The chart below comes from Bianco Research via The Irrelevant Investor and it shows a potted history of the largest stocks in the S&P500 over the past 60 years. I always find things like this fascinating as they reinforce the understanding that your history is not the only history. Traders who began their careers this century or even in the last decade will most likely be completely unaware that the world existed before they did. This seems to be particularly true of newbies on social media who seem completely oblivious to the fact that the market had a history before they graced it with their presence. As such the current goings-on has left them completely perplexed.
