link Another clueless article IMO. It's from ComputerWorld, probably written by a nerd or geek. Amazon just passed Alphabet (Google) yesterday to become the world's second most valuable company, after #1 Apple. Yes, Apple! I was surprised by that too. Amazon already passed Microsoft (IIRC #4). Amazon has been doing poorly since Tuesday but I'm confident they will return to their approx. $1,600 high sooner or later, and continue the long climb. I am of course focused on Amazon since I have a large part of my net worth on Amazon's nose. I quit watching the rest of the market when I sold off my Apple and eBay late last week and bought more Amazon Monday. If it returns to this week's low I still have some money in my brokerage account and might buy more Amazon (and forget about neat numbers). I have the proceeds from the sale of my condo coming in tomorrow but it takes me a couple days to move money into my brokerage account and the check from the escrow company will probably have a hold on it for a while anyway. I'm pretty sure I'm in deep enough that it wouldn't be advisable to get any deeper. You know the sayings about eggs and baskets. ETA: I became intrigued by the idea of the biggest companies and decided to research it a bit. I was surprised there was no real time list I could find, and surprised that things seem to be in such flux say perhaps beginning of 2017 to present. Yes folks, this really is a horse race, and they haven't reached the stretch yet. They have been rising and falling like crazy the last 15 months. The one steady trend I can see is ... yep, you guessed it. My horse is nosing its way to the leader of the pack. (It might still be #1 today, I can't find a real time list. The articles say Amazon was #1 on Tuesday. Presumably the author have real time data. I don't.) I think in another month or two this silly business will be over and nobody will dispute that Amazon really is #1. All I can say is good luck Alphabet, Amazon is going to eat your lunch. (I hope there is no penalty for mixing too many metaphors.) ETA: (again) I looked up a few likely stocks and here's my list of market cap: 863.44B AAPL 760.94B AMZN 749.96B GOOG 705.53B MSFT 488.00B FB 219.13B ATT Note that I don't have the list of all the contenders.
