As someone who read the Intelligent Investor, Security Analysis, and another Buffett book on value investing, I can't even remember now, I do recall a few things that you don't seem to even be following that are basic tenants of value investing.
First off your time frame is extremely short for a value investor. Even Buffett uses 3-5 year time frames. You said you hold for 1 year?
Also, most value investors do an extremely heavy amount of research on their holdings, are you really going to be able to research all of those positions on a consistent basis? Jim Cramer, who isn't even a value investing guy, recommends one hour per position per week. You might as well quit your job.
Third is that value investing is just dead. Computerized trading systems have killed it and the highest correlation rates among assets ever has also helped destroy it. I am not saying Buffett is dead, hell he gets to meet with board members and get his firm very nice arrangements but you are not that smart.
The bottom line is this dude, next time the market crashes everything you own in that portfolio will crash also. Then I pose the next question to you, do you stick with your value investing tenants and just keep holding for 5 years? Thats like building out a value portfolio in 2000 or 2008, it doesn't matter, the timing is what is the most important. If you have done well since 2008 its because the timing and uptrend of the market has been higher. Thats all that really matters...
