“SkyGuy” left this comment on my post about high-priced stocks:

I disagree about low-priced stocks! $5 stocks have the highest profit potential of any stock out there. The reason is that this price level is where small companies make the jump to big companies. It’s the best part of the growth curve in terms of revenue and profit acceleration.

If Google brings in $4 bil of revenues this year, how much longer can it continue to double its revenues? Not much. OTOH, a small restaurant chain with a $4 stock with 30 stores can easily double rev’s by franchising another 30 stores.

There are 40 stocks in the $1.50 to $7 range that have outperformed Google this year.

This comment is a perfect example of what I’m talking about. He’s confusing market cap with price per share. Note that he says small companies not low-priced stocks in the second paragraph. Price per share has absolutely nothing to do with market cap! Google could do a 100-for-1 split but it would still have the same market cap and still be subject to the law of large numbers that SkyGuy rightly points out.

My point here and in the other post is that you can’t (shouldn’t) make a judgment about a stock based solely on its price per share. That in and of itself tells you nothing about the company.
