About

Built by an Investor,
for Investors

DeepAlloc is an independent US ETF publication. One person runs it: TaeMin. This page explains who he is, how articles get made, and the data you can trust here.

Who runs DeepAlloc

DeepAlloc is founded and edited by TaeMin, an individual investor based in Seoul, South Korea. He has been investing in US-listed ETFs for years and started DeepAlloc to write the kind of explainer he wishes he had when he first opened a brokerage account: plain English, real numbers, and zero sales pitch.

TaeMin is not a registered investment advisor, broker, or financial planner. He is a retail investor who reads fund prospectuses for fun and believes most beginners can make excellent portfolio decisions once the jargon is stripped away.

Why write from Seoul about US ETFs? Because non-US investors face a different set of questions — taxes, international diversification, currency exposure, brokerage access — and those questions force a clearer understanding of how US ETFs actually work. That outside perspective shows up in every article.

How articles get made

Transparency first: DeepAlloc articles are drafted with the help of AI research tools, then reviewed, edited, and fact-checked by TaeMin before publishing. Here's the exact process:

  1. Research. Every article starts from fund prospectuses, provider pages (Vanguard, iShares, Schwab, Invesco), SEC filings, and long-running academic references on index investing.
  2. Drafting. AI research assistants are used to organize the material into a beginner-friendly structure. Nothing is published as raw AI output.
  3. Human edit. TaeMin rewrites, reorganizes, and cuts AI phrasing. Every claim about performance, fees, or portfolio behavior is reviewed against primary sources.
  4. Data verification. Expense ratios, dividend yields, and historical returns are checked against the fund provider's official pages. Data points are dated "as of late 2025" or similar so readers know how fresh the numbers are.
  5. Updates. When a fee changes, an index methodology changes, or a referenced number goes stale, the article gets updated. Substantial updates get a updated date in the article metadata.

What we publish

  • Beginner guides — foundational concepts: what an ETF is, how to buy one, what expense ratios actually cost you.
  • ETF comparisons — side-by-side analyses (VOO vs VTI, SCHD vs JEPI, etc.) built on the fund facts, not opinion.
  • Portfolio strategies — three-fund portfolios, core-satellite, bucket strategies, rebalancing.
  • Market insights — historical returns, inflation, corrections, sector rotation — framed for long-term investors, not traders.

There is also a free Portfolio Analyzer that lets you enter tickers and allocations to visualize fees, category mix, and estimated income. Everything runs in your browser session and nothing is stored on our servers.

Editorial principles

  • Clarity over complexity. If a concept needs jargon, we define it the first time and translate percentages into dollar amounts.
  • Data over opinions. Claims are backed by real numbers from fund prospectuses and long-run index data.
  • No conflicts of interest. DeepAlloc does not sell financial products, take affiliate commissions from brokers, or accept paid placements in articles.
  • Free access. Every article and the Portfolio Analyzer are free to use. The site is supported by display advertising.
