There are numerous bearish patterns we can use to project a potentially important low, but the one  that I like most has three single-bar coordinates, all sharply etched.  They produce a 358.38 ‘D’ target, and although I cannot guarantee that will be where the carnage ends, it would most surely be worth bottom-fishing with a tight stop-loss.  My best-case scenario implies that the low was made yesterday at  390.63, just 0.59 points from the ‘D’ target shown in lavender. To take the offensive, bulls would need to push this vehicle to 422.47 by Thursday.  _______ UPDATE (May 17, 2:41 a.m. EDT): Bulls would need a print today at 402.85 to mount a credible offense into week’s end. At that price, the hourly chart would turn quite constructive.
