Not all stocks can be bought on bad news, some can but some cannot.
As I have said several times, NVDA and TSM can buy at low, so then they are having breakthrough downward, just buy.
When AMD is falling, I told investors not to buy, for it is very hard to catch the low of a stock. Even when buys should be in the ratio of 1 to 4 or 5 with NVDA. That is when you buy 1 stock of AMD while falling, should buy at least 4 or 5 NVDA or TSM.
Just check them up in the list of Top 10 or 20 market capitalization, NVDA once on the top and AMD ranks 70.
You can buy AMD, but must prepare well to have second or third or fourth buying, I repeated numerous times, it would not be as META, TSM or NVDA can pop up at once.
How about TSLA? If you have heart disease or potential heart disease do not touch it. For the fluctuation is quite great, even if Full Self Driving will come out in summer, but now is just Feb, can your heart bear the fluctuation before June?
TSLA and TSM might also have some hindrances if Trump starts tariff war in Taiwan, Korea and Japan.
