Buying defensive rated stocks

Serenity,

I just wanted to thank you for creating the stock screener. I found the Intelligent Investor last year and have read and
reread it a couple of times, but still find much of it indecipherable, but an excellent book nonetheless. For me it has been difficult understanding all of Graham's criteria, especially never having invested in stocks. It's nice to know that there exists a method of investing that is based on sound judgement and methodology, and his method resonates with me. I had been looking for a stock screener that applied Graham's criteria and hadn't found much success until I discovered your site. Your site was also very helpful in clarifying Graham's rules for me, so I thank you for that as well.

I just have a few questions:

1. Are there any good reasons to not buy a stock that meets Graham's defensive criteria?

2. As far as asset allocation goes, Graham generally recommended a 50/50 bond stock allocation. Is this still appropriate given the recent market climate or would a larger allocation of in stocks be better. I'm 30 years old and have virtually no bond holdings.

3. How do you feel about stocks that meet all of Graham's defensive criteria with the exception of $500M in fees?

Thank you for creating the screener and also for your time.

Thanks,
Learning Graham
