• Portfolio Construction: Diversified across small firms
Peter Lynch
• Orientation: Hybrid (growth + value)
• Time Horizon: Long-term
• Asset Focus: Equities (all categories)
• Valuation Lens: GARP, special situations, cyclicals
• Risk Approach: Pragmatic
• Decision Drivers: Company fundamentals, “invest in what you know”
• Portfolio Construction: Broadly diversified (hundreds of stocks)
Q2:
It would be Peter Lynch for the following reasons
• Lynch’s “invest in what you know” principle helps inspire ordinary investors like myself to leverage everyday observations & then build from there.
• He blended growth and value (GARP: Growth At a Reasonable Price), which makes his approach adaptable across market cycles.
• Lynch ran a massively diversified portfolio (hundreds of stocks) yet still delivered outsized returns. They way he hustled to run such a big PF is an inspiration by itself.
• From this book , I learnt that
o Less than 5 percent of Lynch's trades are bigger than 10,000 shares.
o in a matter of weeks had sunk 3 percent of Magellan's capital in LaQuinta
o Insider tips never worked, M&A Rumours never worked (i.e) "the sizzle, not the steak," as he says — and again he will bite, and again he will lose.
o Lynch looks particularly at unit growth, even more than earnings growth
o "The very best way to make money in a market is in a small growth company that has been profitable for a couple of years and simply goes on growing" says Lynch.
o The stock Lynch says he most wants to avoid is the hottest stock in the hottest industry — the one that gets the most favourable publicity, that every investor is told about by other investors
o His dream, he says, somewhat surprisingly, is the growth company in a slow-growth industry: You know something has to be profoundly right about the situation
o "I don't care whether the stocks are going up, down, sideways." There is, however, one exception: catching the turn. That maneuver attracts Lynch strongly
o "if a company has a good balance sheet when I buy it, that gives me a big edge. If it doesn't turn around I can perhaps lose a third of what I invest. But if it does turn around, then I can do very well indeed."
Q3: Michael Steinhardt represents the super trader’s archetype.. His mantra was “you never make big money without getting in the way of danger.” He deliberately positioned himself where volatility and risk were highest, believing that’s where outsized gains could be carved.
Love your insight about "His dream, he says, somewhat surprisingly, is the growth company in a slow-growth industry: You know something has to be profoundly right about the situation." Can be so true (e.g. ORLY, ROST, ECL, etc)
It's a tough call among Carret, Wanger and Michaelis, but I like Michaelis the best. His approach was business-focused, low risk, practical, and tolerant of lagging the market averages. He was patient. Many of his criteria for identifying good companies reminded one of Fisher. He didn't rely on rigid formulas but built on the sustainable 'whys' of success. I like his method of monitoring a group of interesting companies, even if they weren't currently at the right price, so that he was prepared to act when opportunities arose. His approach has aspects I can model.
Q3:
Michael Steinhardt was my least favorite, followed by Soros and most of the other traders/speculators. Trading at the frequency that he did ('innumerable transactions') seems like a consuming, breakneck way to make money, leaving little room for other meaningful activities. Using borrowed money as leverage is not appealing to me, and trying to make profit by shorting failing companies feels like the opposite of investing (building/growing something). He didn't conduct most of his own research but paid others to do it for him, and he didn't seem to take an interest in understanding businesses. Although he did have some good tips, there's not much in his approach I want to model.
Q4:
I had two variations for idea generation based on Wanger. In one I used an industry I’m familiar with and the other I left broad. I added the odds of the catalyst happening to see what the AI put weight on (it leaned optimistic on all of them, so that might not really be of value).
Use Wanger's approach of looking for companies that benefit from changing trends. Identify the changing trends in NAME OF INDUSTRY. For each relevant trend, compile a list of promising companies that fill support roles.
Or
Identify unrelated macro or micro trends across demographics, consumer behavior, logistics, energy systems, materials science, healthcare, climate adaptation, regulatory shifts, digital infrastructure, and global economic realignment. AI may be included as only one trend.
For each trend:
1. Explain the trend in 2–4 sentences, and why or why not it is durable over a multi‑year horizon.
2. Identify 3–5 companies that play support, enabling, or infrastructure roles (not the obvious headline disruptors).
3. For each company, provide a structured assessment with:
- Investment Thesis
- Bear Case Catalysts, Bull Case Catalysts and Odd of each in next 5 yrs
Prioritize companies with:
• strong balance sheets
• durable competitive advantages
• multi‑year growth potential
• low hype exposure
• business models that benefit from the trend but do not depend on perfect execution
Avoid herd behavior by excluding:
• over‑crowded AI names (unless they solidly check all the boxes)
I think the idea of being mindful of change, especially if it's a change in secular trends, is very important. Different investors approach this differently (e.g. try to avoid the losers vs. picking the winners), but ignoring such change is dangerous.
Do you, or others, have thoughts about discerning what is a trend to pay attention to vs fads to avoid getting caught up in? Seems like the difference is important. Example: AI is probably a real change…but that doesn’t mean I’m just going to jump into everything AI.
Question 2: Who is your favorite investor, and why?
Peter Lynch, for his endless fluid style, and combination of winning strategies: growth, value, special situations, and using strong trading techniques to add value in a structured way. All backed up by endless business information and study to give an edge in multiple arenas. To be a successful investor (as opposed to being a successful speculator like Soros) you need to understand the businesses you are investing in, and the forces affecting them in their universe.
Question 3: Least favorite, and why?
Harvard Foundation. Does not feel like a coherent strategy as presented.
Question 4: Come up with an AI prompt based on any of the investors that you have
read about in the book.
This is based on Ralph Wanger's observation that in a transforming industry the big money is made outside the core business.
Prompt 1:
Give 5 industries that are currently undergoing rapid change, explain what the change is, with quantitative evidence for the change, and possible outcomes.
Prompt 2:
Take one of the outputs and ask: Make a list of 10 sectors or companies that are likely to benefit from X, except for the companies that have developed it. For example:
GLP-1 drugs are rapidly expanding obesity treatment, which will have knock-on effects for insurers/employers, primary care, and drug pricing. Make a list of 10 sectors or companies who are likely to benefit from this change apart from the Pharma companies who are developing and selling them.
Having a very fluid style, or a very broad range of investing patterns that one looks at can be a strength or a challenge. Very few of us are naturally that 'broad' and forcing it can lead to investing outside of our circle of competence (without realizing it).
1. Jim Rogers: Secular rather than cyclical - focuses on unrecognized or undiscovered concepts or changes, international focus rather than domestic, top-down v bottom-up, buys into whole industries as opposed to picking a singular issue, uses both short and long positions, focus on balance sheer rather than income statement,.
2. Michael Steinhardt: a focus on directional move and market direction, looks at market rather than company, a strategic trader rather than a long-term investor, holds large positions, uses leverage, a consensus v a variant perception, uses a variety of investment styles, primarily short-term but does hold some long positions.
3. Phillip Carret: long-term horizon, small caps, contrarian, good balance sheet, no term debt, 2:1 current ratio, favorable regulatory environment, fundamental research, owner management, never holds less than 10 different securities in 5 types of businesses, re-evaluated every 6 months, 1/2 kept in income producing securities, yield is considered important, quick to take losses, reluctant to take profits, never more than 25% in security lacking details information, avoid inside information, seek facts not advice, ignores mechanical formulas for valuing stocks, when stocks hi, money rates rising, business prosperous, at least 1.2 funds in st bonds, borrow money sparingly and only when stocks are low or falling and business depressed, set aside a moderate position of available funds for purchase of long term options on stocks of promising companies whenever available.
4. George Soros : uses leverage, multi-directional international, speculation in commodities, currencies stocks and bonds, start small, don't be omniscient, must define level of risk willing to take, markets change reflexivity a better approach, perceptions change events, which change perceptions
5. Generational wealth - shirtsleeves to shirtsleeves in 3 generations, most younger generations do not educated themselves as to how money can extend to future generations and societal good.
6. George Michaels: high liquidity, buy earning poser at a discount, hi profit, high roe, high return on total assets, earnings power not susceptible to market cycles, successful for identifiable reasons, buys when companies are cheap and as stock goes down, don't hold when stocks are overprices, doesn't invest in themes, no high multiple returns, good lt management, 10 categories of stock, rate managers against category standard
7. John Neff: value buys cheap, sells when expensive, contrarian, needs income dividends, best investments are least understood, simple management, assesses own performance, less return in up markets less decline in down markets, hi concentration, moves fast on adverse moves, good balance sheet, stable cash flow, above average ROE, able management, satisfactory outlook for continued growth, attractive product or service, a strong market, increases size of position if conviction high, sells when - market price willing to sell, selling price is hurdle rate of portfolio
8. Ralph Wagner: good small companies, identify major trends, buy companies that benefit from major trends, tech hardest to forecast, focuses on both positive and negative ideas, takes rich in proportion to statistical probability of success, tests of a good company - growth potential, financial strength, fundamental value, management owners, low debt, adequate working capital, conservative accounting, attractive price, QUIT test, analyst returns different than market. top down, long time horizon, favorable characteristics that last at least 5 years or longer, low turnover, low expense ratios.
9. Harvard: total return income plus capital gains at least 8%, find a strategy that's out of vogue, relationship is important, mangers that can do what you can't, uses 20% indexing , uses derivatives in a passive index fund, private vs public investments, value conscious, trades options, large number of small transactions.
10. Peter Lynch: focuses on companies on the rebound, visits companies, starts with a lot of stocks and winnows selection down, looks for obvious winners based on changes in key areas, lots of positions, frequently trading, looks at insider buying, unit growth more than earnings, avoids hottest stocks in hottest industries, low pe ratio, earns 15-20% on equity, and 10% on revenues, strong franchise.
Q2.
Phillip Carret - Focuses on individual issues using value characteristics.

Curious - how did AI do with 'Pick 10 stocks that Philip Carret might invest in today.'? Did any of them seem like candidates worth pursuing further?
I haven't used AI - I would just ask it to use Carret's criteria to search for potential investment candidates.
What book will be after Adam Smith? Thanks.
