IRA Management

I currently am managing my own IRA account through Fidelity, I have around 140,000 dollars, I’m 50 yrs old. Last year I made a 14% return on my IRA, using mostly aggressive mutual funds. I am now wondering if I should be doing this myself or have a professional do it.

Here is my asset allocation

Domestic Stocks
54.75% ($76,457.31)

Foreign Stock Value Foreign Stocks
38.29% ($53,469.71)

Bond Value Bonds
0.08% ($113.32)

Short Term Value Short-term
5.67% ($7,923.06)

Unknown Value Unknown
0.00% ($1.46)

Other Value Other
1.21% ($1,694.86)

Any suggestion would be greatly appreciated.
