Implication of commission-free stock trade

With no-fee stock trade, one could build a portfolio of many stocks, each with small amount but deep discount. For example, one could nibble on BRK, banks, some well-known high techs now, that are trading at various discounts. And swap them whenever other opportunities arise.

Aren’t taxes a bigger barrier than commissions for most people?

At Interactive Brokers, buying 200 shares costs $1. ($0.005 per share but minimum is $1 per trade–at 200 shares it’s a tie)

And that doesn’t vary with share price.
I paid $1 to buy one BRK/A.
I imagine a lot of people spend much more on coffee than on broker commissions.

I have traded a huge amount this year and it has added up to 0.018% of my portfolio value in half a year.
The commissions were about 2.2 times my coffee budget. (admittedly I like expensive coffee beans)

You are right. I forgot that part. Today I bought some Citigroup, and was thinking I could buy a little bit at a time, and if the opportunity passes, I will look at something else. But commission has been low for a long time, it doesn’t really matter.
