I am in stock for almost 1 year but couldn't understand yet what to do. I am a long term investor, but after passing one year, I only have 2k profit on 350k investment. I am holding big names, What should I do? What to keep, when to purchase new or sell the down stocks? From where I can study the basics, any authentic and useful plateform? As in general browsing or youtube, it's very confusing to search the exact and useful inforamtion.
