Been investing for about six years. Work in tech. One thing I've gotten better at over time is distinguishing companies that are 'growing fast' from those with 'durable competitive advantages'. Confusing these cost me real money early on, and I know I'm not the only one.

The core question: If a well-funded competitor built the same product tomorrow with zero users, would customers switch? If yes, that's momentum, not a moat.

Four moat types I focus on in tech:

1. Network effects -> Product value increases with each user. Look at: engagement per user rising alongside growth, take rate stability, and whether value accrues to the *network* or just the *product*.
2. Switching costs -> Painful for customers to leave. Look at: NRR above 120%, 6+ month implementation timelines, deep workflow integration.
3. Scale economics -> Size creates unfair cost advantages. Look at: gross margin expansion at scale, capex as % of revenue declining over time.
4. Data advantages -> More usage makes the product better. Look at: retention curves improving over time, accuracy gains correlated with volume.

How I use this? If I can identify at least one with supporting metrics, I'm interested. If I can't identify any, I treat it as a trade, not a hold. No matter how exciting the growth story sounds.

The biggest trap I fell into early on: assuming 'good product + fast growth' equals a MOAT. Products can be replicated. Growth can be bought with marketing spend. What matters is whether something *structural* compounds over time. Once I internalized that, my whole approach changed.

• What do others use as their primary signal?
• Do you weight one moat type more heavily?

TLDR: Before you evaluate any stock, understand the sector it's in. Different sectors have different economics, different "normal" metrics, and different macro sensitivities. Comparing across sectors without accounting for this is how you end up with conclusions that sound right on paper and lose money in practice.

I've been picking individual US stocks for about 7 years. This is going to sound obvious to some of you, but I'll post it anyway because I wish someone had spelled it out for me earlier: comparing valuation metrics across sectors without context is a complete waste of time.

The mistake I kept making

My first couple years, I'd run a screener, sort by P/E, and go looking for "cheap" stocks. Found a bank at 10x earnings and a SaaS company at 35x? Obviously the bank is the deal, right?

Except no. A bank at 10x might be expensive if you're heading into a credit cycle and their loan book is full of garbage. A SaaS company at 35x might be cheap if it's compounding revenue at 40% with 80% gross margins and customers who can't leave without rebuilding their entire workflow. I was comparing completely different types of businesses using the same ruler and getting confused when my picks didn't work out. Took me longer than I'd like to admit to realize the ruler was the problem.

What actually helped me?

I started asking one question before looking at any numbers: what sector is this company in, and what are the specific questions that matter in that sector?

• Tech: Is this a platform or a feature? What are switching costs? How do margins move as the business scales?
• Healthcare: How exposed is revenue to patent expirations? What's in the regulatory pipeline? How binary are the upcoming catalysts?
• Financials: Where's net interest margin headed? What does the loan book look like if unemployment rises 2%? Is management buying back stock, growing, or hoarding cash?

Once I started evaluating companies against sector-specific benchmarks instead of the market as a whole, my research got dramatically sharper. "cheap" started meaning something because I was measuring against the right baseline.

Why this compounds?

Here's the other thing. After you've deeply researched 5 or 6 companies in the same sector, the 7th takes half the time. You already get the industry dynamics. You know what the standard metrics are. You've developed an ear for what management BS sounds like in that specific context vs. what genuine confidence sounds like.

Most retail investors (younger me included) bounce between sectors randomly. Research a bank, then a pharma company, then a semiconductor stock, then a retailer. Never build any cumulative knowledge in any one area. That's a self-inflicted handicap.

Where I've landed

If you're earlier in this process, I'd say start with whatever sector is closest to your day job. You already have contextual knowledge there that other investors don't. You just need to learn to point it at stock analysis instead of keeping it compartmentalized.

Curious if others have had the same experience. Did specializing in 1-2 sectors improve your results vs. jumping around?

TL;DR: If you buy individual stocks, it's worth asking whether you're spreading your research too thin. Going deeper on fewer ideas, even just one a month, might do more for your returns and your nerves than another watchlist ever will.

I've been investing in individual stocks for about 8 years, and I want to share something that took me embarrassingly long to figure out.

More research isn't the same as better research

Early on I assumed being a good investor meant taking in as much information as possible. I followed 30-plus tickers. I watched every earnings call. I read all the Reddit threads. I had a watchlist a mile long.

My returns were mediocre. And eventually I understood why.

When you split your attention across 20 or 30 names, you end up with opinions instead of actual convictions. An opinion sounds like "this seems like a good company." A conviction sounds like "I know why margins should expand over the next few years, I know how competitors will probably react, and I know exactly what would tell me I'm wrong." Those are not the same thing, and the market can tell the difference even when you can't.

Why it matters when things go sideways

Shallow knowledge gets punished. A stock drops 15 or 20% on nothing in particular (macro jitters, one soft quarter, sector rotation) and now you have a decision to make. If you actually know the business, you can look at it and figure out whether anything real has broken. If you don't, all you feel is fear, and fear is what makes people sell at the bottom.

I paid attention to my own behavior for about a year and a half. Every position where I'd put in real work, say 10 hours or more, I held through the drawdown and usually came out fine. The ones I'd bought on a thin thesis (a Reddit DD, a buddy's tip, something that popped up on a screener) I bailed on at the first dip, almost always at a loss.

So I changed how I work. Now I let myself research one new idea a month. That's the whole rule. One company, gone through properly: the business model, the unit economics, where it sits competitively, how management spends money, and roughly what it's worth.

Two years in, I own about 18 companies I genuinely understand. The portfolio is more concentrated than it used to be, but I'm far more sure of what I own, and I behave completely differently when the market gets ugly.

This isn't some original theory: Plenty of the best institutional investors run concentrated books.

Anyway, curious how this lands for other people. Do you make better calls on the stuff you've actually dug into versus the stuff you bought on a hunch?

Folks, how do you find good US stocks to invest? Been burned myself and lost 1Cr. Still want to invest but need a reliable source to choose which stock?

How do folks do it?

NRIs, how do you currently discover US stocks for long-term investing? I can’t find a reliable source (dnt wanna listen to family members) and I find wealth managers too expensive.
