    "classification": "complex",
    "supporting_data": "The ETF uses FLEX Options (customised equity options) to achieve its investment objective, which involves a complex buffer/cap mechanism tied to the Nasdaq-100 Index. The strategy requires understanding of options pricing, exercise styles, and expiration dates, making it unsuitable for retail investors without specialist knowledge. While the ETF is UCITS-compliant and does not use leverage or inverse exposure, the derivative-based structure with predefined outcomes (buffer and cap) introduces complexity beyond simple index tracking. The risk profile (category 5) and the use of customised derivatives for achieving specific outcomes (rather than efficient portfolio management) further support the 'complex' classification.",
    "confidence": 90,
    "counter_argument": "One could argue that the ETF's structure is transparent, with clear buffer/cap mechanics and no leverage, making it understandable for sophisticated retail investors. However, the customised nature of FLEX Options and the predefined outcomes require a level of financial sophistication that aligns with MiFID II's 'complex' criteria.",
    "overriding_reason": "The use of FLEX Options for achieving specific outcomes (buffer/cap) and the customised nature of the derivatives make the ETF's strategy complex, even if the risk profile is moderate. The lack of leverage or inverse exposure does not offset the complexity introduced by the derivative-based structure."
