An investing group for do-it-yourself ETF investors.

Know what you own. Look inside your ETFs.

Every ETF is a portfolio in itself. Your understanding of it determines your conviction in it when you need it most. We take the most widely held U.S. funds apart holding by holding, every week, and show you the numbers underneath the ticker.

The problem

Conviction is a research problem.

One ticker, hundreds of positions.

A broad index fund holds ~500 stocks. Put four funds together and you own several hundred companies, with the same names sitting in three of the funds at once.

The fact sheet stops at the top ten.

An expense ratio, a yield that may be trailing or forward, and ten names. The other few hundred positions, the earnings behind them, and the valuation of the whole book are not on it.

The drawdown is the test.

When a fund is down 20%, ‘it’s diversified’ is not a reason to hold. Earnings still growing, the dividend still covered, a valuation at the bottom of its own range: those are reasons, and you can only use them if you know them.

How we read a fund

Underneath the ticker it's a book of companies. So we read it like one.

Take four of the most widely held U.S. ETFs at 25% each. Portfolio X-Ray lays every position out by weight and by the fund it came from. Then the look-through starts: earnings, margins, free cash flow, dividend coverage, growth, and a forward valuation measured against the fund's own history.

Is this for you

This is for you if

  • You build and hold your portfolio out of ETFs, for growth, for income, or both.
  • You compare two or three funds before you buy one.
  • You already know the fact sheet doesn't hold all the answers.

It isn't, if

  • You want stock picks, CEFs, BDCs, REITs or mutual funds. ETFs only, on purpose.
  • You want corporate or municipal bond coverage. We do Treasuries.
  • You trade on a week-long horizon. The portfolios rebalance a few times a year, and the tactical sleeve trades about monthly.

Questions

What is ETF Portfolio Mechanics?

ETF Portfolio Mechanics is a Seeking Alpha Investing Group built around ETF research: holdings-level, look-through analysis of the most widely held U.S. ETFs, four real-money all-ETF model portfolios for growth and income, two weekly ETF chartbooks (the Macro Market Monitor and the Dividend Monitor), a monthly report of every U.S. ETF launch and closure (ETFTrack), and a member research portal with tools like Portfolio X-Ray and ETF Compare. It is co-led by Jack Bowman and Cain Lee and covers ETFs only: equity, dividend, option-income, alternatives, gold and Treasury funds.

Do I need Seeking Alpha Premium?

No. Membership is separate from Seeking Alpha Premium, and you don't need Premium to join.

Which funds do you cover?

~30 of the most widely held U.S. ETFs every week across the two chartbooks, plus any U.S. ETF a member asks for, two of those a week. Equity, dividend, option-income, alternatives, gold and Treasuries. Not corporate or municipal bond funds, and not stocks, CEFs, BDCs or mutual funds.

How often do the portfolios trade?

A few times a year. The growth portfolio carries a tactical sleeve that trades about once a month. Every trade comes with an alert and the reasoning, and the trade log stays up for members.

Can I ask you to cover a fund?

Yes. Two member-requested tickers a week, up to four when it's a comparison. First-time requesters go first, and members see requested coverage before anyone else.

When does each piece publish?

Portfolio updates on Monday, requested coverage on Tuesday and Thursday, the Macro Market Monitor on Wednesday, the Dividend Monitor on Friday, ETFTrack on the first Wednesday of the month, and a live Q&A monthly.

Be first in.

Look inside your ETFs, every week, with two analysts who hold the same funds.
