The share price appears unable to break out above the historic resistance level at 170.00, which represents a very strong bearish signal.
Moreover, the price action has recently established a broad 1-5 impulse wave pattern, as postulated by the Elliott Wave Theory, as well as having developed an Ascending Wedge. Both of these developments confirm the bearish expectations.
Finally, yesterday's trading session resulted in the creation of a Shooting Star candle, which could be a precursor to an imminent reversal.
Overall, there seems to be a very strong confluence of bearish indications at present.
The 23.6 and 38.2 per cent Fibonacci retracement levels represent the most likely targets for such a dropdown.
