Examining arbitrage opportunities among Canadian cross-listed securities : evidence from stock and option markets

Li, Zhen 21 September 2009
A cross-border listing occurs when an individual company establishes a secondary listing on a stock exchange abroad. In this paper, we analyze and compare the arbitrage proportions (through violation of put-call parity) of publicly traded cross-listed Canadian stocks, and those of industry and performance matched US domestically-listed shares. The cross-listed Canadian stocks are listed on both of the Toronto Stock Exchange (TSX) and either the New York Stock Exchange (NYSE) or the American Stock Exchange (AMEX).<p> Arbitrage opportunities exist when put-call parity is violated. Our empirical results show that in most circumstances, both domestic put-call parity and cross-border put-call parity hold well in the two countries. However, in Canadian market, a high proportion of arbitrage op-portunities could be detected in closing prices on the particular date of March 14, 2007.<p> On March 14th 2007, many of the observations in the Canadian market contained arbi-trage opportunities. Both domestic and cross-border put-call parity was violated. However, we fail to find the same phenomenon in the US market. In the US market, opportunities for arbitrage occur rarely and sporadically. We also find that the option trading volume in the Canadian market is lower than that in the US market, and during dramatic market price drops, the option trading volume remains at a low level.

Price Discovery Across Option and Equity Prices

Kane, Hayden January 2014 (has links)
This paper measures the channels by which private information is incorporated in prices in the equity and option markets. Using a mispricing events approach and conditioning on the option market being the cause of the mispricing event, I analyse the subsequent behaviour of both the options and equity markets and I find that options markets play an important role in the price discovery process. When conditioning on option caused mispricing events, the equity price adjusts towards the options price to reconcile the prices. I find that around 40% of the option caused mispricing events contain information, and the equity prices adjust 35-40%, depending on the exchange, of the maximum discrepancy before prices reconcile. When the equity market causes the mispricing, the option market follows due to the autoquote mechanism. Additionally, I use Monte Carlo to assess the suitability of the Hasbrouck (1995) Information Share and Gonzalo-Granger (1995) Component Share measures in the option-equity context. I find that neither metric is suitable, however the Putnins (2013) Information Leadership metric is and the options market has on average a 35% information leadership share.

Reconceptualising the capital adequacy requirement of short-term insurance companies within the call option framework

Britten, James Howard Christopher 08 December 2011 (has links)
Conventional wisdom decrees that in order for insurers to provide cover, they require capital. One of the many methods of calculating capital requirements of short-term insurers is the insolvency put option framework. This technique was originally introduced by Merton (1977). The general argument is that bankruptcy occurs when shareholders exercise a valuable put option. Indeed, the corporation was introduced to protect shareholders from, mainly contractual, liabilities of persons who trade with the corporation. The corporation thus introduced the idea of limited liability of shareholders or as is often called the corporate veil. However, if a company defaults on its debt then equity holders have decided to allow an embedded call option to expire unexercised. As a result shareholders will behave as if they in fact hold a call option, which creates a different incentive than that suggested by the insolvency put idea. This study examines the role of capital and the influence of the insolvency put option within a short-term insurer. Specifically, it is argued that capital is not the cornerstone of a short-term insurer. Moreover, using Brownian motion and Itō calculus as well as continuous time financial models a more complete mathematical description of an insurance company is articulated by explicitly taking the embedded equity call option into account.

Finns det möjlighet till arbitrage på VINX30 aktieindexoptioner? : en empirisk undersökning

Lindström, Thomas, Stenkvist, Cecilia January 2008 (has links)
Optioner är ett instrument som investerare kan använda för att spekulera i framtida upp-eller nedgångar på olika tillgångar. Om dessa optioner är felprissatta finns det möjlighet att göra riskfria vinster med hjälp av Stolls köp-säljparitet. Tidigare studier visar att marknaden inte alltid är effektiv i sin prissättning av aktieindexoptioner och att det därigenom finns möjlighet till arbitrage. Denna studie undersöker huruvida marknaden är effektiv i sin prissättning av VINX30 aktieindexoptioner, d.v.s. finns det möjlighet till arbitrag på VINX30 aktieindexoptioner? / Options are an instrument which investors can use to speculate in future pricemovements on different assets. If these options are misspriced there are an opportunity to get riskfree profit by using Stolls put-call parity. Earlier research shows that the market sometimes is inefficient when pricing stock index options allowing arbitrage. This study investigate whether the market is efficient in the pricing of VINX30 stock index options, i.e. are there arbitrage opportunities on VINX30 stock index options?

以羅吉斯與類神經模型辨別台灣選擇權與期貨市場間的有效套利機會 / Distinguishing valid arbitrage opportunities in Taiwan option and future market by logistic regression and artificial neural networks

宋鴻緯, Sung, Hong Wei Unknown Date (has links)
本研究在考慮交易成本的情況下,利用羅吉斯模型、類神經模型以及其兩者的混合模型建立一分類器,用以識別台灣選擇權與期貨市場中違反買權賣權平價等式的套利訊號。由逐筆成交資料的實證結果顯示,無論在金融海嘯(2007)、景氣復甦(2008)或是平穩時期(2012~2014)時,就識別率來說三種模型相差不大,但就獲利性而言混合模型有略優於其他兩者的表現。 / Considering the transaction cost, we establish a binary classifier system by logistic regression, artificial neural networks and hybird model with aboves. The system is used for distinguishing valid arbitrage opportunities which violated put call parity in Taiwan option and future market. By tickdata, we find that, although three models has same accuracy on classification almostly, hybird model is grater then the others in profitability no matter in depression(2007), boom(2008) or business steady state(2012~2014).

以變異數比率法檢定指數選擇權之買賣權平價理論——馬可夫狀態轉換模型之應用

秦秀琪 Unknown Date (has links)
本研究目的在於探討Put-Call Parity(PCP)所隱含的買權、賣權與標的資產間的價格變動關係。藉由探討PCP偏差程度的動態行為,推論若PCP的偏差為隨機漫步過程,則無法達到長期穩定,隱含PCP的廣義關係無法成立;反之,若PCP的偏差具有回歸平均特性,表示長期會達到穩定狀態,則PCP的廣義關係成立。 在研究方法上本文以變異數比率法檢定指數選擇權的PCP偏差是否為隨機漫步過程,採用隱含利率和實際無風險利率的差代表PCP的偏差程度,利用馬可夫轉換模型描繪PCP偏差的動態行為,並使用Gibbs Sampling演算法說明參數的不確定性。 本文以S&P500和DAX為研究標的,並探討股利不確定性是否影響PCP廣義關係,得到下列結論: 1、 對於S&P 500指數選擇權而言,不論是以日資料或週資料估計VR,S&P 500的PCP偏差都無法提供回歸平均的證據,隱含S&P 500的PCP廣義關係無法成立。 2、 對於DAX指數選擇權而言,檢定日資料的結果發現,DAX之PCP偏差在長期時(40~50日)有明顯的回歸平均的證據;而在檢定週資料時,使用原始資料法在90%信心水準下,不論取任何lag都可拒絕虛無假設,使用標準化資料則無法提供明顯的回歸平均證據。 3、 比較S&P 500和DAX,檢定日資料與週資料的結果都發現,DAX的p-value都比S&P 500小,並且S&P 500的PCP偏差都無法提供回歸平均的證據,而DAX有明顯回歸平均現象,隱含在消除股利的不確定性後,指數選擇權PCP的廣義關係式成立之證據較強烈。

Menové opcie / Currency options

Tomovič, Tomáš January 2008 (has links)
Subject of the submitted thesis is the issue of currency options. The aim is the detailed analysis of currency options forcefully on dealing, characteristics, methods of pricing and their use for hedging strategies. The first part of the thesis presents an introduction into the option theory. The second part is about dealing, pricing and arbitrage relationships of currency options. In this part are two option pricing model extracted -- the binomial options pricing model for pricing currency options and the Garman-Kohlhagen model for pricing European currency options. In the third part is an example for a currency put option hedging strategy.
