He's been shorting WTI since it was $60. Not hard to figure out that's not gone well since it closed at $105 Friday. The good trade is not Oil itself it's too volatile. The trade is long Oil producers that make boat loads of money at $70 WTI. But I agree with you it requires a lot of monitoring and focus; I gave Ken the same warning but given his ego he ignored me entirely.
I try to keep things simple when it comes to oil ETFs. Back when oil was around negative territory, I purchased 15K shares of XEG for an average price around $4 which within 24 months is inching close to 4x that. My main regret is that I did not put in a whole block-order purchase, but I was still sniping other equities. I also made a boatload of cash by shorting puts on all the 2-year leaps for it, and pretty much was the primary seller of all the open interest from strikes of 4 down to 2. Somewhere I may have kept screenshots to prove it someday. Haw! It's amazing how much premium people will pay you when they think an ETF is headed to 0. Doesn't that sound silly now. Amazing what difference in extremes just 2-years can make.
