The document provides background information on the 2012 UBS rogue trading scandal. It discusses UBS's history and previous controversies. It describes how trader Kweku Adoboli made unauthorized trades that ultimately lost UBS $2 billion. The scandal led to executive resignations and damaged UBS's reputation. It also lowered credit ratings and market share for UBS. The document raises questions about preventing future scandals and discusses lessons around managing moral hazard and operational risk.

master thesis presentation for pricing theory under negative interest rate en...Stephan Chang
This document contains a mix of text, numbers, formulas and code snippets related to quantitative finance modeling. It discusses topics like derivative pricing under negative interest rates, the SABR model, implied volatility, and mean reversion. Various formulas are presented for pricing derivatives, calculating implied volatility, and estimating parameters for models like SABR.
This slide is presented in Management College of Innsbruck, Austria, 2015. The topic is referred to Social Enterprise in Taiwan. Three cases are included in this presentation.
Solomon Asch's conformity experiments showed that people are inclined to conform their opinions to those of the group, even when the group's opinion conflicts with objective evidence. This tendency towards herding behavior has also been observed in individual investors. Studies of retail brokerage data found evidence that buying and selling decisions of individual investors are highly correlated and influenced by past stock returns, even when not driven by institutional investors, taxes, or risk preferences. The herding causes investors to concentrate their buying in fewer stocks than their selling and to be net buyers of stocks with unusually high trading volume. As a result, individual investors have the potential to systematically affect asset prices through their correlated behavior.
Hedging or market timing? selecting the interest rate exposure of corporate d...Stephan Chang
1. The document examines how firms choose the interest rate exposure of newly issued debt. It analyzes whether firms are hedging interest rate risk or timing the market.
2. Empirical analysis of debt issuances by chemical firms from 1994-1999 finds that firms' cash flow sensitivity to interest rates does not predict their choice of fixed or floating rate debt.
3. Firms are more likely to issue floating rate debt when yield spreads are higher, indicating they are timing the market rather than hedging firm-specific risks. The findings suggest firms manage macroeconomic and industry risks rather than hedging internal risks.
LTCM's case in 1998 would be presented in this slide.
It's my mid-term project at NCCU, Money and Banking department, for the course of " Option- Theory and Application. "
High frequency trading for the flash crashStephan Chang
The document analyzes data from the "Flash Crash" event of May 6, 2010, where major stock market indices experienced an extraordinary decline and recovery in a short period. The researchers find that:
1) High frequency traders (HFTs) did not cause the Flash Crash and did not hold large enough positions to influence prices significantly.
2) The crash was triggered by a large sell order of 75,000 futures contracts worth $4 billion.
3) During the crash, HFTs traded faster but followed the same strategies as normal days, while intermediaries were caught on the wrong side of price moves.
