Heres a link to the online streaming of the Valuation Class by Aswath Damodaran. Aswath Damodaran is a amazing professor who has been teaching Valuation and Corporate Finance at NYU Stern for the last 26 years. He has also written numerous books on valuation. I finished watching the first lecture and I must say there was never a dull moment in the 1hour 25 min lecture. In fact, learning valuation was never more interesting.
If you want to know more about him and his class, below is the link to his blog.
