我这一段时间在重点加仓两只股：GOOG & AMZN.
GOOG是年初卖飞了，后来重新分析理清思路，决定买回，几次加仓后均价$240。
AMZN比较幸运，前几天跌得满地找牙时，我趁火打劫进了很多，均价$213.
但是因为AMZN买得太多了，所以持仓超过了我对这只股portfolio allocation %的分配, 所以今天早上在$222卖出了一批。将更多资金转入GOOG@246. 我写这一篇，是想说一个我投资时长持的心理安定法—— （1）买入价很重要，（2）portfolio allocation很重要，（3）当然，最重要的是买入一个自己有conviction的好公司，（4）不要铺得太开，我手上除了几只ETFs, 个股不超过10个，这样便于管理。
再补充一点：假如AMZN跌到$200 - 180 -160, 我会继续买入。

Why Alphabet (GOOGL) Stock Is Trading Lower Today？
What Happened?
Shares of online advertising giant Alphabet (NASDAQ:GOOGL) fell 3.2% in the afternoon session after privately held competitor OpenAI announced a new online search browser (ChatGPT Atlas). This new product, integrating advanced AI directly into the browsing and search experience, represents a direct, major competitive threat to Google's most profitable assets: the Chrome browser and the Search advertising engine. This news likely prompted some investors to take profits in GOOGL, which was near an all-time high, as the market re-priced the risk associated with this intensified AI "war" for internet dominance.
The stock market overreacts to news, and big price drops can present good opportunities to buy high-quality stocks. Is now the time to buy Alphabet? Access our full analysis report here.
What Is The Market Telling Us
Alphabet’s shares are not very volatile and have only had 6 moves greater than 5% over the last year. In that context, today’s move indicates the market considers this news meaningful, although it might not be something that would fundamentally change its perception of the business.
The previous big move we wrote about was 8 days ago when the stock gained 2.8% as investors' concerns about US-China trade tensions were eased by President Trump's more conciliatory tone over the weekend. Following a sharp market drop the previous trading day driven by trade conflict escalation, Wall Street's main indexes opened significantly higher. The Dow Jones Industrial Average, S&P 500, and Nasdaq all saw gains of over 1%. The rebound was attributed to comments made by the President on social media, where he stated the "China situation will all be fine" and that the U.S. "wants to help China, not hurt it!!!" This shift in rhetoric prompted a return to risk assets, as traders brushed aside the previous week's fears. The rally ahead of the upcoming earnings season suggests that the "buy-the-dip" mentality remains strong among investors whenever trade jitters subside.
Alphabet is up 32.6% since the beginning of the year, and at $251.16 per share, it is trading close to its 52-week high of $256.55 from October 2025. Investors who bought $1,000 worth of Alphabet’s shares 5 years ago would now be looking at an investment worth $3,167.
