Generate Investment Ideas

10 min read

Two paths into a fresh idea: a quantitative screen of the market, and an open conversation about the world. Most weeks you will use both.

What you will leave with
  • Two ways to source stock ideas — and when each one is the right tool
  • How to run a value screen of the S&P 500 in one prompt
  • How to read the screener's output without getting lost in numbers
  • How to use natural-language conversation to surface ideas the screener will miss
  • Why the answer is sometimes 'nothing today, check back later'

7.1 Two ways to find an idea

Most professional investors keep two idea pipelines running at once. The first is quantitative: you scan the market for names that look statistically interesting on price and fundamentals. The second is qualitative: you read the news, talk to people, and ask “who benefits from this and who gets hurt?”

Neither alone is enough. Screens surface businesses you would never have thought of on your own. Conversations surface ideas that a numerical filter cannot see yet, because the story is too new. Clarion on Zo gives you a tool for each.

Your job in this stage
Cast a wide net and produce a small list of names worth a second look. You are not yet committing to anything. You are looking.

7.2 Path one: the value screen

The Clarion value screener looks at the S&P 500 (or any list of tickers you give it) and scores each company on eight factors that Buffett-style investors care about — how cheap, how profitable, how productive with capital, how indebted, and whether insiders are buying.

With the clarion-value-screener skill installed and the Clarion Value Screener persona active:

In Zo chat
>Run a value screen of the S&P 500 at my current hurdle rate.
Regime: Orange. Hurdle: 10.5%. Quality bar tightened for the regime.
Screened 503 names. 31 passed the quality threshold. 12 survived the sector cap.

Top names by composite score
1. KO (Consumer Staples) — score 72. Steady cash, modest valuation, insider buying last quarter.
2. JNJ (Health Care) — score 68. Strong margins, moderate growth, low debt.
3. MKC (Consumer Staples) — score 65. Pricing power, slight premium to history.

Watchlist saved to ~/clarion/watchlists/sp500-screen-2026-05-13.md.

Suggest the next step: pick one or two names and run a deeper review.

The output has four pieces worth understanding.

  • The composite score. A number between 0 and 100 that summarizes how a name looks across the eight factors. Higher is better. Anything above 60 is worth a look in a normal regime; tougher regimes raise the bar.
  • The sector cap. The screener will not stack the watchlist with five tech names just because tech ran. No more than a couple of names from the same sector.
  • The watchlist file. The full ranked list is saved to your workspace so you can read it later, share it, or feed it into the next chapter.
  • An empty result is a real answer. If valuations are high and the regime is bad, the screener will return a thin list or none at all. That is the system telling you the opportunity set is weak, not a bug.
You can also screen your own list
If you already have a shortlist of names you are curious about, ask: “screen these tickers: KO, JNJ, MKC, MDT, CL.” The same eight-factor scoring runs over just those names.

7.3 Path two: conversation

Not every idea starts with a number. A new regulation comes through, a commodity moves hard, a competitor announces something, a generational product launches — and you want to find the businesses that benefit or get hurt. A screener cannot answer that yet, because the impact has not shown up in the financials.

This is what the open chat window is for. Treat the AI like a smart colleague who has read the news and knows the public market. The job is not to give you a recommendation. The job is to give you a list of names to investigate.

In Zo chat
>Oil rallied hard this week on the news of tighter sanctions on Russian supply. Which US-listed names should I be looking at as second-order beneficiaries — not the obvious oil majors, but the supply chain, services, infrastructure, or anything else that doesn't show up in the first headline?
Three categories worth a look:

1. Oilfield services. Higher oil prices typically extend drilling cycles. Candidates: SLB, HAL, BKR.
2. Refiners with complex slates. Refiners that can run heavy or sour crude are advantaged when light sweet premiums widen. Candidates: VLO, MPC, PSX.
3. US energy infrastructure. Midstream and LNG-adjacent names benefit from rerouted flow. Candidates: ET, WMB, LNG.

None of these is a recommendation. Three asks for you:
(a) Is the price move already in? Pull up 6-month charts.
(b) Is anything already on the value screen? Cross-check the latest watchlist.
(c) Pick at most two to take into deeper research.

Notice what the AI is doing here. It is not making a buy call. It is producing a structured shortlist with a category for each name and a list of next questions to answer. That is the right shape of output from a conversation at this stage.

A trap to avoid
It is tempting to ask “which of these is the best buy?” The AI will answer if you ask, but at this stage the question is wrong — you have not done the work yet. The right next move is to research, not to rank.

7.4 Where macro fits

The same conversational pattern works for macro events: a Federal Reserve decision, a slowdown in China, a labor shock, an election result. Ask the AI to list the second- and third-order effects on US equities, and to flag the categories that the value screener might be slow to surface.

This is also where the Macro Sentinel persona from the last chapter comes back. Before chasing an idea on a hot news story, ask: what does the current regime say? In a red or danger regime, even good second-order ideas can wait.

7.5 What you end up with

Between the two paths, you should leave this stage with a list of three to ten names worth deeper research. Not fifty. Not one. A list small enough that you can give each name a serious hour in the next chapter, and not so small that you have already decided.

A working pattern
Run the value screen once a month, or after a meaningful drawdown. Keep an open conversation thread for new ideas as the news happens. At the end of the week, compare the two pools: anything that shows up in both is an automatic top-of-list for next week’s research.

Key takeaways

  • Two idea pipelines: a quantitative screen and an open conversation about events. You need both.
  • The value screen returns a small, sector-balanced list of names with a 0-to-100 score and a saved watchlist file.
  • The conversation produces a categorized shortlist of names and a list of next questions, not a recommendation.
  • You are looking, not buying. Three to ten names to research is the right outcome.
  • A thin or empty result in a bad regime is the right answer, not a bug.
