🙏 200 issues feels like a lot. Thanks for being a subscriber and sticking with me! To borrow from my first ever issue, “I know it’s a big deal to be welcomed into your inbox, and I want to sincerely thank you for that opportunity. My goal is to deliver interesting links, musings, and other content for your consuming pleasure on a regular basis.”
🎰 Investing and speculating in the public markets. Have you heard the recent stories of Reddit’s wallstreetbets community moving markets? Both GameStop and Palantir short squeezes are attributed to this group. In the past couple weeks, I’ve also heard a handful of stories from ordinary non-finance people about their day trading. Schwab announced in a recent earnings report that the number of households placing trades on their platform was up more than 50% in Q4 and they set multiple records for daily trade volume. Oh, and there’s still a frenzy of trading around SPACs. All this to say that it’s an exciting time in the markets, which is exactly when we should remind ourselves to be careful out there! It’s always better to know whether we’re investing or speculating.
