The 纳斯达克指数 is hitting new intraday highs, currently up 134.13点（+0.78%），报17，300.82点. In the process, it has broken above a key target level at 17,238, which had served as support in mid-March (March 11, 13, and 14 — see red circles). The index is also trading above the 4月9日高点17，202.94, further strengthening the bullish case.

Looking ahead, the next major resistance is the 50%斐波纳契回撤位 of the decline from the December high, which comes in at 17,494.31. Beyond that, though not shown on the chart, is the 50日移动平均线下跌, currently at 17,732.54.

The S&P 500 is also higher, up 23点（+0.42%），报5，507.90. Yesterday, it climbed above its 200-小时均线 at 5,457.12, and is now extending gains above the 50%回撤 of its pullback from the all-time high reached on February 20. That level, at 5,491.24, now acts as short-term support. Holding above it could pave the way for further upside momentum. Staying above the 200-hour MA is a risk level for buyers looking for more upside.
