$4.07M moved through Transocean LTD. ($RIG) options on Friday in a 2-leg trade built around the $5 to $5.50 strikes. The legs lean bullish: the bought side profits as Transocean rises, and the sold side helps pay for it.
What happened
The legs printed together in the final half hour, around 3:45 p.m. ET on Friday, September 25, with $RIG near $5.40, for $4.07M in combined premium across 36,000 contracts.
Trading the legs as one ticket locks in the price of the whole structure at once, which is how professional desks usually put on spreads.
Netting the legs, the trader paid about $4.07M to put the position on. With no sold legs, that debit is also the most the trade can lose.
- RIG Jan 21, 2028 $5 Put: 18,000 contracts at $0.90 (bought)
- RIG Jan 21, 2028 $5.50 Call: 18,000 contracts at $1.36 (bought)
Why it matters
A strangle pairs a call and a put at different strikes. It is a view on how far the stock moves, more than which way.
Net of all legs, the structure behaves like being long roughly 580,700 shares of RIG, about $3.13M of stock exposure.
The strikes run from $5.00 (7.3% below the stock) to $5.50 (1.9% above the stock), so the trade is built around a zone rather than a single target.
With 482 days until Jan 21, 2028, this is a long-dated position measured in years, the kind of trade built around a thesis rather than the next headline. Implied volatility ran around 50%, elevated, which means traders are paying up for movement.
The numbers
| Structure | Strangle (2 legs) |
|---|---|
| Lean | Bullish |
| Expirations | Jan 21, 2028 (nearest in 482 days) |
| Strikes | $5, $5.50 |
| Contracts | 36,000 |
| Total premium | $4.07M |
| Net cost | $4.07M debit |
| Stock at the trade | $5.40 |
Three ways this could play out
Bullish continuation
A move through $5.50 puts $RIG above every strike. That is where this bullish structure does its best work.
Bearish rejection
A drop under $5.00 takes $RIG below every strike. With the lean on the bullish side, that is where the position takes its worst damage.
Neutral stabilization
If $RIG settles between $5.00 and $5.50 into Jan 21, 2028, a short strangle keeps its premium and a long one fades.
What to watch next
- $5.00 and $5.50: the outer strikes that define this trade.
- Open interest on each leg in the next session, to confirm the structure was opened rather than closed.
- Jan 21, 2028: expiration, 482 days out for the nearest leg, when the structure resolves.
- Follow-on spreads at nearby strikes, which would show a desk building a larger position.
