我這一段時間在重點加倉兩隻股：GOOG & AMZN.
GOOG是年初賣飛了，後來重新分析理清思路，決定買回，幾次加倉後均價$240。
AMZN比較幸運，前幾天跌得滿地找牙時，我趁火打劫進了很多，均價$213.
但是因為AMZN買得太多了，所以持倉超過了我對這隻股portfolio allocation %的分配, 所以今天早上在$222賣出了一批。將更多資金轉入GOOG@246. 我寫這一篇，是想說一個我投資時長持的心理安定法—— （1）買入價很重要，（2）portfolio allocation很重要，（3）當然，最重要的是買入一個自己有conviction的好公司，（4）不要鋪得太開，我手上除了幾隻ETFs, 個股不超過10個，這樣便於管理。
再補充一點：假如AMZN跌到$200 - 180 -160, 我會繼續買入。

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.
