<prompt> Human: Im not necessarily looking for research on amazon itself I am more looking for advice on purchasing a stock that costs 1600.In general, Im paid fairly well and think I am ahead of the curve in PF. Wife and I have no student loans. Were on track for 50k in college savings for daughter. Were on track for paying off 30 year mortgage in 20 years. Retirement savings are on track as well. We have 15k cash emergency fund. Id be looking to buy this share from my own personal savings which I keep on the side wife knows about this.Back in 2009 I thought it would be wise to buy some stocks after the crash assuming theyve come back. I threw some spare money I had then when I was making 12 as much as I am now. I lost 150 on the Zynga IPO going down, cut my losses cashed it in and I ended up with single shares of Citi Group and Microsoft. Those have both climbed up over the the years and Im pretty much even excluding any trading fees or taxes.You would have think I would have learned my lesson, but I am interesting in grabbing a share of Amazon because its growth seems to be unstoppable. I dont want emotion to make decisions, but I dont want to be 10years from now thinking if I had invested 1600 in AMZN 10 years ago Id have 15k now and we could go on a nice vacation or have a nice down payment on a car. Also, I could see this stock eventually splitting and if I needed to get out of it I could probably cash out some of the shares if needed. I would be looking to ride this out at least 5 years.Tell me why this is a good idea, stupid idea, or just a middle of the road idea?  <response>: If all your other affairs and retirement plans are in order, this is fine. I think having this separate pool of money as kind of a hobby investment for something fun like a vacation is an OK idea for somebody with the interest.
