In terms of Elliott Waves Sequence, we could have two forms: Wave 3 (W3) is the strongest or future Wave 5 (W5) if W3 is similar to Wave 1 (W1) in rise size.
Option 1: W3 leading us to $1.78
When W3 is the strongest, its rise is normally 1.618 fold of W1, which means 82c would be expected, as such, ISX would travel to circa $1.78. Of course this journey would not be a straight line.
Option 2: W5 targeting >$2.12
If W3 really stops at $1.49 and we are in corrective Wave 4 (W4) with dip to $1.3, W5 will start when ADI/4C arrives, then brings us to >$2.12. As W3 = W1 (51c both), W5 would be at least 1.618 fold of W3, i.e. 82c.
