VOO: Options Signal a Shift as the Index Finds a Floor

VOO enters the first week of November having recovered slightly from last week's tech-driven selloff, but the most striking development is in options, where the put/call ratio has collapsed to its lowest reading of the past year.

The options market has undergone a dramatic repositioning over the past 48 hours. The put/call ratio fell to 0.95 on Tuesday, almost three standard deviations below its 20-day mean of 3.88. That mean itself tells the story: for most of October, the ratio sat persistently above 4.0, reflecting heavy demand for downside protection as AI valuation concerns weighed on tech. The 52-week high of 4.47 was posted just two weeks ago. Now the ratio has dropped to its 52-week low of 0.57 range, a swing that suggests active call buying or put unwinding at a scale that is unusual for a broad passive vehicle. Whether this reflects tactical bullishness, options book rebalancing, or expiry mechanics is not clear from the data alone. What is clear is that the options market looks nothing like it did a week ago.

The price action is consistent with a tentative floor. VOO closed at $693.54 on Tuesday, up 0.3% on the day but still down 2.0% on the week and 2.0% on the month. That confirms the picture from last week's stock report: the ETF remains below the $715 level that proved significant in October, and the Alphabet-led selloff has not been fully reversed. The one-day recovery is modest. Borrow conditions remain completely irrelevant as a signal for a fund this size. Availability is essentially uncapped, the lending pool holds nearly 1 billion shares available, and the cost to borrow is 0.33%, down 11% on the week. Short interest, at 0.40% of the float, is unchanged from last week's reading and carries no directional information.

The ORTEX short score has drifted slightly higher to 26.1, but remains in the lower third of its range and has moved less than a point over the past week. That is consistent with what has been true since October: for VOO, the short-selling data is background noise. The ETF's $1.7 trillion market cap and near-infinite lending pool mean that any signal worth watching comes from elsewhere.

The key question for the week ahead is whether the sharp reversal in the put/call ratio represents genuine sentiment turning or simply a technical artefact of the November options cycle. The divergence between October's sustained defensive positioning and this week's sudden call-side tilt is large enough to watch closely as the November expiry approaches.
