Paulo Macro — Follow-up to Oil & Retail

"Three Quick Points." An erratum, the UCO counterpart to SCO, why these short-gamma levered ETFs may be "banging the close" and sitting on the illiquid back of the strip, and a thin WTI expiry that echoes a 2022 natgas tell.

One-line take: a same-day follow-up to "Oil & Retail". (1) Erratum: 4mmbpd × $150 = $600mn (not $750mn) — point holds. (2) UCO — the 2× levered long oil ETF (opposite of SCO) — has bled ~half its assets to $440mn (under half SCO's size) and costs 8.3% to short (only 200k shares). Both SCO and UCO are inherently short-gamma: their inflows exacerbate the daily move into the 2:30pm NYMEX settlement (a timing mismatch vs the 4:00pm NAV) — likely the "someone banging the close" (rhymes with "Shmessent") subscribers noticed. Because they hold not just the front month but Dec26/Jun27, their footprint on the increasingly illiquid back-of-the-strip is outsized — "why shale can't hedge farther out: a giant short ETF is sitting on the curve." (3) Molecules vs paper: on WTI May26 (K26/CLK26) last trading day only ~7.5k contracts traded vs 33k on the prior (J26) expiry against similar ~18-20k open interest — a thin, potentially unstable expiry echoing the Henry Hub Feb-2022 (NGG22) last-day tell that preceded a wild move. "If it prints there, it trades there… probably nothing but vibes." UCO is tabled as a new positioning-tell reference; SCO recurs as the short-gamma counterpart. Crude/natgas futures contracts are not tickers.

One new positioning-tell (UCO, the 2× long) is tabled; SCO recurs as its short-gamma counterpart. The WTI May26 (K26/CLK26) and April (J26) futures and the Henry Hub Feb-2022 (NGG22) / March (NGH22) natgas contracts are futures, not tickers.

UCO — ProShares Ultra Bloomberg Crude Oil Neutral

UCO is the mirror image of SCO: it's built to move about twice as much as oil in the same direction each day, so it's a leveraged bet that oil goes up. Paulo isn't recommending it — he's pointing out how these products distort the market. Retail has been fleeing UCO (its pot of money roughly halved to $440mn), and both UCO and SCO share a hidden flaw: they must trade in the same direction as the day's move right before the afternoon oil "settlement" price is struck, which can shove the price around near the close (what some traders mistook for a government official "banging the close"). Worse, these funds hold longer-dated oil contracts that barely anyone trades anymore, so a big fund parked there can distort prices far out into the future — which, Paulo argues, is part of why oil producers can't lock in prices to justify drilling more.
