How are SO straddle max profit and max loss calculated?

Upside max profit is unbounded; downside max profit is bounded at the strike minus the combined call plus put debit (reached at zero). Max loss equals the combined debit times 100 (reached when the underlying pins to the strike). Two breakevens at strike plus debit and strike minus debit. For the SO straddle priced from the August 14, 2026 end-of-day chain at a 30-day expiry (ATM IV 16.04%), the computed maximum profit is unbounded per contract and the computed maximum loss is -$284.25 per contract. Live intraday quotes will differ as the chain moves through the trading session.

What is the breakeven for a SO straddle?

The breakeven for the SO straddle priced on this page is roughly $89.73 and $96.28 at expiration, derived from the August 14, 2026 end-of-day chain's premiums. Breakeven is the underlying price at which the strategy's P&L crosses zero ignoring transaction costs and assignment risk. The SO market-implied 1-standard-deviation expected move in the same options snapshot is approximately 4.60%; if the move sits well outside the breakeven distance, the structure's risk-reward becomes correspondingly tighter.

How does current SO implied volatility affect this straddle?

SO ATM IV is at 16.04% with IV rank near 20.27%, which is on the low end of its 1-year range. Premium-buying structures (long call, long put, debit spreads) are relatively cheap in this regime; premium-selling structures collect less credit per unit risk.

Complementing its power business, it distributes natural gas in Illinois, Georgia, Virginia, and Tennessee, while also offering gas marketing services, wholesale gas services, and managing gas pipeline investments. Its extensive portfolio of generating assets includes 30 hydroelectric, 24 fossil fuel, three nuclear, 13 combined cycle/cogeneration, 45 solar, 15 wind, one fuel cell, and four battery storage facilities.

SO (The Southern Company) trades in the Utilities sector, specifically Regulated Electric, with a market capitalization of approximately $106.43B, a trailing P/E of 22.59, a beta of 0.33 versus the broader market, a 52-week range of 83.8-100.84, average daily share volume of 5.6M, a public-listing history dating back to 1981, approximately 30K full-time employees. These structural characteristics shape how SO stock options price implied volatility around earnings windows, capital events, and macro-driven sector rotations.

A beta of 0.33 indicates SO has historically moved less than the broader market, dampening realized volatility and producing tighter expected-move bands per unit of dollar exposure. SO pays a dividend, which adjusts put-call parity and shifts the ex-dividend pricing across the listed chain.

What is a straddle on SO?

A long straddle buys an ATM call and an ATM put at the same strike, profiting from a large move in either direction; max loss equals the combined debit when the underlying pins to the strike at expiration.

SO snapshot

As of August 14, 2026, spot at $93.03, ATM IV 16.04%, IV rank 20.27%, expected move 4.60%. The straddle on SO below is built from the August 14, 2026 end-of-day chain, with strikes snapped to listed contracts and premiums pulled from the bid/ask midpoint at a 28-day expiry.

Why this straddle structure on SO specifically: SO IV at 16.04% is on the cheap side of its 1-year range, which favors premium-buying structures like a SO straddle, with a market-implied 1-standard-deviation move of approximately 4.60% (roughly $4.28 on the underlying). The 28-day window matched to the front-month expiry keeps theta exposure bounded while still capturing the post-snapshot move; longer-dated SO expiries trade a higher absolute premium for lower per-day decay. Position sizing on SO should anchor to the underlying notional of $93.03 per share and to the trader's directional view on SO stock.

SO straddle setup

The SO straddle below is built from the August 14, 2026 end-of-day chain, with each option leg priced at the bid/ask midpoint of its listed strike. With SO at $93.03 on that close, the first option leg uses a $93.00 strike; additional legs (when the strategy has them) anchor to spot-relative offsets. Premiums come from the bid/ask midpoint on the listed SO chain at a 28-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 SO shares for the stock leg in covered calls and collars).

Action	Type	Strike / Basis	Premium (est)
Buy 1	Call	$93.00	$1.45
Buy 1	Put	$93.00	$1.83

SO straddle risk and reward

Net Premium / Debit: -$327.50
Max Profit (per contract): Unbounded
Max Loss (per contract): -$284.25

Upside max profit is unbounded; downside max profit is bounded at the strike minus the combined call plus put debit (reached at zero). Max loss equals the combined debit times 100 (reached when the underlying pins to the strike). Two breakevens at strike plus debit and strike minus debit.

When traders use straddle on SO

Straddles on SO are pure-volatility plays that profit from large moves in either direction; traders typically buy SO straddles ahead of earnings, FDA decisions, or other catalysts where the realized move is expected to exceed the implied move priced into the chain.

SO thesis for this straddle

The market-implied 1-standard-deviation range for SO extends from approximately $88.75 on the downside to $97.31 on the upside. A SO long straddle is a pure-volatility play: it profits when the underlying moves far enough from the strike in either direction to overcome the combined call plus put debit, regardless of direction. Current SO IV rank near 20.27% 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 SO at 16.04%. As a Utilities name, SO options can move on sector-level news flow (peer earnings, regulatory updates, industry-specific macro data) in addition to SO-specific events.

SO straddle positions are structurally neutral / high-volatility (long premium); 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. SO positions also carry Utilities sector concentration risk; news flow inside the sector (peer earnings, regulatory shifts, supply-chain headlines) can move SO alongside the broader basket even when SO-specific fundamentals are unchanged. Always rebuild the position from current SO chain quotes before placing a trade.
