American Funds New Perspective fund is invested entirely in stocks (approximately half in the US and half abroad). VHGEX has a similar allocation with a similar return. The Growth fund also is entirely in stocks. VPMCX or VWUAX would be similar funds at Vanguard. 2019 was a monster year for stocks. The more stocks you have the better you did.

Your Wellesley fund is approx 1/3 stocks 2/3 bonds. The Target Retirement 2040 has about 85% stocks and 15% bonds. There is no way your allocation would be keeping up with virtually any stock portfolio in the last 2-3 years. Bonds can serve as a risk hedge to stocks but when stocks are doing well they beat bonds.
