Iberdrola options flow points to caution near €19.50 with medium-term upside interest

The options flow is defensive in the short term but not decisively bearish overall: puts outnumbered calls by 2.1 to 1, while volatility and downside skew both declined. The message is caution near €19.50, alongside meaningful medium-term interest above €20.

The First Signal

Iberdrola (IBE): Trading at €19.59, down 0.41%, as of September 3, 2026, 7:50 a.m. New York time || Options volume: 25,050 contracts || Put/call volume: 17,033 / 8,017 || Put/call ratio: 2.12

That ratio looks bearish at first glance. However, the largest trades were concentrated in puts near the current price, where investors often hedge existing stock exposure.

Near-Term Protection

The September 18 €19.50 put traded 7,000 contracts, against open interest of 11,150 as of September 2.

Because the strike sits almost exactly at the €19.59 stock price, this is the clearest near-term signal. It suggests investors are focused on protecting, or speculating on, a move toward €19.50 before September expiration.

The trade is defensive, but volume alone cannot show whether puts were bought or sold. If bought, it signals downside protection. If sold, it could indicate willingness to own the stock near €19.50.

December’s Tug Of War

The December 18 €19.50 put accounted for 10,000 contracts, with open interest of 40,960. That is substantial existing positioning, but today’s volume equals only about 24% of open interest.

The December 18 €20 call traded 7,500 contracts, versus just 3,338 open interest. That volume is more than twice existing open interest, suggesting potentially fresh positioning.

This creates a mixed picture:

• €19.50 puts: downside insurance or bearish positioning.
• €20 calls: upside participation just above spot.
• The call’s unusually high volume versus open interest hints at a new bullish counterweight.

Longer-Dated Upside

The March 19, 2027 €20/€22 call spread traded 500 contracts.

A long €20 call combined with a short €22 call generally expresses a moderately bullish, capped-upside view. It targets a gradual rise rather than an explosive breakout.

That structure matters because it contrasts with the short-dated put activity. Traders appear more concerned about near-term turbulence than about Iberdrola’s medium-term upside.

Volatility Gives Clues

Three-month volatility fell to 15.77%, down 0.13 percentage points, as of the quoted session.

The 90/110 skew declined to 3.17 percentage points, down 0.12 points. Lower skew means demand for downside protection eased slightly. Yet positive skew still indicates puts remain more valuable than comparable calls.

Take

Near-term: neutral-to-bearish, with €19.50 acting as the market’s focal risk level.

Medium-term: mildly constructive, supported by €20 call activity and the March call spread.

Overall: this is better read as hedging plus selective upside positioning, not a clean directional bearish bet. The critical unknown is whether the large puts were bought or sold.
