The NASDAQ 100 index is currently showing positive momentum as it prepares for NVIDIA's earnings report. This comes after a period of volatility caused by geopolitical tensions.

After a series of gains in the past three sessions, the index is aiming to reach the highs seen in early October, which are around 21,200. However, if the index closes below 20,300, it could indicate a potential decline towards the late October level of 20,000.

On the other hand, the Dow is holding steady after briefly dropping below 43,000. Sellers are watching for a possible reversal that could push prices back down, potentially leading to lows in late October just under 42,000.

In Europe, the DAX 40 index is trying to stabilize after a decline that briefly took it below 19,000. If the index closes above last week's high of 19,300, it could suggest a sustained rebound, with potential gains targeting the October highs around 19,700.

This short-term pullback is in contrast to the longer-term rally, indicating that it may be a correction within a broader upward trend.
