Bubble Papers

1  “Super-Exponential RE Bubble Model with Efficient Crashes” 2018:  https://papers.ssrn.com/sol3/papers.cfm?abstract_id=3064668

Basic foundation of new theory on financial bubble creation, mitigation, and advantaging.  With 18 months on SSRN Top 10 list.  Including several examples on real financial bubbles showing outperformance of the strategy.

2 “Bitcoin Bubble Trouble” 2018:  https://papers.ssrn.com/sol3/papers.cfm?abstract_id=3143750

Application to the bitcoin crash with a crash prediction on December 19, 2017 successfully estimating the size of the upcoming crash.

3 “Awareness of Crash Risk Improves Kelly Strategies in Simulated Financial Time Series” 2020: https://papers.ssrn.com/sol3/papers.cfm?abstract_id=3580920

This paper looks at our method run against simulations of price data showing how assuming prices consist of Brownian motion plus jumps oscillating around a normal price that can provide strategies with successful outperformance and the method is robust in the parameter estimation.

4 “Crash-sensitive Kelly Strategy built on a modified Kreuser-Sornette bubble model tested over three decades of twenty equity indices” 2020:  https://papers.ssrn.com/sol3/papers.cfm?abstract_id=3708035

This paper looks at a slight modification of the original strategy and how well it outperforms on 20 real equity price indices over a period of 30 years.  More specifically it outlines the rational for picking the parameter and window sizes.

5 “Efficient Crashes Optimization at a Large Fund in India” 2021:  Forthcoming:  A version is currently available on request.  The final version will be published shortly showing the outperformance of a large mutual fund in India using the ECO strategy.

10 December 2016 News: Prof. Dr. Jérôme Kreuser will speak on bubbles, their prediction, quantification, and mitigation at the QWAFAFEW (Quantitative Work Alliance for Applied Finance Education and Wisdom) meeting on January 24 in New York. Bubbles are percolating and yes, many are quantifiable. We discuss and debate theory and empirics.

10 December 2016 News: RisKontroller Global is now providing bubble prediction, quantification, and mitigation analytics to SBI Funds Management Private Limited which is a Joint venture between the State Bank of India (SBI) and AMUNDI of France.

10 October 2016 News: Stijn Claessens (Now at BIS) and Jérôme Kreuser developed an asset and liability management model for Norway’s Government Pension Fund Global and presented a paper on it at the Central Bank Reserves and Sovereign Wealth Management Conference in Frankfurt in 2008. The model was calibrated prior to the Lehman collapse. We predicted an expected value of the portfolio to September 2016 of NOK 7.53 trillion, which is recorded in the conference proceedings paper (Reference below). Eight years on we were right on. The published paper is available in the conference proceeding, in ResearchGate, or from me.

Reinsurance Portfolios  and Climate Risk

Additional Papers coming soon.

Jerome Kreuser and Morton Lane (2007) in this Optimal-Insurance-and-Reinsurance-Portfolios paper on  discuss their optimization procedures to generate underwriting portfolios, maximizing expected returns which are perfectly aligned with their stated risk preferences. Similar objectives apply to those who use simulation or DFA techniques.  However, beyond the optimal portfolio itself, optimizers as part of their output also generate marginal economic signals, such as “implied” or “risk adjusted” probabilities which are important but underused and often misunderstood management tools. The purpose of this paper is to further illustrate the power of those economic signals.

Himadri Bhattacharya discusses the implications of RBI’s fat dividend payout to the government and the implications of risk management for RBI.  The article is from the Chennai BusinessLine, September 12, 2019.

Kreuser, Jerome and Didier Sornette.  2018 (updated).  “Super-Exponential RE Bubble Model with Efficient Crashes”, Submitted for Publication in the European Journal of Finance and under review.  We propose a dynamic Rational Expectations (RE) bubble model of prices with the intention to exploit it for and evaluate it on optimal investment strategies. Our bubble model is defined as a geometric Brownian motion combined with separate crash (and rally) discrete jump distributions associated with positive (and negative) bubbles.  We have tested and include in the paper the analysis of our bubble model on several historical jumps.  A recent version of the paper is available Efficient Crashes Paper Version 4-June-2018.
