How do you currently analyze a company before investing?

Hi
I’m wanna know how do u understand and research a company before investing.

• What sources do you usually go through? (annual reports, earnings calls, news, etc.)
• How much time do you typically spend analyzing one company?
• What part of the process takes the most effort or feels frustrating?
• Do you actually read full reports, or rely on summaries / other tools?

I have been investing in CSE ( Colombo Stock Exchange ) since 2023, and invested around LKR 380K but to be honest, i just look at the tradingview grapghs and invest or ask the brokerage guy… so,, I now need to learn the market. I blive reading latest news also part of this right ?
