Saving everyone a Google search: AMZN opened at (split adjusted) $1.49. 5 years later it was at $19.47. Over that span, it maxed at $106.69 (Dec 1999).

it went from $2 to $16 (split adjusted). The real difference is that it was much much smaller at IPO, meaning it's pretty much impossible for FB to continue generating outsized returns whereas Amazon actually did much better from 5-10 or 10-15 than FB possibly could.
