From a financial point\u0000of view, this corresponds to taking into account call option prices not only,\u0000as usual, for those call options where the respective future maturities\u0000coincide with the maturities of some exotic derivative but also additional\u0000maturities and then to study the effect on model-independent price bounds for\u0000the exotic derivative. We characterize market settings, i.e., combinations of\u0000the payoff of exotic derivatives, call option prices and marginal distributions\u0000that guarantee improved price bounds as well as those market settings that\u0000exclude any improvement. Eventually, we showcase in numerous examples that the consideration of\u0000additional price information on vanilla options may have a considerable impact\u0000on the resultant model-independent price bounds.","PeriodicalId":501355,"journal":{"name":"arXiv - QuantFin - Pricing of Securities","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-07-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"138522572","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The\u0000pseudo maximum likelihood setting under a large cross-sectional dimension $n$\u0000and a fixed time series dimension $T$ relies on a diagonal $T times T$\u0000covariance matrix of the errors without imposing sphericity or Gaussianity. We\u0000outline the asymptotic distributions of the latent factor and error covariance\u0000estimates as well as of an asymptotically uniformly most powerful invariant\u0000(AUMPI) test based on the likelihood ratio statistic for tests of the number of\u0000factors. We derive the AUMPI characterization from inequalities ensuring the\u0000monotone likelihood ratio property for positive definite quadratic forms in\u0000normal variables. An empirical application to a large panel of monthly U.S.\u0000stock returns separates date after date systematic and idiosyncratic risks in\u0000short subperiods of bear vs. bull market based on the selected number of\u0000factors. We observe an uptrend in idiosyncratic volatility while the systematic\u0000risk explains a large part of the cross-sectional total variance in bear\u0000markets but is not driven by a single factor.

The abundance of\u0000information and opinions shared on social media can generate hype around\u0000certain stocks, leading to investors' irrational buying and selling decisions.\u0000This can result in an overvaluation of the stock in the short term but often\u0000leads to a correction in the long term as the stock's performance fails to meet\u0000the inflated expectations. In particular, I find that IPOs with high levels of\u0000pre-IPO investor enthusiasm tend to have a significantly higher first-day\u0000return of 29.54%, compared to IPOs with lower levels of pre-IPO investor\u0000enthusiasm, which have an average first-day return of 16.91%.
