I've been looking for services that publish quantitative/rules-based stock model portfolios. Here's what I've found so far:

1. Seeking Alpha PRO Quant Portfolio - 30 stocks, built off their Quant Ratings. This is the name most people run into first. Not cheap though.
2. Stockopedia NAPS - 20-stock rules-based portfolio using StockRanks. Been around a long time, and the track record is public.
3. Stock Doctor Quant Portfolios - a handful of systematic portfolios from quantitative screening/ranking.
4. Phoenix Stock Model - quant portfolios from the S&P 500.
5. Portfolio123 - it's a platform for building and backtesting your own strategies, not a published portfolio you just follow.
6. Persistfolio - S&P 500 quant research with 5/10/20/30-stock model portfolios tracked against the S&P 500.

Found a free tool where you can enter any S&P 500 ticker and compare its historical performance with the S&P 500 across 5, 10 and 15 years. No signup needed. Just in case if anyone finds it useful.

Example:

MSFT performance

Compared with the S&P 500:

5 years: about 4 percentage points/year lower

10 years: about 10 pp/year higher

15 years: about 9 pp/year higher

2022: MSFT fell about 25% the same as the S&P 500. In 2021 MSFT gained 46% vs 28% for the S&P.

I spent the last week building something I thought would become my best customer acquisition tool.

The idea was simple: use AI to scan public conversations and find people expressing problems that my products solves.

The pipeline worked surprisingly well - AI did a good job deciding which posts were genuine opportunities; after reviewing the results manually, I agreed with almost every AI decision; The software itself wasn't the problem.

The problem was finding enough conversations. After testing different sources, I found:

1. Hacker News produced almost no relevant signal for my use case.
2. Stack Exchange had very little commercial intent.
3. Reddit was by far the best source but its API limits and restrictions made the approach impractical for continuous scanning.

Without reliable access to places where people openly discuss their problems the lead generator has nowhere to look.

In the end, I cancelled the project. It was disappointing. Now I'm back to focusing on content, SEO, and search-based marketing for my products instead.

I ran a math simulation experiment comparing a structured, diversified investor with a more reactive individual-stock investor.

Both started with the same money, made the same contributions, and experienced the same underlying market paths. The difference was how they managed their portfolios.

The structured investor followed a target allocation and directed new contributions toward underweight areas. The reactive investor tended to follow recent performance and trade more frequently (hance spending more time managing their portfolios).

I ran 2,000 simulations over 30 years, using a simulated market with hundreds of companies, including weak companies, rare long-term winners, and permanent losses.

The results were:

• Structured investor finished ahead: ~52%
• Individual-stock investor finished ahead: ~48%
• In ~9% of simulations, the individual-stock investor ended with more than 2× the structured investor's wealth
• In ~1.5% of simulations, the individual-stock investor ended with less than half the structured investor's wealth

So at least in this model, structure didn't guarantee a better return. Individual-stock investing produced a wider range of outcomes - sometimes dramatically better, sometimes dramatically worse.

My takeaway was that the value of structure may be less about maximizing returns and more about having a repeatable process with fewer investment decisions along the way.

I made a short video walking through the simulation and results if anyone is interested. Happy to share it.

I make enough money from my main job. Bills get paid, investments get funded, life is good.

A while ago I built a small SaaS tool to solve a problem I kept running into at work. I wasn't trying to start a business. I just wanted something that worked better than my spreadsheet.

Eventually I put it online and started charging for it.

The funny thing is that the money barely matters.

When someone signs up for $4.99, I get way more excited than when my paycheck hits my bank account.

Every new customer is proof that a stranger found something I built useful enough to pay for.

My main job pays significantly more, but those little SaaS notifications bring a disproportionate amount of joy.

Life is funny that way.

Serious question.

​

I often see portfolio posts that look something like:

​

ASTS 38%

MU 25%

TSM 9%

AAPL 4%

META 4%

​

and the OP asks: "Rate my portfolio" or "Should I rebalance?" What exactly do you mean by "rebalance" in this context?

If someone has a portfolio of ETFs with a target allocation (e.g. 60% US, 20% International, 20% Bonds), rebalancing makes sense to me because there is a defined target. But with individual stock portfolios, I'm genuinely confused. Rebalance to what? A maximum position size? Equal weighting? Lower risk? More diversification? Something else?

​

When you ask Reddit whether you should rebalance, do you already have a target portfolio in mind and you're asking how to get there? Or are you asking Reddit to help you decide what the target should be?

​

The same goes for posts titled "Rate my portfolio."

What exactly are people asking to be rated?

​

If I see:

​

ASTS 38%

MU 25%

TSM 9%

AAPL 4%

META 4%

​

I can see the holdings, but I don't know your goals, time horizon, risk tolerance, or what you're actually trying to achieve. Without that information, what does a "10/10 portfolio" even mean?

Is a highly concentrated portfolio automatically bad? Or is it good if it perfectly reflects your convictions?

​

I'm genuinely curious because I see these posts every day and I'm never quite sure what kind of feedback the OP is actually looking for when they ask people to rate it or tell them whether it needs rebalancing.

Been at this for a while now and my requirements haven't changed much - I just want to know what my allocation actually is, whether it's drifted, and where to put new cash. That's it.

Here's where I've landed on the options:

Passiv - still like the concept but the brokerage connection requirement is a dealbreaker for me. I don't love giving read access to my accounts.

Sharesight - great if you care about performance reporting and tax. I don't really need that. Feels like paying for a car when I need a bicycle.

Wealthica - solid net worth dashboard but allocation and drift isn't really its focus. Different tool for a different job.

Spreadsheets - still use one as a backup but maintaining it is its own part time job.

Alignfolio - came back to this one after not looking at it for a while. It's changed a lot. Does allocation, drift tracking, and tells you where new contributions should go to close the gap fastest. CSV upload (love it!) so no brokerage connection needed. Prices update automatically after initial set up so it's not a maintenance burden either.

The one thing I'm still missing is a proper household view - seeing each account individually but also rolled up into one combined allocation. I have a few accounts and the overall picture is what actually matters when making rebalancing decisions.

Anyone solved this without going full portfolio management software?

Has anyone here had real success advertising a B2B product on LinkedIn?

I’m curious about actual experiences.

Things I’d love to hear:

What kind of budget did you spend monthly?

What were your CPC / lead costs like?

Did the leads actually convert into paying customers?

Was the ROI worth it compared to Google Ads, Reddit, Facebook, etc.?

I keep hearing LinkedIn ads are extremely expensive, but maybe they work well for certain niches or high-ticket products.

Would appreciate any honest numbers or experiences good or bad.

Not sure if this is obvious to everyone but it wasn't to me so here it goes.

I have 4 accounts and I used to stress every time I had cash to invest. Should I buy more of what I have, is now a bad time, what if I pick wrong. Every contribution became this whole thing and lots of anxiety.

Then I realized I should have some kind of a plan and I just set target allocations for everything and decided that's the plan. I also carved out a small slice like 10% for random stuff I want to try, my sandbox. Keeps me from convincing myself some new position is actually a core holding when it's really just me being impulsive.

Now when money comes in (accumulated from dividents for example) I just check what's drifted below target and buy that. Don't care where the market is. Simple.

The other thing was ditching the elaborate tracking system. There are tools for this and I personaly like Alignfolio but anything that just shows you drift hystory and where to add cash is enough. It must be something simple.

Investing feels way calmer now. Posting in case it's useful to someone.

Curious how many people here still track their ETF allocation in spreadsheets?

At first mine worked fine… but eventually it became:

• multiple accounts
• overlapping ETFs
• contribution tracking
• rebalancing math
• allocation drift

I realized I understood my holdings, but not my actual allocation anymore.

I’ve been building a simple privacy-first portfolio tracker around this idea (no broker syncing, no trading).

I’m looking for a small group of DIY ETF investors especially spreadsheet users to test the Pro version free for a few months and help shape the platform.

If anyone’s interested, feel free to DM me

Been trying to find a simple way to track my portfolio + rebalance without turning it into a whole project. So far I’ve tried a few things:

Passiv - cool idea with the one-click rebalance. But I don’t love connecting accounts and honestly feels like more than I need.

Sharesight - super detailed but for me it’s way overkill since I don’t check performance that often.

Wealthica - nice seeing everything in one place but it feels more like a full financial dashboard than something focused on allocation.

Alignfolio - probably the closest to what I want. Very simple, just shows allocation + drift but also feels kinda too basic.

Spreadsheets - they work until they dont, hate those.

I feel like everything falls into one of these:
too automated
too complex
or too manual

I just want something that shows what’s off in my portfolio
without me having to constantly update it myself without paying too much.

Anyone using something that actually keeps it simple?

Quick question - curious how people actually do this.

Most advice says to keep a target allocation and rebalance when things drift. Easy enough.

But if your portfolio is spread across multiple accounts, it’s not just “sell X, buy Y”… it’s also where you do it.

Do you just rebalance wherever it’s easiest

try to be intentional about which account you use

or not really worry about it at all

I feel like this part gets ignored. How are you actually handling it?
