When the Nasdaq closed on Friday, June 28, Chinese social network YY had their shares priced at 69.69. Searching 'YY" on Google became a viral joke over the weekend until the market reopened Monday morning and the price changed.
On Saturday, June, 29, Reddit user Alopez2987 posted 'Type yy into google' on /r/wallstreetbets and the post blew up. Over the weekend multiple posts notifying people of the joke gained momentum on Twitter and Instagram. Their stock price is currently at 70.74, but it was a 'nice' joke while it lasted.
