- 3

— Valuation view
20:06 “With Duolingo's 75 PE ratio, PE ratios should be given in context of growth and predictability. Duolingo grew their earnings per share by 73% year-over-year last quarter.”
- 5
— Disclosed buy
14:52 “As of today, the company that I bought $5,000 more of, I just bought it this morning, is Duolingo. This is one of the few companies in the red in my portfolio. It's currently, with the $5,000 buy today, a $20,000 position with $15,000 in the red.”
He was describing purchases he made during a market sell-off.
- 6
— Risk acknowledged
10:09 “Duolingo is down a staggering 69.3% over the trailing one year. Investors believe that there's going to be lots of ways to learn languages, lots of AI enabled tools, and Duolingo doesn't have enough to distinguish itself.”

— Not buying more
31:38 “So, as of right now, my plan is that I'm not buying more into Duolingo, I'm not going to continue to throw money into this position, but I will hold it because I believe that there is huge potential upside here in the future.”
This followed a 20% drop in Duolingo's stock. He said it was about a 1% position in his portfolio.
- 8
— Disclosed buy
9:51 “I bought $5,000 worth of this one February 10th at a share price of 121.”
In an April 2026 review of recent purchases, he recalled an earlier Duolingo buy and said the stock was now at 103, below that buying price.
- 9
— Hold, bullish
8:43 “We have Duolingo, which I haven't sold a single share. I'm currently down 55% or $22,000, and Duolingo has held at around $100 per share. I believe it's finally found a base.”
- 10
— Risk acknowledged
29:23 “And I expect that over this next year things might be slow with Duolingo. I have no problem with that because I believe that there is opportunity here.”
After earnings, he discussed slowing growth and noted that revenue and bookings were projected to grow slower than investors expected, while daily active users still grew 21%.
- 11
— Hold, bullish
20:56 “I don't share that bear thesis. I don't think that's going to happen with Duolingo. I think that they're going to continue growing in their users and engagement and learning because that's all they focus on.”
He was responding to the concern that AI tools like ChatGPT, Claude or Gemini will take over language learning from Duolingo.
- 12
— Conditional
21:22 “And the buy-in target for this one for the additional $10,000 is going to be at $90 per share. So, if Duolingo goes back down to $90 per share, it'll get an additional $10,000.”
Reviewing his holdings and the price levels where he would add more, he noted Duolingo was trading at $146 at the time.

How to read this
Quotes are short excerpts from Joseph Carlson's public YouTube videos, attributed to the speaker and linked to the timestamp. “Close that day” is DUOL's split-adjusted closing price on the day the video was published (New York time); if markets were closed that day, the last close before it. If the stock has split since a quote, the card shows the price it traded at that day and, beneath it, the split-adjusted close the % change uses. “Since” compares that close with the latest close on 2026-10-28. It is a price observation, not the creator's realized return, and not investment advice. How the price change is calculated. Next to it we show SPY, the ETF tracking the S&P 500, over the same two dates — so a move can be read against the market rather than on its own: why we compare with SPY. Each quote also carries a label — Named as a pick, Risk acknowledged, Reducing — describing what kind of statement it was: see what the labels mean.
