According to the T. Rowe Price web site, Capital Appreciation currently has $10,106.40 million in assets. That makes it one of TRP's largest funds. Year to date it's in the top quintile for its class. Its expense ratio has fallen over the last year. It'll take more than one mediocre year for make me bail on PRWCX.
