When it comes to choosing stocks, it really comes down to how you invest. There are some companies that are worth for long term and some trading at short term will give you higher profits.
Long term
Usually these are the blue chips companies or companies you believe it will grow in. For example, you look at how AMD is winning Intel  $INTC.US$  on the news and your trust for AMD  $AMD.US$  is better. Then you can enter one of them as long term.
Short term
For short term, usually I would check on social media for the trends or how the community is moving. Most famously is wallstreetbets but this comes with its risk.
These are how I pick my stocks but then again I’m just a newbie. If theres any more advise I am willing to learn.

从全球芯片短缺到季度高收益，我觉得我们还没有看到销量下降的影响，因为芯片制造商仍然有一些盈余。就短期而言，我认为可以投资于稳定的科技股，比如 $AAPL.US$或 $TSM.US$但一旦全球出现短缺，我们就会看到下降。专家们怎么看？
