Not an expert, may be put the 401K in GPIX, GPIQ, SCHD, PBDC and CEFS. May be some part of it IWY/SCHG to leave room for growth.

I think for a Roth most folks would likely say JEPQ or GPIQ since they are mostly ordinary income and taxed as that, but SPYI/QQQI is more tax efficient so that would make okay sense in a taxable account. You can contribute weekly, bi-weekly or monthly or as often as you'd like. I invest in SPYI, QQQI, JEPQ and GPIQ along with some weekly payers in my taxable because there is no limit to how much I can put in and I don't need to wait until I am like 60 to take it out.

What's your guess on what QQQI or GPIQ's average return will be when it's been around for 5 years? 10 years?

Swap JEPQ for GPIQ or QQQI and those are solid options.

Its pretty good GPIQ is better. It yields less though.

SCHD is old news, move on from it. Try SPYI or QQQI or JEPQ or GPIQ/GPIX.

I am retired. My initial strategy was dividend growers such as SCHD, DGRO, VIG, etc. spending all dividends while not touching principle. Recently I have sold some of these to experiment with covered calls (DIVO and JEPQ). Those have been winners in both growth and dividend since I bought them. Meanwhile the growers like SCHD have been a drag on my portfolio balance.
I am considering shifting all equities to higher dividend funds like GPIX, GPIQ and IDVO and reinvesting half of the (over doubled) dividends. My thinking is that with reinvested dividends, this new approach would lead to both higher income and growth over time. Thoughts?

GPIQ

I dumped mine and replaced it with SPYI but I am now favoring GPIX and GPIQ they are more NAV stable with some growth. I also like MAIN. SCHD was a dog in my income portfolio.

50% SPMO, 25% QDVO, 25% GPIQ

the two investments you have already are identical because they both invest in the S&P500 index of large US companies. there's literally no reason to own both.
if you want to diversify into other holdings I recommend looking at mid and small caps, international companies exposure.
if you want to keep it simple...you can go with something like a mix of
- SPLG 70%
- VXUS (international) 15%
- VXF (small and mid cap) 15%
as a beginner that's a solid start with 3 ETFs that gives you exposure to the majority of publicly traded stocks in the world.
if you want a more complicated mix there's lots of great ETFs you can research.
my favorite ETFs are:
- SPLG
- SCHG ( us growth companies)
- SCHD (dividend)
- XMMO (mid cap momentum)
- IMCG (mid cap growth)
- AVUV (small cap value)
- SMH (semiconductors)
- VGT (technology)
- SGOV (safe boring short term US treasury bonds)
- IBIT (bitcoin)
- JEPQ or GPIQ (covered call income nasdaq ETFs)

Also check out GPIQ it has better NAV growth.

Has anyone tried a dividend harvesting strategy on QQQI and or GPIQ or JEPQ?

Try GPIQ and GPIX. For 2024, their dividends were classified as > 90% return of capital. There are a number of closed end funds which invest in municipal bonds, no federal tax. Try PMF or NMZ. CEFs offer a higher dividend. Master Limited Partnerships (MLP) give out 100% ROC. There are several to choose from, like EPD ET MPLX WES.

I own SPYI, QQQI, GPIX, GPIQ, and others. I’m just not “all in” on anything. I value diversification. That includes diversification of strategies, not just holdings.
