The question I get most often, from people who've been meaning to start investing for two years or from friends with a brokerage account they're not sure how to use, is some version of: is this the right fund?
Not: is this fund cheap? Not: does this overlap with what I already own? Just: is this the right one?
That question is usually code for something else. It's code for: I don't fully understand what I'm choosing, and I'm not sure who to ask without feeling like I should already know this. The person who's been investing for 15 years and the person who just opened their first Roth IRA are often scared of exactly the same thing. The vocabulary is different. The underlying uncertainty isn't.
That's the gap this site was built to fill. Not a textbook, not a sales pitch, not a hype channel — just honest explanations from someone who's worked with investors long enough to know which things actually matter and which things just sound like they do.
What ETF BFF Is
ETF BFF is a free ETF education platform. No jargon, no sales pitch, nothing to buy. The whole thing is built on the belief that most people make better investing decisions when they understand what they're actually investing in. And most of the resources out there make that harder, not easier.
The site has three parts:
- The Guides are the reference layer. Step-by-step, built for someone starting from zero. ETF Basics is where to start if you've never bought an ETF. The 3-Fund Portfolio guide is where to go once you want a real strategy. The Expense Ratios guide has the math on why fees matter more than the industry wants you to think. Come back to these. That's what they're for.
- The Tools let you run the numbers on your actual situation. The Fee Calculator shows you what your expense ratio costs over 30 years. The result is usually bigger than people expect, and that's the point. The Portfolio Analyzer maps overlap and concentration across the funds you already own.
- The Expense Report is the weekly newsletter. One concept, explained clearly, in about five minutes. No stock picks, no predictions. Just one thing worth understanding that week.
What This Blog Is
The guides are thorough by design. The newsletter is short by design. This blog is where I actually think out loud.
Not in a journal-entry way. In a "here's a real question investors wrestle with, here's what the data shows, here's what I think, here's where I'm genuinely not sure" way. Posts rotate across five themes: ETF fees and costs, portfolio building, market context, investor psychology, and fund comparisons. The fees and portfolio categories show up more often. That's where most of the avoidable mistakes live, and that's not an accident.
A lot of finance writing hides behind nuance. Everything "depends on your situation." Sometimes it does. But a lot of the time, someone saying that is just avoiding the question. I'd rather give you a position and explain the reasoning, so you can decide if I'm wrong, than hand you ten variables and wish you luck.
Who Writes It
The author holds the CFA® designation and has worked extensively in investment analysis. The same questions come up constantly, just dressed differently depending on how much someone has already read.
Note: The views in this blog are general educational opinions and do not constitute investment advice, personalized recommendations, or the views of any employer or firm. Nothing here is a substitute for advice from a qualified financial professional who knows your full financial picture.
I'm not using my name here. ETF BFF is deliberately not a personality platform. I have a day job, I'm not building a personal brand, and I'd rather the work speak for itself. But I'll write in first person, because finance written in the third person by committees sounds exactly like what it is.
When I say "I've watched investors do this," it's real. Not a scenario invented to make a point feel weightier.
This blog isn't neutral. Neutral is what you get when someone's more worried about being wrong than about being useful. My actual views, stated plainly: most investors own too many funds, pay too much in fees, and check their accounts too often. A three-fund portfolio held for decades beats most strategies. Low-cost index funds beat most active managers over time, by a margin that compounds. Boring works. I'll label opinions as opinions and show the reasoning, so you can push back if you disagree. That's the whole point of doing this in writing.
Where to Start
If you're new to ETFs, start with the guides. This blog assumes you know the basics, and if you don't yet, ETF Basics is a faster read than you'd expect.
If you already know the fundamentals and you're trying to make a specific decision (which fund, what allocation, whether bonds belong in your portfolio right now), this is the right place. Browse by category or start with whatever's most recent.
And if you want one useful thing per week without having to remember to check back, The Expense Report is the best way to do that. Free, no spam, and short enough to actually read.
If you remember three things, make them these:
- Bring actual questions, not hypothetical ones. Real stakes make this more useful.
- Every post has an opinion and the reasoning behind it; the reasoning is the part worth reading, because that's what you can actually push back on
- The guides are the reference layer. Start there, then come back here once you've read them and still aren't sure.
