This MarketCarpet covers the month of May, which, as the sea of red reflects, has been mostly down. Users can hover over the MarketCarpet, right click the mouse and choose “show values” to see each stock’s value. A value of -12 indicates that the stock has been down all 12 days. Note that 13 days refers to 12 price changes. The energy, finance, industrials and materials sectors have the most red squares. Believe it or not, there are a few stocks with positive readings. These isolated green squares can be found mostly in the utility, consumer staples and healthcare sectors.
