The year-by-year story

Prologue
Algo born at Hack Reactor, 2013
I built the first version of the algorithm in September 2013 at a coding bootcamp called Hack Reactor — well documented enough to land in a 2013 Wired article. After three years of refinement, backtesting, and being a bad salesman to investors, I ended up trading my own money rather than raising capital.
2016
Started with $139k, made $555,518
After a lot of backtesting, forward-testing, and coding improvements into the algo, I gained the confidence to start betting big on it in 2016. Starting from $139,009.51, I made $555,518.12 that year before commissions, fees, and taxes.
2017
Made $2,518,578 across personal + LLC
I thought my 2016 results were pretty cool so I bet really big on the algo in 2017 and made $1,735,394.83 + $783,182.92 = $2,518,577.75. Mid-year I switched to trading under my LLC on CPA advice.
2018
Only losing year — down $649,000
This was my only losing year. I was reeling from a serious relationship ending and made a lot of emotional trades that went against what my software told me to do.
2019
Recovered $577,000
I tepidly made $577k this year. At this point I was still in worse shape financially than 2017 because I technically lost money during the following two-year period (2018–2019) while still having to pay my living expenses. This was really quite disheartening and I was pinching pennies while trying to make ends meet.
2020
Retail floods in. Made $2.2 million
COVID-19 brought a ton of retail traders into the markets. Citadel Securities (just one market maker out of hundreds) made record profits of $6.7 billion this year. When the market makers make money, I make money — my strategy is to piggyback on what they're doing. After a 2-year slog, I finally had renewed hope. Made $2.2 million.
2021
Made $2.44 million + shorted treasuries
Made $2.44 million. Withdrew $4.5M because my algo detected something strange in the treasuries market — I spent the year telling friends and family to short them [12/7/2021 screenshot]. Bought a Walmart Plaza nearby for $7M as an inflation hedge, plus $1M into a QOZ fund.
2022
~$3 million in real-estate gains, lifetime total: $10M
With so much of my money tied up in real estate, I spent this year focused on developing BigShort and managing my plaza. I sold one building in December for $4.6 million and plan to sell the other for $5.4 million — a greater than 100% return in 1 year of being a landlord.
2023
Stepped back from active trading
Spent this year slacking off, working on BigShort with Andrew, and spending time with my new girlfriend (who I just recently broke up with prior to writing this 😂). I'm almost 40 — I sacrificed a lot to become rich and I don't want to be the richest guy in the graveyard.
2024 / 2025
Public track record continues
Track record updates are now published on the BigShort blog as the years close out. Read the 2024 / 2025 update.
END NOTE EPILOGUE

In 2009, I was admitted to the 8th best law school in the country, the University of Virginia School of Law. It was the hardest decision of my life to choose not to attend, and even more so being the son of Korean immigrants. As a 25 year old riddled with self-doubt and financial insecurity, I had an option to pursue a very safe, well-paid and prestigious career in law. It's all that I had ever wanted, having grown up without anyone believing I could do anything, and finally getting that validation that I was good enough to get put into the game. And yet I was so used to people not believing in me that I couldn't help but feel uncomfortable at the thought of not being on the outside anymore. I didn't know how to kiss ass like Tom Wambsgans or be a part of polite society — I only knew how to believe in myself.

I'm telling you this story because I know that the other story I'm telling you is even more unbelievable: the story of a kid with no money, no job, and no connections somehow cracking the code of the markets and creating trading software which no one believed in enough to invest in despite it outperforming every Wall Street hedge fund and generating millions of dollars in profits. I'm aware that from where you're standing this story makes absolutely no sense and I can assure you that it doesn't make sense to me either.

We live in a world where the daughter of an Enron executive need only don a black turtleneck and talk in a fake deep voice in order to be worth billions. My working theory is that humans are bad at judging value, and they rely on proxies of value such as social proof, of which I had none. I still have none, which is why despite literally posting my brokerage statements and tax returns on this webpage, naysayers and skeptics will surely continue to doubt my accomplishments. I'm the antithesis of Elizabeth Holmes: unrecognized, with no pedigree, no swagger, and neither the desire nor the ability to manipulate people into believing in me. So that's the story of how I got here.
