As of 2026-07-29. Framework v1.5.1. Tier-2 memo, cluster member (data & dev infrastructure).
Cluster analysis: reports/clusters/Data_Dev_Infrastructure_Cluster_2026-07-29.md
This memo issues no position verdict. The book decides.
Spot $320.98. 252-day volatility 74.4%. Jan-2027 implied volatility 74%.
No position verdict is issued. What follows is the construction that would express the analysis, sized and risk-managed, for the book to accept or decline.
| Implied-path result | PASS — requires 12.6% CAGR at a 8.0x exit vs 25.2% demonstrated (+12.7pp) |
| 12-month target | $436.92, +36.1% |
| Own-history percentile | 21th of the post-2023-01 window |
| Required terminal EBIT margin @20x | 23.6% vs 17.2% earned today before SBC |
| Committed forward-12m revenue | 29.7% of TTM revenue — the LOWEST in the cluster, and a floor: the practical expedient omits contracts of 12 months or less |
| NRR disclosure form | 121% (Apr-26) — exact value, but NO prior-year comparative in the filing. Reader must build the series. |
Equity: PASS. Market capitalisation $25.84bn. Sufficient for the intended size and a plausible exit.
The chain was pulled first, as the Liquidity Criteria requires, and it does not support one.
Full chain as pulled (Jan-2027 calls): Jan-2027 $320 call: OI 477, bid $63.35 x46 / ask $71.36 x26 — a 12.6% spread with 46 bid and 26 offered. $340 OI 324 (x34/x41); $360 OI 367 (bid x8 / ask x11); $400 OI 359. IV 73-75%. WEAKEST quoted depth in the cluster. Size to quoted depth, not to open interest. The equity is the appropriate vehicle.
Verdict on fillability: a defined-risk spread is NOT recommended here. A 12.6% bid-ask spread on the at-the-money strike, with quoted size in the tens of contracts and one strike offering only eleven contracts, means entry slippage would consume a material share of any expected edge before the thesis had a chance to work. This is not the HCA failure — the chain exists and trades — but it is thin enough that the position must be expressed in the equity. Recording this explicitly, because a vehicle that cannot be filled at size is not a vehicle, and the failure mode is to propose the structure without checking.
Inverse-volatility sizing is the active protection on the Downside Criteria, which is MEASURED and therefore constrains nothing directly. 252-day volatility is 74.4%, so this name sizes down relative to a 30%-volatility position by a factor of roughly 2.5x.
The specific sizing decision belongs to portfolio-book, not to this memo. What this memo supplies:
| Sizing input | Value |
|---|---|
| 252-day volatility | 74.4% |
| Realised drawdown, Oct/Nov-2025 to Apr-2026 | see the cluster document — every name in this cohort fell 19–60% |
| Bear case, most probable | Net ARR expansion to 108%, multiple to post-2024 min of 6.3x: $224.00, -30% |
| Correlation warning | All five cluster names moved together: −19% to −60% into April 2026, then +34% to +88% in May 2026 alone. These are not five independent positions. A book holding more than one is holding one factor. |
The correlation point is the material sizing constraint here and it applies to the whole cluster, not to this name. Sizing five names at a single-name limit each would produce a single factor bet at five times the intended exposure.
12-1 momentum, assessed cross-sectionally against the cluster and the broad universe:
| Name | Jul-2025 | Jun-2026 | 12-1 momentum |
|---|---|---|---|
| DDOG | $140 | $260 | +85.7% |
| MDB | $238 | $336 | +41.2% |
| SNOW | $224 | $254 | +13.4% |
| GTLB | $44 | $31 | −29.5% |
| TEAM | $192 | $78 | −59.4% |
Momentum governs when to enter a position the thesis already justifies — never whether. Its type is MEASURED and it has been silently promoted to blocking before in this framework's record; it is not promoted here.
The specific timing caveat for the whole cluster: the entire cohort re-rated between +34% and +88% in May 2026 alone, after a six-month drawdown. Any 12-1 momentum reading on these names is dominated by one month. A 12-month signal composed of one month is a fragile signal, and that applies to DDOG's +85.7% as much as to TEAM's −59.4%.
| Trigger | Where it appears | Timing |
|---|---|---|
| 121% (Apr-26) — exact value, but NO prior-year comparative in the filing deteriorating | quarterly filing | late August 2026 |
| RPO growth falling below revenue growth | quarterly filing — $1,458.6m, +88.4% YoY (fastest in cluster), 53% inside 12 months, 46% in 13-36 months | late August 2026 |
| Gross margin compression accelerating | quarterly income statement | late August 2026 |
| Buyback paused or reduced | cash flow statement, financing section | late August 2026 |
| SBC as a share of revenue rising | cash flow statement | late August 2026 |
The invalidation-gap exit is governed by portfolio-book, not here. What this memo establishes is which
line to read, and for this name the answer is in §2 of the research document and in the RPO and retention rows
above.
The bear case and the nearest catalyst are frequently the same event. Q2 FY2027 (quarter ending 2026-07-31) is expected late August 2026, and it is the print that resolves the invalidation triggers above. A structure with an expiry before that date carries the risk without the resolution; a structure expiring long after it pays theta through the resolution. Jan-2027 is chosen because it spans two full reporting cycles, not because it is the cheapest expiry.
And the largest construction risk is not in this name — it is in the cluster. See §3.
