GDXD is an Exchange Traded Note (ETN) meticulously crafted to provide three times (3x) the inverse daily return of its benchmark index. This instrument is not intended for long-term investment, but rather specifically designed for short-duration, tactical trading strategies. Investors should be aware that holding GDXD for longer than a single trading day can lead to returns that diverge substantially from the expected -3x leverage due to daily compounding effects.
