There are better choices.
Expense ratio is 0.3%, but assets under management are 56 billion! (that is Fidelity type assets for an actively managed mutual fund).
Till proven otherwise, that is a quasi-index fund that may make some contrarian sector bets to outperform the market over time.
If this is truly set it and forget it money, VTSMX is boring but will serve you will over time (has even better advantage in taxable account because it is so tax efficient). It owns the whole U. S. stock market, so it will lag, and possibly lag badly, when one particular sector of the stock market is doing well. However, over the long term, it is extremely aggressive in the most important way - strategic asset allocation, in that it is always over 99% stock with minimal cash position. Most actively managed funds keep 5%, possibly 10%, in cash and over time stocks >> bonds > cash. Low expense ratio (Vanguard will automatically convert you to admiral shares when you reach minimums) and low hidden costs (buying and selling costs from turning over portfolio rapidly) give the fund say a 2% average annual return tailwind vs most actively managed funds (i. e. actively managed funds, because of high expense ratio and hidden trading costs, have to beat the market by over 2% a year just to keep up). Ideal for taxable account where you would first draw down ira type accounts and leave this as growth component till late in retirement because it is very tax efficient (can almost be considered tax deferred, but you don't have to start taking money out at a given age). Still, for someone with a 20 - 30, or ideally more, time horizon, it is still a great choice in tax deferred account, if you are truly set it and forget it type.
If you have access to Vanguard Brokerage account within the IRA, LLPFX is a fund I like alot.
