@SentimenTrader noted this morning that stocks tended to fare poorly when the $NDX has extended streaks over it's 20dma. (currently at 46 days)  There have been 22 streaks &gt; 45 days since 1980.  If past is prologue, $SPX is likely to have some weakness for the next month or so. https://t.co/ILybYdaQNm
