This paper investigates whether the overpricing of out-of-the money single stock calls can be explained by Tversky and Kahneman's (1992) cumulative prospect theory (CPT). We argue that these options are overpriced because investors overweight small probability events and overpay for such...

This paper investigates whether the overpricing of out-of-the money single stock calls can be explained by Tversky and Kahneman's (1992) cumulative prospect theory (CPT). We hypothesize that these options are expensive because investors overweight small probability events and overpay for...

We uncover new return predictability in the cross-section of delta-hedged equity options. Expected returns of writing delta-hedged calls are negatively correlated with current stock price, firm profit margin and profitability, but positively correlated with firm cash holding, cash flow variance,...

Due to their short lifespans and migrating moneyness, options are notoriously difficult to study with the factor models commonly used to analyze the risk-return tradeoff in other asset classes. In-trumented principal components analysis (IPCA) solves this problem by tracking contracts in terms...

In incomplete markets, risk judgments regarding options are necessary as options cannot be replicated by using the underlying stock and the risk-free asset. How are such risk judgments formed? Underlying stock risk is a natural starting point for call option risk as the two assets pay off in the...

In recent literature it is claimed that BitCoin price behaves more likely to a volatile stock asset than a currency and that changes in its price are influenced by sentiment about the BitCoin system itself; in Kristoufek the author analyses transaction based as well as popularity based potential...

We endorse the idea, suggested in recent literature, that BitCoin prices are influenced by sentiment and confidence about the underlying technology; as a consequence, an excitement about the BitCoin system may propagate to BitCoin prices causing a Bubble effect, the presence of which is...

In informationally efficient financial markets, option prices and this implied volatility should immediately be adjusted to new information that arrives along with a jump in underlying's return, whereas gradual changes in implied volatility would indicate market inefficiency. Using...

The investor overconfidence theory predicts a direct relationship between market-wide turnover and lagged market return. Whereas previous research has examined this prediction in the equity market, we focus on trading in the options market. Controlling for stock market cross-sectional...
