alt Hacker News„The IPO process begins with a roadshow starting on November 10th (EST). Subject to regulatory clearance, the final IPO share price is expected to be set on November 18th (EST), and shares are expected to begin publicly trading on November 19th (EST).“
So if share price is only set one day before trading, I guess you just have that day to decide to buy if you can get allocation from your broker? I'd like to try it but I've never bought an IPO before.
