. So you get very different results by picking a start date in 2020 or earlier.

  You replied to a post above about the inverse ETF, suggesting that that poster was cherry-picking dates. The entire point of the inverse ETF was to take advantage of the ARKK's unrealistic returns in the preceding year. Just for kicks, though, here's ARKK versus VTI and cash since April 2020.[1] [1]: https://www.portfoliovisualizer.com/backtest-portfolio?s=y&timePeriod=2&startYear=2020&firstMonth=4&endYear=2023&lastMonth=2&calendarAligned=true&includeYTD=false&initialAmount=10000&annualOperation=0&annualAdjustment=1000&inflationAdjusted=true&annualPercentage=0.0&frequency=2&rebalanceType=1&absoluteDeviation=5.0&relativeDeviation=25.0&leverageType=0&leverageRatio=0.0&debtAmount=0&debtInterest=0.0&maintenanceMargin=25.0&leveragedBenchmark=false&reinvestDividends=true&showYield=false&showFactors=false&factorModel=3&benchmark=-1&benchmarkSymbol=VTI&portfolioNames=false&portfolioName1=Portfolio+1&portfolioName2=Portfolio+2&portfolioName3=Portfolio+3&symbol1=ARKK&allocation1_1=100&symbol2=CASHX&allocation2_1=0&allocation2_2=100 https://www.portfoliovisualizer.com/backtest-portfolio?s=y&t...

    The fact that the OP had quite a good reason for cherry-picking those particular dates doesn't make them less cherry-picked.

    Yes ARKK has crashed spectacularly but that wasn't the point of the original comment. You would be down now betting against it earlier, it's not like it never gained anything prior.
