Options activity in Medline Inc. intensified on Monday, with total contracts traded reaching 20,588 at 11:01 a.m. New York time, according to exchange data compiled by Bloomberg. The session was defined by an outsized flow of puts versus calls.

Call volume for the session was recorded at 205 contracts, while put volume tallied 20,383 contracts, marking the highest daily put total since December 22, 2025. One specific series accounted for the overwhelming majority of the activity: the July 17, 2026 $35 put, which represented 20,179 contracts of the day’s total. Open interest for that July 17, 2026 $35 put was 847 contracts as of June 26.

Meanwhile, shares of Medline were trading 1.23% higher at $39.35 during the observed intraday snapshot. On the volatility front, the company’s three-month volatility metric declined by 2.40 percentage points to 43.13%. The three-month 90/110 skew also moved lower, falling 3.40 percentage points to -0.66 percentage points.

The session’s footprint shows a pronounced imbalance between put and call participation, concentrated in a single out-of-the-money put strike for July 17, 2026. The open interest figure cited for that strike—847 contracts as of June 26—provides additional context for how much of the recent flow represented new trading versus positions already outstanding.

Observed changes in short-term volatility and skew were downward on the same measurement window, with three-month volatility down 2.40 percentage points and the 90/110 skew down 3.40 percentage points, as reported alongside the volume data.

Risks

  • Concentrated volume in a single option series can create liquidity and pricing distortions in the options market.
  • Rapid shifts in short-term volatility and skew could complicate pricing and hedging for options traders and market makers.
  • High put-heavy flow relative to calls may reflect transient positioning that could unwind quickly, increasing intraday volatility in the underlying equity and related derivatives.
