| description | Apply Howard Marks' Second Level Thinking framework to investment decisions. Use this skill whenever the user is analyzing an investment opportunity, evaluating a trade thesis, stress-testing a conviction, or asking whether a stock/asset/market is actually as attractive as it looks. Also trigger when the user wants to challenge their own reasoning ("am I just following the crowd?"), wants to identify what the market is mispricing, is debating whether a consensus view is already fully reflected in price, or asks about risk/reward asymmetry, market cycles, or contrarian positioning. The skill channels Marks' philosophy: superior returns require being different AND right — and that starts with understanding what everyone already believes.

Second Level Thinking — Howard Marks Framework
The market is a discounting machine. Outperformance comes from being right about something the
market is wrong about. Second-level thinking asks: What does the current price imply? Is that
belief justified? And what is everyone missing?
Research First
Do the work before the framework. Assertions without data are opinions.
Search for: SEC filings (10-K, 10-Q), earnings transcripts, capex disclosures, ROIC trends,
interconnection queue data (FERC/EIA), fab lead times, labor market stats (BLS), and comparable
historical cycles (telecom 1990s, shale, cloud infrastructure). Cite sources. When data is
unavailable, say so — that's more valuable than a fabricated number.
The Seven Stages
1 — Decode the Consensus
Reverse-engineer the price. If the current valuation is rational, what growth, margin, and terminal
assumptions must hold? Back it with data: consensus EPS, analyst targets, implied revenue growth.
Identify prevailing sentiment — crowded long or unloved?
2 — The Second-Level Challenge
Interrogate the consensus through three lenses:
- Information asymmetry: Data or channel checks the market hasn't weighted correctly
- Analytical asymmetry: Different unit economics, non-consensus moat view, misunderstood costs
- Behavioral asymmetry: Extrapolation bias, loss aversion, narrative capture, neglect, recency
For each: is this a real edge, or a story the investor tells themselves?
3 — Supply/Demand Economics
The stage most analyses skip. Demand can be real and the investment still bad if the market ignores
what it costs to supply that demand.
Demand reality check: Validate TAM bottom-up (unit economics × customers, not "X% of $Y
trillion"). Find S-curve penetration data. Check pricing power under customer concentration. Assess
substitution timeline — the consensus systematically underestimates arrival speed.
Supply-side bottlenecks: The market prices revenue without pricing the friction to produce it.
- Capex intensity: Get capex-to-revenue ratios from 10-K filings. What's the incremental capex
per $1B of new revenue? Is it rising?
- Physical lead times: Power interconnection queues (3-7 years, per FERC data), fab construction
(3-5 years, $10-20B+), warehouse/logistics timelines. Find the actual queue data.
- Human capital: Specialized talent (AI researchers, power engineers, fab technicians) doesn't
scale on demand. Compare historical hiring rates to growth plan requirements.
- Supply chain: Single-source dependencies, geopolitical concentration, regulatory queues create
hard growth ceilings.
The question isn't whether growth is possible — it's how long it takes and what it costs. A
five-year buildout priced as a two-year story is a valuation risk.
Diminishing marginal returns: Pull ROIC/ROIIC trends over 3-5 years. Is ROIIC declining? Compare
ROIC to cost of capital — growth that earns below WACC destroys value. Watch for the "crowding in"
dynamic: more capital chasing the same resources drives up input costs and erodes margins. Frame as:
"ROIIC declined from X% to Y%, suggesting the next investment phase generates lower returns than
priced in."
4 — Risk Asymmetry
Map the full probability distribution, not just upside/downside:
- Bull / Base / Bear cases with explicit probability weights
- Feed supply-side findings from Stage 3 into scenarios — "capex overrun + timeline delay" is a
more credible bear case than generic "things go wrong"
- Use historical base rates for megaproject cost/schedule overruns (Flyvbjerg's database, McKinsey)
The Marks question: Is the ratio of potential gain to potential loss, weighted by probability,
actually attractive? More upside than downside in dollar terms can still be a bad bet if the bear
case is probable or catastrophic.
5 — Cycle Positioning
Where are we in the macro/credit cycle? This determines starting price and error-correction time.
- Late-cycle (expensive, tight spreads, euphoria) vs. early-cycle (cheap, stressed, fear)
- Marks' pendulum: greed end (play defense) or fear end (get aggressive)
- Capital abundance compresses expected returns; scarcity creates opportunities
- How does the cycle affect this specific thesis?
6 — The Structural Edge Test
The hardest question: Why do you have an edge here?
Three real edges exist: informational (you know something legal the market doesn't), analytical
(you've modeled it better), behavioral (you can stay rational when others can't). If the honest
answer is "no clear edge" — don't expect outperformance.
7 — The Verdict
Synthesize into a clear conclusion:
- Consensus view: One sentence
- Second-level view: What the market gets wrong and why
- Supply/demand finding: The key physical or economic friction being underweighted
- Edge: Informational / analytical / behavioral — specific
- Risk/reward: Probability-weighted, grounded in Stage 3 scenarios
- Cycle context: How conditions affect required margin of safety
- Conviction: High / Medium / Low — and what moves it
- Thesis-breakers: Key variables to monitor
Output Format
Structured analysis across all seven stages. Use numbers, cite sources, name biases explicitly. No
"on one hand / on the other hand" hedging. Channel Marks: skeptical, rigorous, honest about
uncertainty. If the user hasn't shared enough, ask one focused question before proceeding.
Failure Modes (First-Level Thinking in Disguise)
- "Obviously undervalued" — If obvious, it's already priced in
- Quality ≠ investability — Great business at terrible price = terrible investment
- Demand ≠ returns — A $100B market can produce sub-WACC returns if capex is too high
- Flat ROIC projection — Projecting today's returns on tomorrow's larger capital base without
evidence returns won't compress
- "Temporary" constraints — Power grids need 10-year cycles, talent pools are genuinely thin,
permit queues aren't shrinking. Test with data before accepting the "temporary" framing
- Asserting without citing — All quantitative claims need a specific source
- Ignoring the cycle — No thesis exists in a vacuum
- Symmetric framing — "50/50 upside/downside" without probability weighting isn't analysis
