Regarding the pre-Christmas rebound, I personally favor companies that have performed strongly previously and have seen concentrated investment. After considering various options, I've narrowed it down to three: AMD, Spx, and Amazon. These companies have good earnings and haven't fallen significantly. I'm also torn between Google and Microsoft. Microsoft has the best data, but it's too expensive. Google has fallen too much, and I'm unsure about potential risks. I'm also considering betting on small-cap software to see if a miracle can happen. I'm less likely to choose storage or new cloud services because: firstly, their significant price drops have created a poor shareholding structure, making bottom-fishing risky; secondly, both have high profit margins and have overextended themselves through capacity expansion, making the financials unclear.
