This deck walks you through the building blocks of long-term, low-cost investing. You'll start with the basics of index funds and ETFs, then move into how to combine them into a simple portfolio, why bonds play a role, and how to keep your allocation on track over time. Along the way, you'll touch on the practical stuff that often trips people up, like tax-efficient fund placement, wash sale rules, and how to think about expense ratios in real dollar terms.
It's a great fit if you're new to investing and want a structured way to learn the core concepts without getting lost in jargon, or if you've been investing on autopilot and want to understand the "why" behind your choices. The questions on risk tolerance, sequence-of-returns risk, and the difference between dollar-weighted and time-weighted returns are especially useful for anyone thinking about retirement planning or how their own behavior affects returns.
Because many of these ideas build on each other, try reviewing the cards in order the first time through, then let spaced repetition do its job on follow-up sessions. A useful habit while you study is to pause after each card and ask yourself how the concept would apply to your own portfolio — it turns abstract knowledge into something you'll actually remember when it matters.
