The memo issues no position verdict. This section establishes what is investable and at what size — the liquidity and vehicle facts the book needs in order to decide. Every contract below was pulled live from the Alpaca options chain on 2026-07-29 with quoted size, not assumed.

1. Liquidity — Liquidity Criteria (BINDING): PASS


63-day average daily dollar volume	$594.3m
Median shares/day (63d)	2,070,668
Shares outstanding	107,453,003
Free float (SEC `EntityPublicFloat`)	~$17.7bn
252-day realised volatility	53.8%
63-day realised volatility	59.0%
52-week range	$174.73 – $318.25 (now −36.5% from the high)

A $10m position is ~1.7% of one day's dollar volume and exits inside a single session at any plausible size for this book. Liquidity is not a constraint. Size is constrained by volatility, not by tradability — at 53.8% realised vol, inverse-vol sizing puts this in the lower third of the book's position sizes.

2. Options chain — pulled, verified, and deep

Jan-2027 (2027-01-15, 170 days) chain, Alpaca v1beta1/options/snapshots, 2026-07-29. This is the expiry that spans the whole 12-month target window and contains Q2'26, Q3'26, Q4'26 and Q1'27 results.

Implied vol across the entire chain is 67–72%, against 53.8% realised. IV/RV ≈ 1.27. Options here are expensive in absolute and relative terms; any long-premium structure starts ~27% behind on carry.

The HCA failure mode does not apply here. Maximum open interest across the March-2027 HCA chain was 18 contracts; FSLR's Jan-2027 chain has five strikes above 4,500 OI with two-sided quoted size in the hundreds. Every structure below is fillable at institutional size.

3. Vehicles, if the book wants exposure

Presented as constructions with live economics, not as a recommendation.

3.1 Long exposure — common stock, not options

At IV/RV 1.27 a long call is a poor way to express the base case. The Jan-27 $240 call costs $26.55 (ask) = 13.1% of spot for 170 days of a 0.46-delta claim; the base-case target of $235 leaves it worthless at expiry. The base case (+16.0% to $235) is not a call-buyer's case — it is a stock case.

Vehicle: common stock.
Entry: $202.59 (memo price). Invalidation on thesis, not on price: a bookings figure that re-accelerates above ~5 GW/quarter, or a reinstated GAAP EPS guide, would invalidate the negative read on §5 of the Research doc.
Price invalidation: the 52-week low of $174.73 (−13.7%) is the level at which the market is no longer disagreeing with the downside case.
Sizing: inverse-volatility, on 53.8% realised. This is a high-vol name and sizes down automatically. That is the active protection for the MEASURED Downside Criteria, since the downside case is logged rather than binding.

3.2 Financing the long with downside sold — the IV/RV trade

If the book wants exposure at all, the 67–72% IV is worth harvesting rather than paying.

Sell Jan-27 $150 put @ $10.87 bid, OI 10,070, bid size 323.
Premium $10.87 on a $150 strike = 7.2% for 170 days; effective entry $139.13 (−31.3% from spot) if assigned; delta −0.181.
$139.13 is below the $145 bear-case target and comfortably below the $100–130 permanent-loss band's upper bound — i.e. this structure is short the volatility, not short the tail. The tail is where the analysis says the risk actually is, so this is a premium trade with a real left tail and must be sized as such.

3.3 Expressing the downside — defined risk

Buy Jan-27 $180 put @ $24.82 ask, OI 9,025, quoted size 243×206, delta −0.302.
Sell Jan-27 $150 put @ $10.87 bid, OI 10,070.
Net debit ~$13.95. Max value $30.00. Payoff ratio 2.15:1. Breakeven $166.05 (−18.0%). Max value is reached at $150, inside the bear-case target ($145) and above the permanent-loss band ($100–130).
The debit is 6.9% of spot for 170 days at IV 67.6% against 53.8% realised — you are paying a 27% vol premium for a view whose first clean catalyst (Q3 2026 results, the first quarter entirely after the ~2026-07-04 safe-harbour deadline) does not report until ~late October 2026, well inside this expiry. The catalyst timing works; the carry does not.

3.4 What is not investable

Long calls at any strike (§3.1 — IV/RV and the base-case target both argue against).
Anything with a target date dependent on USITC 337-TA-1494. The target date is unknown and was not estimated, so no structure may be sized to it.

4. Position and risk parameters, if a position is opened

Parameter	Value	Basis
Realised vol (252d)	53.8%	inverse-vol sizing input
Beta	not computed in this run	recorded as a gap; not estimated
Price invalidation	$174.73	52-week low
Thesis invalidation (long)	quarterly gross bookings > ~5 GW, or GAAP EPS guidance reinstated	either would falsify §4.4 and §5.2 of the Research doc
Thesis invalidation (short)	a USITC general exclusion order in 337-TA-1494	would materially change US module pricing
First hard catalyst	Q2 2026 results — date not announced by the company	four-year cadence 2022-07-28 / 2023-07-27 / 2024-07-30 / 2025-07-31
First clean read on the policy cliff	Q3 2026 results, ~late Oct 2026	first quarter falling entirely after ~2026-07-04

5. Ledger entry

No trade is recommended by this memo, so no entry is appended to trade_recommendations.jsonl. The bear case, its probability (25%) and its named cause are logged in the Criteria scorecard and the manifest for Brier scoring under the Downside Criteria promotion path.

Generated from each name's analysis.json. Figures are research output, not investment advice. Gaps are shown as “—” rather than filled: a missing input is recorded as indeterminate, never estimated.
