Axios told you on Tuesday that 2018 has been "brutal" for the stock market, and Bloomberg's Stephen Gandel followed up on Wednesday by saying that it's even worse than that. Above is a chart of one key valuation metric: the stock market's price-to-earnings ratio.
For the first year of the Trump presidency, valuations rose steadily. But in his second year, they've imploded and are now well below their level when he took office. The S&P 500 now trades at 17.5 times its earnings over the past 12 months. That's down 25% from the peak of 23.4 in January.
