Favourite valuation Techniques

i recall reading that having 15 positions capture nearly 70 to 90% of market risk!

anyhow it does make sense to diversify fully as a manager since you dont want to be blamed for your stock picking while at the same time claiming to be a great stock picker. but dont expect your specific picks to have a large impact on your portfolio or outperform meaningfully esp net of fees.

I like to use a DCF to test the current stock price. For example, what assumptions do I have to make to spit out the current price. Are these assumptions reasonable, aggressive or conservative and what does that tell me about the current price?

A LBO model can be fun for small cap stocks and obviously useful for privately held companies.
