Analyzes a portfolio's observable and hidden risk factors, clusters them and keeps the analysis updated.

The prompt

✦GPT-6 Astra
1Analyze the attached portfolio's risk factors in two layers.
2
3First, identify conventional and relatively observable factors, including:
4
5Interest rates and discount rates
6Economic growth and recession
7Consumer spending
8Credit availability and refinancing
9Inflation and labor costs
10Commodity and energy prices
11Foreign exchange rates
12Housing and commercial-real-estate activity
13Government spending and regulation
14Industry capital-expenditure cycles
15Equity-market liquidity and investor risk appetite
16Geography, customers, suppliers, and end markets
17Technological disruption
18Competitive intensity
19
20Second, search creatively for less obvious common exposures. Look for companies from apparently unrelated industries that depend on:
21
22The same customer group or source of customer funding
23The same industry’s capital-expenditure budget
24Shared suppliers, infrastructure, distribution channels, or technology platforms
25Electricity, cloud computing, telecommunications, payment rails, cybersecurity, or electronic connectivity
26Continuously available and inexpensive financing
27Government licenses, reimbursement, subsidies, contracts, or emergency-policy support
28Similar investor ownership, market liquidity, index inclusion, or susceptibility to forced selling
29The same assumptions about consumer behavior, demographics, globalization, or institutional stability
30Second- and third-order economic relationships
31A single external event that could simultaneously affect otherwise unrelated businesses
32Government intervention that might protect some assets or companies while excluding others
33
34Be imaginative but disciplined. A creative factor must have a coherent causal mechanism. Do not manufacture connections merely because two securities have historically moved together.
35
36For every material factor or cluster, explain:
37
38Which portfolio positions are exposed?
39What specifically connects them?
40What event or change would activate the factor?
41How would the factor travel through each business?
42Would it affect fundamentals, valuation, financing, market liquidity, or some combination?
43Would the damage likely be temporary or potentially permanent?
44How confident are you that the connection is economically real?
45Could a reasonable investor have identified and acted upon the factor beforehand?
46Why might the proposed grouping be misleading or overstated?
47
48Pay particular attention to companies classified in different industries that ultimately depend on the same economic engine.
49
50Recognize the limitations of factor analysis. After a crisis, it is always possible to redraw boundaries around the affected companies and give their shared exposure a new name. Distinguish among:
51
52Established factors that were identifiable and actionable beforehand
53Hidden factors that could have been identified through deeper analysis
54Background dependencies that are real but nearly impossible to avoid
55Factors whose importance could not reasonably have been understood before an unprecedented event
56Retrospective narratives that explain the past but offer little practical foresight
57
58Do not assume every shared characteristic constitutes a useful risk factor. A useful factor requires a plausible mechanism through which multiple holdings could be affected together.
59
60Coverage and exclusions:
61
62Do not stop the analysis because one or more securities cannot be adequately researched. Complete the analysis using every position for which sufficient information is available.
63
64Classify every portfolio position as:
65
66Fully analyzed
67Partially analyzed
68Excluded
69
70Mark a position partially analyzed or excluded when you cannot identify the security confidently, cannot access reliable information, do not adequately understand its business, lack necessary portfolio or thesis information, encounter conflicting information, or cannot establish its risk exposures without speculation.
71
72For every partially analyzed or excluded position, disclose:
73
74Company name and ticker
75Portfolio weight, if available
76Whether it was partially analyzed or excluded
77The precise reason for the limitation
78Which portions could and could not be analyzed
79What information would be needed to complete the analysis
80How the omission could distort the portfolio-level conclusions
81
82Calculate the total portfolio weight that was fully analyzed, partially analyzed, and excluded. Never describe the work as covering the entire portfolio when material positions were omitted.
83
84Do not invent a company’s business model or exposures to achieve complete coverage. Include tentative conclusions only when clearly labeled as low confidence.
85
86Continue the analysis without waiting for clarification. Request missing information at the end so omitted positions can be incorporated into a later update.
87
88Output requirements:
89
90Present the results in two layers.
91
92Begin with an intuitive executive summary written in clear, conversational language. It must be understandable without reading the supporting tables. Avoid excessive jargon and long lists of immaterial observations.
93
94The executive summary should explain:
95
96The three to five most important risk clusters
97Which companies belong to each cluster and what connects them
98Where the portfolio is more concentrated than it initially appears
99Which apparent concentrations are probably less serious than they look
100The most important hidden or surprising connection
101Which risks are conventional and readily identifiable
102Which risks are more creative, uncertain, or dependent on unusual circumstances
103The percentage of the portfolio included in the analysis
104Any material securities partially analyzed or excluded
105The bottom-line conclusion about how the portfolio is diversified
106
107Explain each cluster causally and intuitively. Do not merely name a factor such as “interest-rate risk.” Explain how it travels through the businesses and why it could cause the positions to struggle simultaneously.
108
109Prioritize factors according to the portfolio weight exposed, potential severity, and confidence in the connection.
110
111After the executive summary, provide:
112
113A. Portfolio coverage and exclusions
114B. Major identifiable risk factors
115C. Cross-industry risk clusters
116D. Hidden or unconventional shared exposures
117E. Imaginative but plausible stress scenarios
118F. Detailed position-by-factor analysis
119G. Blind spots and information needed
120For each important cluster, show:
121Shared factor or dependency
122Positions exposed
123Approximate portfolio weight exposed
124Transmission mechanism
125Potential severity
126
127Confidence in the connection
128
129Ex-ante identifiability
130Reasons the grouping could be overstated
131Use current primary sources such as regulatory filings, earnings materials, and company investor presentations. Cite material factual claims.
132Do not provide position-sizing, trading, or portfolio-reconstruction recommendations unless specifically requested.
133Maintain this as an ongoing analysis. When the portfolio changes, update the clusters, exposed portfolio weights, coverage assessment, and overall conclusions rather than starting from scratch.
