My “system” features 3-10 minutes of quick due diligence each on a large number of new stocks. In this system, Speculative buy is quite possible. Result is unpredictable.
( In an alternative system, if you want a stability track record of stock picking, it can be improved slightly, by due diligence on CDY, dividend history, company size, analyst rating etc. )
— eg: WNS of India. Luckily I bought only $3.80
— eg: MRNA (Moderna) ..
— eg: CRBP
==== quick but not speculative
— eg: BGC partners .. I bought due to my “insider” knowledge. The stock remained underwater for years.
đŸ™‚ a bit of dividend, better than nothing.
— eg: BKCC (blackrock …).. I bought due to the Blackrock association
đŸ™‚ high CDY maintained through 2020
— eg: ICICI bank of India
