nvda pltr qqq 買點區間？

The deep research logic is organized as follows: 

Okay, let's tackle this question. The user is asking about the buy point ranges for NVDA, PLTR, and QQQ. They provided a lot of data, so I need to go through each stock one by one.

Starting with NVDA. The user's references mention support and resistance levels. From the first reference, NVDA's support is $95.04 and resistance at $184.48 as of 2025-08-19. But looking at the latest price, it's $178.14, which is below the resistance. However, other sources like the news articles talk about a golden cross and potential upside to $300. Also, the 50-day moving average is around $165, and the 200-day is $137.27. The user's profile shows they like technically strong stocks, so the golden cross and moving averages are important. The support levels from the data are lower, but the current price is much higher. Maybe the immediate support is around $159, $150, and $143, but the user might be looking for more recent levels. The latest price is $178.14, so the next support after that might be around $159. But the user's question is about buy points, so the current price is near the resistance, but the golden cross suggests a bullish trend. Maybe the buy point is around the 50-day MA or the recent consolidation levels.

Next, PLTR. The support level from the second reference is $128.51 and resistance at $190. The last price is $163.63. The user's data also shows the 50-day MA at $152.3 and 200-day at $104.66. The RSI is 28.83, which is oversold. The user's profile mentions they like undervalued stocks, so PLTR might be a candidate if it breaks above the 50-day MA. The resistance at $190 is a key level. The user's stop loss and profit targets are short-term, so maybe looking for a breakout above $160 or $170.

For QQQ, the support is $427.93 and resistance at $583.32. The last price is $571.32, which is close to the resistance. The 50-day MA is $555.42 and 200-day at $515.58. The user's data shows the ETF is in a bullish trend with a golden cross. The support levels are lower, but the current price is near the resistance. The user might be interested in a pullback to the 50-day MA as a buy point. Also, the ETF's composition includes tech stocks, which aligns with the user's interest in IT and SaaS sectors.

Putting it all together, the buy points should consider the support levels, moving averages, and recent price action. For NVDA, the buy point could be around the 50-day MA or the recent consolidation levels. For PLTR, breaking above the 50-day MA or the $160 level. For QQQ, a pullback to the 50-day MA or the $550 area. The user's short-term horizon and focus on technicals mean these levels are crucial. Also, considering the user's stop loss and profit targets, the buy points should be set with those in mind.
