A naked call is far too risky in my opinion and I don’t do iron condors either. 100 shares being a big size of the portfolio depends on the amount of capital you have and which stocks you trade options for. There are stocks that trade at around $10 and have options available for them. For instance, FLNT is a little under $4/share and you can trade options for that stock, so it would only take $400 to get started. AMZN on the other hand would require over $300k just to do a single covered call.
