Do you conduct fundamental analysis?

Those who have been navigating the stock market for a long time will know that often when news reaches our ears, it's already a situation of 'you know, I know, even the Cyclops knows.' Retail investors always receive news slower than insiders, large cap institutions, etc., but that doesn't mean we shouldn't do fundamental analysis.
For example, $Microsoft (MSFT.US)$ The recent news of a hefty acquisition of Blizzard, making $Activision Blizzard (ATVI.US)$ rise sharply by 30% in pre-market trading. Although missing out on this price increase, through fundamental analysis, it is clear that microsoft is wholeheartedly focused on its presence in the metaverse and mobile gaming. For long-term holders of microsoft stocks, this can instill more confidence in buying and holding, believing in its healthy competition with other companies, thus continuing to be one of the hot growth stocks in the future.
Sometimes news comes quickly and urgently, like $Tesla (TSLA.US)$ Previously, only unilaterally announced that Q4 revenue will exceed expectations, the stock price instantly soared by 13%, although it subsequently returned to the range of around 1000. However, we can still understand the importance of news to stock price fluctuations, as well as the level of confidence in holding a stock.
