Newbie ALERT

Hey everyone
I'm 22/23 and I soon will get some money to start building my portfolio. I want to invest 10k in my trading account and I am a little confused of about how much I can make.
Let's say I invest the whole 10k into apple stocks and the apple share goes up by 4% after a week. If I sell it then would it mean I made 4% profit????
Of course (minus tax, broker fees)

Yep, your calculations are correct also if the stock tanks 10% on disappointing iPhone sales, you'll loose 10%... My advice is do not trade if you don't have a plan...

If all act rationally, traders will stop making money. After all, the lion's part of the profit is received by the trader because of errors of other bidders.
