Notable Monday Option Activity: CTVA, MARA, MPW

Marathon Digital (MARA) saw 222,849 option contracts trade today—about 22.3 million underlying shares, roughly 53.7% of its one‑month average daily volume—with heavy activity in the $11 put expiring June 18, 2026 (8,054 contracts, ≈805,400 shares). Medical Properties Trust (MPW) logged 41,089 contracts (≈4.1 million underlying shares, ~51.2% of its one‑month ADV), led by 16,437 contracts in the $5.50 call expiring Nov. 28, 2025 (≈1.6 million shares). Those concentrated, large‑volume flows—representing a material share of each stock’s liquidity—point to significant directional bets or hedging interest (put‑skewed in MARA, call‑skewed in MPW) that could affect near‑term price moves and trading costs.

Analysis

Options flow in Marathon Digital (MARA) and Medical Properties Trust (MPW) was unusually concentrated today: MARA saw 222,849 contracts (~22.3 million underlying shares), equal to about 53.7% of its one‑month ADV of 41.5 million shares, with concentrated activity in the $11 put expiring June 18, 2026 (8,054 contracts, ~805,400 shares). MPW recorded 41,089 contracts (~4.1 million underlying shares), roughly 51.2% of its one‑month ADV of 8.0 million shares, led by the $5.50 call expiring Nov. 28, 2025 (16,437 contracts, ~1.6 million shares). These are material flows relative to liquidity and strike concentration is significant for both tickers.

The pattern is asymmetric: MARA shows put‑skewed activity consistent with directional bearish bets or portfolio hedging, while MPW shows call‑skewed activity consistent with bullish positioning or covered/bullish call structures. Such concentrated option volume can push implied volatility, force dealer delta‑hedging, and create outsized intraday price moves given the market impact score of 0.3 and the mixed/speculative sentiment signals (MARA -0.3, MPW 0.4).

Key uncertainties remain: the public data does not show whether trades were opening or closing or part of multi‑leg strategies. Investors should therefore monitor changes in open interest, intraday IV, and actual stock price response to determine whether flows reflect new directional exposure, hedging, or complex spreads before altering base positions.

Key Decisions for Investors

• Monitor open interest and implied volatility for MARA and MPW over the next 24–72 hours to see if volume reflects net new positions or mere roll/close activity
• Given concentrated $11 put flow, consider trimming or hedging directional MARA exposure (e.g., buy protective puts or reduce position size) until intention behind flows is clearer
