CEFS
Saba Closed-End Funds ETF
stock BATS ETF

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 like Saba CEFS (“a fund of funds” for CEFS) for broad exposure. I also like UTG. Looking to open a position eventually

CEFS, UTG, UTF...doing nicely.

ADX, PDI, UTG, UTES, CEFS, YYY.

CRF and CLM, FXED, CEFS

Those are great funds, but you may want to diversify away from covered calls. Here are some other great options to consider: PBDC, PFFA, CEFS, HIPS, CLOZ, and FSCO

I have a few different CMUTs (closed-end mutual trusts). I have owned PCEF in the past, which I liked, but found one that seems to have better performance, CEFS. PCEF and CEFS are a "fund of funds" ETF.
Others I own are BCAT, NXG, FCO, AOD, SRV, PDI, BGT, USA, BST, RCS, PDX, and MHF. Some of these are leveraged and some not. Some are bond-based, and some stock-based. Tech, financials, infrastructure, energy... good diversification and part of my 11% APY portfolio.

CEFS ETF, along with BSTZ, DNP, STEW

ADX's history makes it hard to bet against.
I own the CEFS etf. The expense ratio is high because you're paying each CEF + the one for them to actively manage & upkeep the portfolio. However I wanted CEF exposure + 8ish % dividend.
After some research I saw the ECAT was the largest holding in CEFS. Hard to beat against Blackrock, so I added some of that as well.
Then I researched sectors I wanted to invest in. THQ is a healthcare based one with a 10+ history, so I picked it up. That sector has been beat down with all the JFK fud.
NXG is an infrastructure one with a good history.
I felt like my CEF coverage was fairly diversified with those.

A 10% D&I income with minimal NAV erosion is pretty realistic, but it requires risk and diversification. You'd need some really conservative Bond ETFs and staples, combined with some covered call or other strategy for the bigger cash output. And you'd have to be willing to stay the course if a distribution dropped for a time on something (look at Zim Shipping for an example). You'd have to balance it all with an intended total raw API of around 10%, which means, for \~$500/mo, about $50,000. Now, you'd actually want a little more, because if you keep strip-mining your cash every month and leave nothing, any risk that doesn't pay off suddenly has your $500 paycheck looking like $470, $430... and then time to panic, sell something at a loss, make a mistake... $425, $390... yikes. So, bump that $50k to $60-$75k, so you can take out $500/mo. and leave some in for reinvestment.
I currently have my raw APY at 11.3%. Capital growth is pretty slow, but I have been only taking 10% of my D&I income and reinvesting the rest, spreading it across high and low risk, high and low income, products. A few are YMAX, FCO, ASGI, CEFS, VOO, MLPX, TFLO, and XLC. I maintain 64 products total.

Not more than 5% in any one holding, invest across various sectors and types of investments (REITS, CEF, MLP, Equity, Bonds, covered call etfs, etc). Some examples; JEPI, BND, BST, RLTY, CEFS, CLOZ, QQQI, FSCO, BALI, ADX, IDVO, IBIT, BTCI, BSM, MPLX, ARCC, PBDC, PFFA, etc. I like to hold RSP,SCHD, and VOO also. I don’t drip, I look at my portfolio a couple times a month and buy whatever is the best value at the moment. If nothing looks interesting I’ll park money in TLT or BND until I need it. Understand what you own, keep educating yourself constantly. Good luck on your journey
