Is it bad practice to invest in stocks that fluctuate by single points throughout the day?
Eventually, you'll end up buying a stock at or near a high-water mark.  You might end up waiting a few years before you see your "guaranteed" $100 profit, and you now have $5K to $10K tied up in the wait.  The more frequently you trade, the faster your money gets trapped. There are two ways to avoid this problem: 1) Do it during strong bull markets.    If everything keeps going up you don't need to worry about peaks...but then why would you keep cashing out for $1 gains? 2) Accurately predict the peaks.    If you can see the future, why would you keep cashing out for $1 gains? Either way, this strategy will only make your broker happy, $8 at a time.
