<prompt> Human: Im in my early twenties and Im in the process of developing an aggressive retirement portfolio. Morningstar put together a couple aggressive portfolios. One is for mutual funds and one is for ETFs. What are your thoughts on the holdings in the portfolios? What would you change?Mutual fund Portfolio: 20: Primecap Odyssey Growth POGRX 20 Oakmark Fund OAKMX 15: Vanguard Extended Market Index VEXAX 30: Vanguard Total International Stock Index VTIAX 7: T. Rowe Price International Discovery PRIDX 3 Metropolitan West Total Return Bond MWTRX 5: Harbor Commodity Real Return HACMXETF Portfolio: 50: Vanguard Total Stock Market Index ETF VTI 10: Vanguard Small-Cap Value ETF VBR 30: Vanguard FTSE Developed Markets ETF 5: Vanguard FTSE Emerging Markets ETF VWO 5: WisdomTree Continuous Commodity ETF GCCSource: This might be for premium members only, but you can get a free trial if you would like to see the article.edit: formatting  <response>: 5 of something is probably not messing with...doesnt really make sense to mix indexes with active managed funds because of the potential overlapif you own total market index funds you get your markets share of exposure to different asset typs...overweighting sectors or types is just guessing with additional risk and probably a bit higher fees.
