USD/JPY jumped to 148.64 last week but retreated deeply since then. Initial bias remains neutral this week first. Fall from 158.86 might have completed at 139.87 already. Further rise is in favor as long as 144.02 support holds. Above 148.64 will target 61.8% retracement of 158.86 to 139.87 at 151.60 next. However, firm break of 144.02 will bring retest of 139.87 low instead.
In the bigger picture, price actions from 161.94 are seen as a corrective pattern to rise from 102.58 (2021 low), with fall from 158.86 as the third leg. Strong support should be seen from 38.2% retracement of 102.58 to 161.94 at 139.26 to bring rebound. However, sustained break of 139.26 would open up deeper medium term decline to 61.8% retracement at 125.25.
In the long term picture, it’s still early to conclude that up trend from 75.56 (2011 low) has completed. A medium term corrective phase should have commenced, with risk of deep correction towards 55 M EMA (now at 137.17) and even below.
