PFE investing idea

Hi my dear subscribers.

Today I want to talk about PFE.

Everyone know about their products in medicine and COVID-19 vaccine. Why do I think about investing even on not short-term speculation, but for long time.
Reasons are:
+ Growth of Research and Development
+ Using short and long term investing for diversing of risks
+ Decreasing of inventories
+ Really good financial profit results (net margin - 22,94%)
+ Company pays dividends on 4,2% level
+ Stock buyback ratio is 2,4% (for 3 years), that means, that Pfizer is strong enough in her business

Maybe some moments can cause you be carefull, like growning of long-term debts. At my opinion reason is in the industry of Pfizer. Creating of medicine needs to have big Research and Development costs, with all of this tests, certificates from goverment and so on. That is why I don't think, that big debts level is not so critical (surely, it is still have influence).
