Does anyone have strong Finance background to clear my queries ?

Hi

I am looking for someone to clear my basic concepts in Finance. Can somebody help me with the following:

1. I want to understand topics like Markowitz Theory, CAPM, Arbitrage Pricing Theory etc.,

2. Need understanding about Derivatives - Futures, Options, Forwards & Swaps with full clarity.

can someone share some resources to understand these concepts from youtube who explains well in the video? Since I am new to finance I am not sure about good videos.

Please suggest!

After watching videos if I have questions can anyone clarify?

Regards,

Jhansi
