Groupon’s IPO by the numbers (infographic)

More than a fifth of people who bought Groupon stock on the day of its initial public offering sold their shares the same day.

That fact, among other interesting tidbits, is revealed by research conducted by SigFig, which tracks more than $20 billion in customer investments across more than 65 different brokerages.

SigFig assembled the infographic below, showing Groupon’s timeline to IPO as well as data about what happened to its stock after it started trading. For instance:

• The offering price was $20, but you couldn’t get it that cheaply unless you were on the inside (just look how tiny the $20 slice is on the pie chart below showing purchase prices).
• The stock opened at $28 and the average purchase price on IPO day was $28.17. (GRPN is trading a bit above $24 today.)
• Despite the large number of people buying and then selling on the same day, nobody really struck it rich. The average same-day return was -3.3 percent.
• Pandora day traders did even worse on that company’s IPO day. The average return for same-day flippers was -8.52 percent.
• On the other hand, if you were lucky enough to buy and flip LinkedIn stock on its initial day, you probably did better: The average return for that stock was 7.1 percent.
