You're living in a pipe dream if you think a data analytics company will become the biggest company in the world.
well if it really is then i hope it turns around somewhere soon. As of now, it's looking like 0% for the first day, and even that is an artificial level supported by the underwriters of the IPO. I'd cut your losses, get out soon, and wait until the stock corrects somewhere lower, mid-20s or even below.
There are hedge funds and banks who NEED this stock to go up. They bought in at 38. This thing will hit 55 way before it hits 25.
