Why I am bullish on DoorDash

[Full disclosure: I own DoorDash stocks. This is NOT investment advice. Do your own due diligence.]

I have been bullish on DoorDash since early 2021. Finally, I got some time to share my thoughts here on the blog. Because it is a short blog piece, I only have space to highlight a few key topics.

Bullish views

In many Asian countries, food delivery apps have fundamentally changed how people eat. These apps are convenient and affordable. In some cities, food delivery apps have achieved “cost parity,” meaning paying for food deliveries costs about the same as buying ingredients and cooking them at home! Bullish investors bet food delivery’s success in Asia can be replicated in the U.S.

Takeaways from “The Alchemy of Finance” by George Soros

I might have already read the book long ago, probably its Chinese translation copy when I was in college or in high school. I cannot exactly recall. Over the weekend, I finished reading the English copy of The Alchemy of Finance for the first time. To be frank, I was expecting more than what I ended up getting. But that does not stop me from saying that this book remains a unique investing book. If you have not read it, you should consider giving it a try.

I am not going to repeat what the book preaches but to share a few thoughts I had when reading through it.

“Reactive” can be a good thing

[Full disclosure: I own the KWEB ETF.  This is NOT investment advice!  Do your own due diligence.]

“Reactive” is a word that sounds passive and negative. People do not like this word. In investing, I like to argue however, “reactive” can be a good thing.

To proactively predict the financial market is an extraordinarily hard thing to do. Proactively predicting companies’ futures is hard — that is why good stock pickers are rare. Predicting the market is harder — that is why there are extremely few investors who can make it big by just market-timing.

Takeaways from “You Can Be a Stock Market Genius” by Joel Greenblatt

You Can Be a Stock Market Genius has handsomely exceeded my expectations, not because of how short the book is (yes, it is a quick read) but because of how good its messages are. Joel Greenblatt compounded his fund at 50% a year for about ten years before returning all external capital in 1995. Surely, there is something to be learned from Joel’s book. Here we go.

Understand people’s motives

The word “motive” / “motivation” appeared at least 10 times throughout the book, while accounting-oriented fundamental analysis did not make an appearance until the second last chapter. It is not that proper accounting computations are unimportant but that for successful investing, a human understanding of the other humans in the same market is terribly important as well. That, I think, was a key message that Joel was communicating. In analyzing spinoff situations, Joel wrote, “analyzing the actions and motives of insiders … is of particular benefit.”

Takeaways from “The Prince” by Niccolò Machiavelli, translated by Peter Constantine

Disclaimer: given the uniquely notorious reputation surrounding the book and the author, I want to make it clear that, in this article, I am not commenting on the morality of the book nor the author — I have zero intention in writing or implying anything in that regard.

Recently, I got a chance to read The Prince — the remarkable yet controversial book by Niccolò Machiavelli. Many people hold extremely negative views about the book and its author. Others see the book as one of the most influential works for modern political philosophy. I didn’t expect much prior to reading it.

Post the read, to my surprise, I realized the author Machiavelli might possess some of the qualities that are needed for successful investing.

Two Hours of Almost “Free” Money

This is NOT investment advice! Do your own due diligence.

Chinese equities suffered sharp selloffs due to policy-related concerns. KraneShares CSI China Internet ETF (“KWEB”), a popular Chinese ETF, declined by as much as 25% over the three-day period from last Friday to this Tuesday — a massive decline since KWEB has previously already declined by 40% from February to June! By Tuesday night, KWEB was down more than 55% from this year’s peak. See the chart above. What a financial “bloodshed”!

If one were watching the market close enough, he/she could discover an asymmetric opportunity during the Tuesday selloff. In a nutshell, between 11:30am and 1:30pm Tuesday (July 27, 2021), for KWEB, its exchange-listed long-dated call options were selling at a price so low that basically “guaranteed” investors great returns.

SPCE | Virgin Galactic, an unpowered glide for now

Virgin Galactic had a successful test flight on July 11, 2021. See the flight path above. After reaching its peak, VSS Unity came down through an unpowered glide. I believe the exact same has been happening on Virgin Galactic’s stock price (ticker: SPCE), peaking out during the test flight weekend and continuing its unpowered glide downward.


For SPCE, bullish arguments are obvious: large TAM, software business–like EBITDA margin, etc. The company even dedicated a section of its public filings to touting its TAM and potential profit margin levels.

Takeaways from “The Code Breaker: Jennifer Doudna, Gene Editing, and the Future of the Human Race” by Walter Isaacson

I recently read The Code Breaker: Jennifer Doudna, Gene Editing, and the Future of the Human Race by Walter Isaacson, the bestselling author of Steve Jobs. The book started at the story of Jennifer Doudna and expanded onto the potential applications of gene editing and what that technology could potentially mean for the human race. I highly recommend the book.

My key take-aways are as follows:


Curiosity-driven motives lead to unusual discoveries

The word “curiosity” appeared more than 30 times in the book. It reminds me of the principle that I always think about, “If you don’t have passion, you cannot win.”
