LinkedIn Helped By Lack of Shorting, Put Options There are no shares to short anywhere so it can only go one way, which is up Traders can t buy put options either, since the options market doesn t get a crack at LNKD until next week Douglas Estadt of Rand Strategic Partners Interview on WSJ.com - (19 May 2011)
When are options listed after IPO? 600 500 400 300 200 Never optioned After 36 months 13-36 months 7-12 months Within 6 months 100 0 1996 1997 1998 1999 2000 2001 2002 2003 2004 2005 2006 2007 2008 IPO issuance year Within 6 After 36 Never 7-12 months 13-36 months All IPOs months months optioned 1996-2008 396 373 418 274 1117 2578
Research questions 1. What are the consequence of option listing on the equity firms that have recently gone public? Why? Is there a trading strategy? 2. Which factors determine when options are listed after the firm goes public?
Main result: Impact of option listing on IPO stocks Weekly CAR (%) around option listing date Raw returns Nasdaq-adjusted returns Small firmadjusted returns Matching firmadjusted returns Weeks relative to option listing date
Motivations IPO stocks underperforms in the long-run, i.e. short-run overvaluation (Ritter (1991)) Why?? Ritter (JF, 1991)
Motivations Short-run overvaluation Why?? IPO stocks are subject to significant: 1. Shortsale constraint. Houge, Loughran, Suchanek, and Yan (2001), Ljungqvist, Nanda, and Singh (2006), Geczy, Musto, and Reed (2002) Option listing relaxes shortsale constraint, e.g. Figlewski and Webb (1993), Danielsen and Sorescu (2001) 2. Heterogeneous investors belief. Miller (1977), Chemmanur and Krishnan (2012) Options market improves price discovery via increasing investors participation, e.g. Easley, O Hara, Srinivas (1998)
Main findings 1. IPO stock underperforms immediately after option listing Informed speculators put options to synthetically short the underlying IPO stock Short-interests trading activity triples Insiders aggressively sell their shares Significant profit from buying newly-listed put options 2. Exchanges tend to early-list options on IPOs that are: Venture capital backed Taken public by less reputable underwriter
Data and methods Databases: SDC platinum, OptionMetrics, CRSP, Compustat, Thomson s insider trading, I/B/E/S, First Call, Shortsqueeze. IPO sample: Focus on US offerings between 1996 to 2008 Exclude REIT, Closed-end funds, non-ordinary shares, etc. Abnormal return benchmark : (1) Firm matched by industry and size (Matching firm-adjusted) (2) CRSP-value-weighted NASDAQ ( NASDAQ-adjusted ) (3) Lowest decile of NYSE market index ( Small firm-adjusted )
Remaining tasks 1. Data and methods 2. Impact of option listing on IPO returns 3. Determinants of option listing on IPOs 4. Trading strategy 5. Explaining post-option-listing returns

Extended Cox model We model time-to-list : number of months from IPO issuance to when options are introduced IPO variables: Percent shares locked up, Proceeds size, Lockup flag, Venture backed, First-day-return, etc. Time-varying covariates (Mayhew and Mihov (2004)): Shares turnover, Market cap, Volatility, Momentum

Buying put options on IPO stocks Can we make profit from this phenomenon? Yes! Put payoff S Buy newly-listed put options on IPO stocks ( pick OTM contract and longest maturity available ) Hold them to maturity 6% average monthly returns after transaction costs
Excess returns from buying puts after transaction cost Higher returns for the strategy that focuses on: OTM/Long-maturity puts Venture-backed IPO firms Firms that receive options listing early IPOs with large first-day pop ITM OTM Remark: This is an event study result

Synthetic shorting using put options In ordinary short selling: Short seller must find an existing owner who is willing to lend her the share Lending fee can be very high for hard-to-borrow stocks, i.e. IPO. (Geczy, Musto, and Reed (2002)) When an investor buys a put option: Market maker hedges his position by short selling the underlying shares But he can do this cheaply! (Reg SHO) Empirical prediction: Short interests level in the security should increase tremendously
Changes in short interest ratio: Relative to event month -4
Insider selling post-option listing Why do we observe persistent underperformance up to a year after options listing? Insiders sells their shares in anticipation of price decline Certain insiders, e.g., VC, might face greater pressure than others Empirical prediction: Percentage shares held by insiders significantly decline for several months after options listing
Changes in insider shares holding: Relative to event month -4
Conclusions 1. IPO stocks underperform after options have been listed. 2. Option listing improves price discovery of newly public firms, and their timing affects IPO long-run performance. 3. Buying newly listed long-maturity put options on IPO stocks yields up to 6% return per month after transaction costs.
Option listing on CBOE IPO: Jun 18th 2010 Option listed: Jun 23rd 2010
Other on-going research projects 1. Market illiquidity: Crash risk: How does market illiquidity impact timevarying crash risk? Liquidity spillover: How does market illiquidity propagate between the equity and derivative markets? 2. Investment & security analysts: Older, Slow, and Wiser? Does decision-speed determine stock-picking ability? Paying for talent: Do funds that charge more hire better stock-picking experts?
