Jason has over 30 years of industry experience across Wall Street, Fintech, university-level teaching, and financial journalism.

20 Years in Fintech

Before joining TheStreet, Jason spent nearly 20 years in FinTech, developing dynamically generated AI investment analyses. His work was available at Schwab, TD Ameritrade, Fidelity, ETrade, and nearly every major online broker in the US and Canada. However, his real passion arose when he was asked to write a weekly educational investing newsletter for his coworkers. Topics included why vampires are so rich and what car racing can teach you about investing. These have been republished in Filthy Rich Animal. Learning about investing should be fun!

Jason created the Fear & Greed Index for CNN Business. Although he jokes that it’s his claim to no fame (it’s famous, he’s not), the model for understanding investor behavior has become incredibly popular and is used by everyone from hedge funds to individual investors.

Lecturing at the University Level

Teaching his coworkers led to a role at CU Boulder, where Jason taught classes in Investments and Corporate Finance. He’s no longer teaching full-semester classes but continues to lecture on technical analysis and other investing topics.

10 Years of Wall Street Trading Experience

Jason spent a decade working on Wall Street as a trader and market maker, where he learned all about market microstructure and investor psychology. During his first five years on the Street, he traded mostly closed-end funds and utility stocks. Later, as a market maker, he managed large caps like ExxonMobil, Texas Instruments, Disney, American Express, and Wells Fargo.

When Not Thinking About Markets

Jason’s other passion is cars. He earned the distinction of being the slowest SCCA road racing champion in recent history when he won his region’s Spec Miata class despite having never led a race. Jason knows more about old sports cars than anybody has any right to and is always energized by a drive in his classic Porsche 911.
