Podcast appearances and mentions of John Yang

In this episode, Ben Felix and Braden Warwick unpack the surprisingly complex world of expected return modeling and why it matters so much for retirement projections, portfolio construction, and financial advice. They explain how PWL Capital currently estimates expected returns across asset classes, why traditional Monte Carlo methods relying on Gaussian distributions may miss important market behaviors, and how new research could improve the realism of long-term financial planning simulations. The conversation also explores a fascinating collaboration between PWL and Columbia Engineering student John Yang, who worked with Professor Michael Robbins on a project to build more realistic synthetic return data for financial planning. John explains how his team used empirical distributions, t-copulas, and Extreme Value Theory to better capture market crashes, fat tails, and asset co-movements during periods of stress. Ben and Braden then analyze how these improved simulation methods affect financial planning outcomes, sustainable spending estimates, and projections for long-term wealth accumulation.   Key Points From This Episode: (0:00:00) Introduction to expected return modeling and why it matters for financial planning.  (0:00:25) The importance of volatility, correlations, distribution shape, and time-series behavior in portfolio projections.  (0:01:26) How Scott Cederburg's research on block bootstrapping influenced PWL's thinking on simulations.  (0:02:03) Introduction to Columbia Engineering student John Yang and the industry research collaboration.  (0:03:30) How Conquest Planning allows PWL to upload custom return simulations.  (0:04:05) A new PWL client's detailed reasoning for moving from DIY investing to working with an advisor.  (0:06:22) Why financial planning and Monte Carlo simulations were central to the client's decision.  (0:07:22) Cross-border financial complexity and the value of professional advice.  (0:08:03) Estate planning, cognitive decline, and the role of trusted financial relationships.  (0:10:02) Research on cognitive decline and its impact on financial decision-making.  (0:12:00) Delegation, accountability, and reducing mental overhead through advisory relationships.  (0:13:47) Why the client chose PWL specifically and the appeal of evidence-based investing.  (0:15:25) Ben and Braden discuss the perceived disconnect between online discourse and demand for AUM advisors.  (0:16:12) Overview of PWL's methodology for estimating expected returns across asset classes.  (0:17:05) How PWL combines historical returns with market-implied expected returns.  (0:18:07) The use of factor premiums and expected return composition in taxable projections.  (0:18:48) Why PWL previously relied on Gaussian multivariate normal distributions for simulations.  (0:19:41) Arithmetic vs. geometric mean returns and why the distinction matters.  (0:21:01) A simple example illustrating volatility drag.  (0:23:29) Why diversification benefits must be incorporated into expected portfolio returns.  (0:25:15) How correcting portfolio math improved expected return estimates by 20–30 basis points.  (0:27:12) Transition to John Yang's interview and introduction to synthetic data generation.  (0:30:07) John explains the limitations of Gaussian return assumptions.  (0:31:04) Why realistic sequences of returns matter for retirement planning.  (0:32:16) Empirical evidence that returns are not truly random.  (0:33:25) The three modeling challenges: unique asset behavior, realistic co-movement, and tail risk.  (0:37:49) Separating marginal distributions from dependency structures in the modeling process.  (0:38:48) Using a t-copula to better model asset co-movement during market stress.  (0:39:39) Why historical data alone struggles to capture rare crisis events.  (0:40:06) Applying Extreme Value Theory and Generalized Pareto Distributions to model tail risk.  (0:42:15) How Monte Carlo simulations generate many realistic future return paths.  (0:43:00) Imposing forward-looking expected returns and volatility assumptions onto the simulations.  (0:44:56) How the new framework better preserves skewness and kurtosis.  (0:46:38) Evaluating the new model using marginal shape, tail behavior, and co-movement scores.  (0:48:10) Why the new model significantly improved tail realism without sacrificing correlations.  (0:49:05) Future extensions including dynamic correlations and volatility clustering.  (0:50:28) Potential future use of GANs and machine learning for synthetic financial data.  (0:52:02) Key takeaway: financial planning requires realistic return paths, not just summary statistics.  (0:53:41) Braden analyzes how the new simulation framework affects financial advice.  (0:55:04) Why monthly index data produced fatter tails than long-term annual DMS data.  (0:58:47) The new model improved Monte Carlo success rates by roughly 2–3%.  (1:00:25) Sustainable spending estimates changed only modestly under the new simulations.  (1:02:27) Why the improved methodology matters more for alternative asset classes.  (1:04:25) The surprising finding that median wealth outcomes increased while mean outcomes decreased.  (1:05:47) Why Gaussian simulations can create unrealistic runaway wealth scenarios.  (1:07:20) The practical implications for estate planning and multi-generational wealth projections.  (1:08:30) Why better simulation methods are especially important for concentrated and alternative investments.   Links From Today's Episode: Meet with PWL Capital: https://calendly.com/d/3vm-t2j-h3p Rational Reminder on iTunes — https://itunes.apple.com/ca/podcast/the-rational-reminder-podcast/id1426530582.

A conversation with John Yang, President and Executive Director of Asian Americans Advancing Justice reverberates with facts and feelings. To start, we talk about the recent Supreme Court hearing on birthright citizenship, an outcome of President Trump's preoccupation with erasing this foundational constitutional right. As John explains on this episode of Power Station, this impulse is rooted in the desire to control who should and should not be considered an American. We are seeing this play out in real time in immigration sweeps and detention centers across the country. And while we do not see a lot of reporting about this, the birthright citizenship issue has a disproportionate impact on Asian Americans. In fact, about 1 in 25 people in the community would be impacted by an adverse ruling. But when John talks about birthright citizenship and his organization's broader civil and human rights mission, he is not advocating for Asian Americans alone. He collaborates with African American, Latino and LGBTQ organizations to advance together towards a more just America for all.  This value of inclusion runs deep within John and is embedded in AAJC's strategies and programs. Hear him!

From creating SWE-bench in a Princeton basement to shipping CodeClash, SWE-bench Multimodal, and SWE-bench Multilingual, John Yang has spent the last year and a half watching his benchmark become the de facto standard for evaluating AI coding agents—trusted by Cognition (Devin), OpenAI, Anthropic, and every major lab racing to solve software engineering at scale.
