In the early morning of December 23 (Friday), East coast time in Australia, the US stock market was affected by a sharp drop in technology stocks, and the three major stock indexes turned down again, of which the Nasdaq fell the most (-2.18%) and the Dow fell the least (-1.05%), which shows that the current market sentiment is once again linked to the future interest rate environment, and considering that the end of the year is coming. Risk aversion (temporary closing) by many market participants has also exacerbated the tech downturn.In terms of technical analysis, although it has been falling for nearly two weeks, the NAS100 made a key move in the late session - landing safely near the 10,800 mark formed in early October, and then rebounding to near 10,970. A perfect bottom-hunting opportunity for traders who regularly read the AETOS Daily Currency Review (10,800 position pre-set entry). At present, the fundamentals of the NAS100 are still not clear, so traders should take the technical price as a reference to the corresponding short and medium term layout.In currency markets, non-US currency pairs generally lost momentum overnight, with the pound moving further lower, the euro finding support near 1.05780, and more noteworthy is this week's "burst" pair - USDJPY, USDJPY, USDJPY. The latter has gradually recovered to around 132.400 after the sharp fall triggered by the boj decision this week.In addition, the USDJPY has formed an upward triangle shape, judging from the technical analysis theory, is the standard trend of the price is expected to break upward, if the breakthrough is formed, then traders can also understand that the yen traders must re-price, and the breakthrough price point may become the support level of the USDJPY for some time in the future.
