US30 DOWNTREND?US 30CAPITALCOM:US30kurolisuUS30 has been in a prolonged uptrend for quite some time. The 200-day moving average has flattened out, and among its constituent stocks, underperformers such as Microsoft and IBM have begun to appear. This suggests that, triggered by some catalyst, the index could start to decline. In addition, the 49,800 level had been acting as an upper resistance line, while 49,280 functioned as a support line—but it remains to be seen how long this structure will hold.
