This market is chopping up many overly aggressive and overeager traders, and you can be sure that the
brokers are racking up
huge commission
fees with all of this volatility.
Plus, I should again stress longer holding periods can be a
huge advantage (not just in terms of taxes): Generally, the better the company / investment, the longer you end up holding it — and if you hold a stock for 5 - 7 yrs +, for example, the
broker fee to buy & to sell is obviously pretty irrelevant when you «spread» it over the entire period (& far cheaper than the annual / cumulative
fees you'd pay on an investment fund).
