What Hacker News says
- I started my investing journey as an uninformed, word-of-mouth hype stock buyer. I bought stocks based on what my lift-club colleagues, barber and finance talking heads on the news were discussing. For years I never made a profit, buying compulsively and selling in panic. Then I was introduced to value investing by reading ‘One Up On Wall Street’ by Peter Lynch. This book taught me to invest in businesses I understand, analyze financial statements and invest for the long term. Since I started following this approach, I’ve made real returns, not looking at stock prices every 30 minutes, and going to bed knowing that my best returns are yet to come. Finding value can be difficult though, so I started building some tools to help automate much of the analysis process. The true foundation of intelligent investing rests on dissecting financial statements to uncover enduring corporate fundamentals. Screening companies for strong fundamentals is much easier when you have access to historical financial statement data (10-20 years), a way to visualize that data, and create reports of your analyses. I put together the tools I’ve been working on over the years in a singe web-app (aimed at PC use), and would like to share it with like-minded investors. The app is intended to be simple, focusing on the core aspects of financial statement and equity analysis. The app offers four core features: 1. Access to historical financial data of American publicly traded companies 2. Metric builder to define custom derived metric formulas 3. Report canvas to collate data visualization and insights for export 4. Virtual portfolio builder to create and track custom portfolios/indices You can test these feature’s through Capote’s free tier. If you have feature requests, notice any bugs, or have other inquires, feel free to reach out ! I hope to build the application based on the needs of the investment community – so all feedback would be greatly appreciated.
- A seasoned investor’s honest reflection: from losing tens of thousands to eventually making over 100,000 — and the one thing I finally did right.
A few years ago, I couldn’t imagine my brokerage account showing six-figure assets. This isn’t a story of sudden wealth. No insider tips or “limit-up secrets.” It’s a story of losses, confusion, learning, and slow redemption.
If you’ve ever doubted yourself after painful losses, maybe my experience will feel familiar.
1. Entering the “casino”
In 2016 I bought my first stock simply because it “had been rising.” A tiny gain quickly turned into losses. Panic → adding positions → cutting losses. I thought I just “lacked skills,” so I learned every indicator: MACD, RSI, candlesticks… The more I learned, the more confused I became. My trading still looked like gambling.
2. Discovering value investing
Right before quitting the market entirely, I stumbled upon “value investing.” That moment changed everything.
I read the classics:
The Intelligent Investor — stocks = businesses
Security Analysis — intrinsic value matters
Buffett’s letters — buy understandable companies with moats
One Up On Wall Street — growth also matters
The Most Important Thing — risk and second-level thinking
These books rewired my thinking: I wasn’t investing; I was betting on noise.
3. Building a real system
I studied macroeconomics, business models, and financial statements. I shifted from watching daily candles to examining revenue, margins, cash flow, competitive advantages. Short-term prices are unpredictable; long-term fundamentals aren’t.
4. The real test: U.S. market volatility
When I applied value principles to U.S. stocks starting in 2019, my portfolio grew — until the real psychological test arrived.
The pandemic crash, rate hikes, inflation spikes, tech sell-offs, rotation from growth to value… volatility in U.S. markets came in waves. Friends told me to “sell before it’s too late.” I was anxious too — but I had done deep research. I knew the businesses I held: their fundamentals hadn’t changed.
So when fear peaked, I added to my positions instead of running. Markets eventually stabilized, and the recovery validated the analysis. My account went from deep red → break-even → steady profit → eventually passing +100k.
This wasn’t luck. It was discipline meeting patience.
5. A decade of learning distilled into a tool
Value investing works — but it requires time: reading filings, analyzing statements, building valuation models. Most people simply can’t spend dozens of hours per company.
After writing thousands of pages of notes, I wondered:
Can I turn my entire investment workflow into a tool?
A tool that:
screens for quality companies
auto-analyzes financial statements
evaluates fundamentals & valuation
removes 90% of repetitive work
I’m a zero-code beginner, but with AI’s help, I spent half a year building it.
The result: https://aistock.tools
It’s not a trading cheat code. It doesn’t predict next week. It simply generates one-click stock analysis reports based on the value-investing methods I’ve refined for nearly a decade.
Enter a ticker → get fundamentals, profitability, growth, valuation, risks — all structured and readable.
I built it for myself first. Now I’m sharing it in case it helps others shortcut years of trial and error.
If this tool becomes even a small accelerator on your investing journey, then the work was worth it.
- Interest rates are decent for cash right now (able to get 4.5% in the states as of Dec).
If you want a relatively hands off approach what everyone has already suggested is your best bet, index funds.
If you like individual stock picking then I recommend in terms of personalities Lyn Alden (twitter, and personal website), Unrivaled Investing (youtube, also has a paid membership), also interviews/Berkshire investor days with Buffet and Munger on youtube. In terms of the classic resources you have "The Intelligent Investor", "One Up on Wall Street", "Security Analysis", "The Little Book that Beats the Market", etc. Please be mindful that this option is a long journey with lots of reading, making mistakes that results in "paying tuition to the market", and not for those who can't control their emotions when it comes to the stock market. However, if like me you find this fun for whatever insane reason then that's where I'd recommend starting FWIW.
- Those companies don’t come often, but you don’t need many winners to be all set.
I saw Google before the rise, Amazon, Apple, Bitcoin and Tesla. I only acted on Tesla after seeing all the other ones before but didn’t put my conviction into action.
It’s not very hard: you read HN daily/weekly and listen to the trends. Pick one that keep coming and interest you and dig deeper, you are not in a hurry as HN is way early in the cycle, the danger is being too early and giving up before it catch up. (Bitcoin)
Pick one big potential winner, calculate the expected value as good as you can Good/Bad scenario, place your bet, let the time do it’s thing.
An example of a bet I didn’t do: Bitcoin was 1$, I knew that if it worked very well it could go to 1M$. Let say you think that the probability of success is 20%: (1M$/1$)*20% = 200 000 to 1. You then place let say 5k$ on bitcoin and forget about it for 10 years.
At the moment, I don't see a trend that catch my attention beside AI and for the moment I think Tesla will be the winner in that trend.
Look up the book: one up on wall street
- I wish I could remember the name of the book, but I remember a few stories. The author was a young broker, and had a truck driver client. The truck driver was pretty adamant about investing in this factory that kept growing every time their route took them out there. It was a tampon factory, and there was institutional bias about dumping millions into women's products. Truck driver ended up retiring early.
Another was Pep Boys, the name is stupid, hard to pitch to an institutional investor, but made tons of money when someone got over their embarrassment.
Aside from biases, He called out La Quinta, you experience doesn't have to be super deep. The guy recognized it was clean, inexpensive, not the Ritz but a solid deal for what you got.
The last strategy that I thought was sorta odd (but makes sense) is companies that own big chunks of other companies. Their example was AT&T being cheap, but owning big chunks of cell phone companies. We sorta saw the same thing play out with Yahoo and Ali-baba.
Peter Lynch! One up on Wall Street! Probably super dated now, but was a pretty interesting perspective on trying to see things other people didn't see.
- One Up On Wall Street, Peter Lynch
