Definitely invest all of it in MO immediately, you'll be stinkin' rich!!! Just kidding, we'll kick you off the forum if you do something that boneheaded. 
I have a lot of stock positions, and most of them are 100 shares or more, but I will always keep a significant amount in the S&P 500 index. I don't keep as much in bonds as conventional wisdom says I am supposed to, but I always have a cash position, and I am not afraid to get a little too cashy when I think my overall stock holdings are getting over valued. I've beaten the index handily the past few years, and I sleep better at night knowing when the big one comes I can go shopping and buy thousands of shares.
I hear you on the port volatility because I look at my account balances daily. For many years I didn't do that because it's not conducive to good decision making when you still have decades to let it ride. For at least the past 10 years my port's daily valuation swings exceed what I make at work in months. Occasionally MANY months. Whenever you get financial advice from others, be mindful of where they are in life. I'm not 25 or 70yrs old, and IMO I shouldn't invest like I am.
I'm typing too much as always, but bottomline is YOU have to be comfortable with your allocation strategy Life is too short to be stressing your money on a daily basis. (That's some free old guy wisdom for you right there lol)
