TXNM (TXNM Energy, Inc.) trades in the Utilities sector, specifically Regulated Electric, with a market capitalization of approximately $6.57B, a trailing P/E of 37.63, a beta of 0.17 versus the broader market, a 52-week range of 52.59-59.52, average daily share volume of 1.4M, a public-listing history dating back to 1973, approximately 2K full-time employees. These structural characteristics shape how TXNM stock options price implied volatility around earnings windows, capital events, and macro-driven sector rotations.
A beta of 0.17 indicates TXNM has historically moved less than the broader market, dampening realized volatility and producing tighter expected-move bands per unit of dollar exposure. The trailing P/E of 37.63 is on the rich side, which tends to correlate with higher earnings-window IV expansion as the market debates whether forward growth supports the multiple. TXNM pays a dividend, which adjusts put-call parity and shifts the ex-dividend pricing across the listed chain.
What is a cash-secured put on TXNM?
A cash-secured put sells an out-of-the-money put while holding cash equal to the strike-times-100 obligation, keeping the premium when the underlying stays above the strike.
Current TXNM snapshot
As of May 15, 2026, spot at $59.22, ATM IV 9.70%, IV rank 3.26%, expected move 2.78%. The cash-secured put on TXNM below is built from the same end-of-day chain, with strikes snapped to listed contracts and premiums pulled from the bid/ask midpoint at a 34-day expiry.
Why this cash-secured put structure on TXNM specifically: TXNM IV at 9.70% is on the cheap side of its 1-year range, which means a premium-selling TXNM cash-secured put collects less credit per unit of strike-width risk, with a market-implied 1-standard-deviation move of approximately 2.78% (roughly $1.65 on the underlying). The 34-day window matched to the front-month expiry keeps theta exposure bounded while still capturing the post-snapshot move; longer-dated TXNM expiries trade a higher absolute premium for lower per-day decay. Position sizing on TXNM should anchor to the underlying notional of $59.22 per share and to the trader's directional view on TXNM stock.
TXNM cash-secured put setup
The TXNM cash-secured put below is built from the end-of-day chain, with each option leg priced at the bid/ask midpoint of its listed strike. With TXNM near $59.22, the first option leg uses a $56.26 strike; additional legs (when the strategy has them) anchor to spot-relative offsets. Premiums come from the bid/ask midpoint on the listed TXNM chain at a 34-day expiry; the cross-strike IV skew is reflected directly in the per-leg values rather than approximated. Quantity sizing assumes one contract per option leg (or 100 TXNM shares for the stock leg in covered calls and collars).

TXNM thesis for this cash-secured put
The market-implied 1-standard-deviation range for TXNM extends from approximately $57.57 on the downside to $60.87 on the upside. A TXNM cash-secured put lets a trader earn premium while waiting to acquire TXNM at the strike price; the strategy is most attractive when the trader is comfortable holding the underlying at that level and IV is rich enough to compensate for the assignment risk. Current TXNM IV rank near 3.26% sits in the lower third of its 1-year distribution, where IV often re-expands toward the mean; this favors premium-buying structures and disadvantages premium-selling structures on TXNM at 9.70%. As a Utilities name, TXNM options can move on sector-level news flow (peer earnings, regulatory updates, industry-specific macro data) in addition to TXNM-specific events.
TXNM cash-secured put positions are structurally neutral to slightly bullish; the modeled P&L assumes European-style exercise at expiration and ignores early assignment, transaction costs, dividends paid before expiry on the stock leg (when present), and the bid-ask spread on the listed chain. TXNM positions also carry Utilities sector concentration risk; news flow inside the sector (peer earnings, regulatory shifts, supply-chain headlines) can move TXNM alongside the broader basket even when TXNM-specific fundamentals are unchanged. Short-premium structures like a cash-secured put on TXNM carry tail risk when realized volatility exceeds the implied move; review historical TXNM earnings reactions and macro stress periods before sizing. Always rebuild the position from current TXNM chain quotes before placing a trade.
