I screen 887 stocks every week using Peter Lynch’s methodology. Here’s what came back most interesting this week.
Author uses Peter Lynch's framework and Soros reflexivity to find undervalued fast growers like META and BSX trading below fair value.
- Identified as 'Fast Growers' with low PEG ratios trading below calculated fair value.
- Exhibiting a 'Negative Loop (Panic)' Soros signal, indicating irrational market bearishness creating a buying opportunity.
I've spent the last few months building a systematic stock screener that applies Peter Lynch's framework from One Up on Wall Street across the S&P 500, FTSE 100, Nikkei 225 and major Emerging Markets. Every stock gets assigned a Lynch category and a fair value calculated using category appropriate multiples. I also layer in a Soros reflexivity score to flag where sentiment appears to be driving price away from fundamentals.
What's interesting about this week's screen is that almost everything flagging as undervalued is also showing a Negative Loop (Panic) Soros signal simultaneously. That combination, Lynch says cheap while Soros says the market is irrationally bearish on it, is historically where the most interesting opportunities sit.
This week's standouts:
BSX (Boston Scientific) — Fast Grower, PEG 0.59, 24% below fair value
COR (Cencora) — Fast Grower, PEG 0.64, 22% below fair value
META — Fast Grower, PEG 0.91, 14% below fair value
ROP (Roper Technologies) — Fast Grower, PEG 1.33, 20% below fair value
NEC Corporation (Japan) — Fast Grower, PEG 0.34, trading at a significant discount with the market completely ignoring it
The Japan angle is worth a conversation. There are genuinely cheap fast growers on the Nikkei that Western investors almost never look at. NEC, Nintendo, KDDI, all showing strong earnings growth relative to what you're paying.
Curious what others think about the methodology and whether anyone else is finding the same names. Pushback welcome.
These AI responses are so obvious
I guess this is approximately what happened when people started using typewriters for writing letters 😀
Cool AI response
You're right to push back. I didn't actually create a response at all. Here's what happened...
🤬

Bs. BSX PEG = 2.00 not 0.59 if you include temporary/special items.
Are you a bot?
It ironically makes you sound disingenuous.

META for sure. It drops on any news at all, or even rumour. The numbers don't lie.
Invest a company with scum CEO? nah
Bro stop with the AI responses
BSX is notably a big Trump trade. He picked up about a million dollars worth last month. Been eyeballing it.
Bought a small stake past month. Great company with a great future. They deliver implants for cardiac things, but also disposable grepping gear for endoscopy / colonoscopy procedures. 2 procedures that in itself will increase a lot also in a much younger population. I myself got my own colonoscopy at 25 past year and will get an endoscopy this year as well.
Good question. It’s built from a combination of factors including where the stock sits in its 52 week range, the gap between current price and analyst consensus target, analyst recommendation sentiment and P/E premium or discount to the market. The idea is to identify whether sentiment is driving a self reinforcing loop away from fundamentals in either direction. It won’t tell you anything a price chart can’t suggest but combined with the Lynch PEG it flags whether something is cheap because it’s genuinely cheap or cheap because the market is irrationally panicking on it.
Dude we are so cooked.
And you screened over 800 companies using ai, how? What database is it connected to? Please don't tell me you just ran a prompt and made it find the data on its own using Yahoo finance and such
I recognize some of these words
Why is meta a value stock?
We all do, that’s what makes it your own voice. Without practice and praxis we lose our voice.
Don’t rent yourself from someone else.
Are you incapable of typing out even a three sentence response on your own? Good lord
this is pretty cool. but it's still just a more advanced stock screener. you gotta touch the stuff to do any peter lynch investing.
i'm telling you nintendo has issues. the games suck. they're overpriced. the neckbeards are on steam and the kids are on roblox...
meta also stinks. facebook and social media business is amazing but zuck is the weakest in the AI gold-rush... the naked emperor who spent billions on wii characters in vr...
also reflexivity has more to do with self reinforcing trends. so sentiment is like a one dimensional gauge of a multi dimensional beast.
