How to prevent anchoring from sinking your portfolio
One tricky thing with investing is that things are always changing. An indestructible monopoly one day (can you believe that Microsoft (MSFT) was almost broken up by the government over the bundling of Internet Explorer with Windows?) can find itself suddenly behind the times and struggling to catch up a mere decade later. Similarly, sometimes all it takes is one or two amazing products to turn a tiny and irrelevant company like Apple (AAPL) into the largest publicly traded company in the world over the same time period.
