Buy SCHG by Mar 26, 2031.

I have been putting around $1500 a month, all into SCHG since past 18 months or so. Considering my growth appetite for next 5 years, should I keep doing this or split 30%-40% with another growth fund like IWO? Also came to know about MTUM, but it may have some overlap with either of those funds depending on the market. Any suggestions are appreciated.
