Here are some more data confirming a stock market correction.
The consumer staples ETF (XLP) began to outperform the consumer discretionary ETF (XLY) on January 25th while the S&P500 continued to move higher. As the ratio (red time series) moves lower it generally reflects growing caution among investors, who moving into defensive plays, and has been a fairly good early warning indicator of risk aversion.
We’ve also included a chart with a longer time period. Note how the ratio led the S&P500 (SPY) during collapse and was first to bottom.

Not perfect, not always reliable, and the timing makes it difficult to trade, but it does help in formulating a trading view.
