I agree with the others: at your age you're too conservative with cash and too aggressive with company stock.
My story about company stock: I was buying company stock with 30% of my maxed out 401k contribution each month, plus 10% of my salary was buying company stock in an ESPP. I also held a healthy amount of stock options. I liked how my 401k balance was growing
and wasn't paying attention to rebalancing, so after the tech run up in the late 90's my 401k was more than 50% company stock
. Then it all came tumbling down. Company stock lost >95% in a couple of months. It wasn't pretty.
Fortunately I kept my job (transferred to a spinoff company as the parent company imploded) and eventually recovered. Two of my co-workers were not so lucky. Both of them held 100% of their 401k in company stock. According to rumors they both had 7 figure balances that dropped to 5 figures. One of them was laid off after the crash, so he lost 95% of his 401k and 100% of his salary. Several years later he still didn't have a job. The other kept his job but never recovered.
You may be "expecting" 3% appreciation and 10% yield. Well, I was expecting my company stock to continue its high growth and dividend yields. As they say, past performance does not guarantee future results.
