*For Long vol, this active trading could be as simple as rolling an options spread once a quarter (~10 min on a broker platform). For CTF, this could be as simple as automating an email notification for your preferred trend that you’ll receive a few times in a year, then executing the appropriate trade at that time (again ~10 min on broker platform). If we include time spent rebalancing annually, then I’d say total time spent “actively” managing this portfolio would be as little as a few hours a year.
If that is the amount of time you intend to spend per year, just buy more gold instead. “Active Long Volatility” is first and foremost active.
