Schwab called me about an "options overlay strategy"

So I have an account at Schwab and they just called me about adding an options overlay strategy to my portfolio. Is this a good idea?

I guess that means I'd sell some calls on the assets I have in my account? So I'd get the income if the market didn't hit the strike. But if it did, I'd lose the upside and also have to pay the capital gains on the assets, since I'd have to sell them?

Is that about the size of it?

UPDATE: So I called the guy who called me back (after verifying it was a legit call from Schwab) and asked about the "options overlay strategy."

Schwab uses a firm called "Gratis" (I think) and they write puts on a basket of stocks. Then they pay out the premiums from selling options. Since I have a taxable, margin account, I could do this, because if the stocks drop, they buy the stocks on margin or something, then sell them right away.

I asked about what I'd lose in a market crash and they said they haven't had a down year since 2016.

Anyway, I'm not interested, but thought I'd give everyone an update, since I did ask the question.

2ND UPDATE: I asked my account rep who talked to me about this for more info. He had someone else who works for a firm called "Gratus Capital" send me some info:

"I’m writing to introduce myself and Gratus Capital / The Colony Group (we’ve recently merged firms): www.gratuscapital.com

We’ve been managing our income strategy for Schwab clients since 2016, generating a positive yield every year. A couple attributes to the strategy:

You continue to be a self-directed investor on your accounts

We manage a basket of options in your brokerage account to generate additional income on an annual basis

Five-year average yield is ~8.4%; 2024 yield ~9.4%; Since inception ~5.23%

I have attached our factsheet (through Q3, 2024) and a more detailed FAQ review of the strategy."

Anyway, I guess that's all the info I need, or anyone on reddit needs, so peace out.
