From the perspective of moving averages, AMD's 5-day moving average currently stands at $622.76, the 10-day moving average at $572.88, and the 20-day moving average at $528.10. The short-to-medium-term moving averages maintain a bullish alignment, with the stock price continuing to trade well above major moving averages, indicating that the overall uptrend remains intact.

In terms of momentum indicators, the 14-day RSI stands at 73, entering overbought territory. This indicates a rapid short-term gain, increasing the risk of high-level consolidation or profit-taking. As for the MACD, the MACD line remains above the signal line, with the histogram staying in positive territory, suggesting that the current upward momentum has not significantly weakened.

In the short term, immediate resistance on the upside is near the previous high of $640. If the stock continues to set new all-time highs, it will test the 0.618 Fibonacci extension level at $666. If it can hold firmly above this level, it will open up upside room toward $700-$732.

On the downside, initial support is near $620-$623, close to the 5-day moving average. A breakdown below this level could lead to a further retest of the $600 psychological mark. Further down, more crucial medium-term support lies around the previous breakout zone of $584-$585.
