The gravestone doji candlestick that appeared today on the SPX signals some potentially serious bearish implications for the broader markets, especially considering the interday test and failure at the 20day ema coming on the heels of yesterday's break below the 3 month uptrendline (not drawn, get out yer rulers, lol). A break and close below yesterday's session low (1430) would bolster the bearish case, with a move below the 50day ema (1425) clinching it...the next week or so will be critical.
