Be very careful with the Horizons products. They DO NOT track the indexes accurately and you will lose money even if it goes sideways. They are meant to hold for very short periods of time. Keep in mind that snowflake governments in western world have made it very clear that they won't allow anybody to suffer not even a knee scrape. Shorting is dangerous even now
Yes, the HBP 'double/double down' ETFs are not for the feint of heart.
Really should only be used for short term plays and in volatile times, ensure that you use 'stop loss orders' which if you guess 'wrong' will be triggered very, very quickly.
That said, if you have a good handle on the direction of whichever market you are 'betting on', the gains on the upward or the downward side of the market will be doubled the market index which it attempts to mirror.
Just think, the overall Feb/Mar 2020 market tumble of close to 35% would have realized you a gain of 70% of bought and held HSD ETF.
And the insane FED fed and backstopped rally from the market low of March 23, 2020 to date would have realized you a gain of close to 200% of bought and held the HSU ETF.
