Short-term traders obsess over entry points. Long-term investors have a quieter enemy: the percentage that leaves the account every year in fees, spreads and financing charges. It looks trivial in any single year and becomes striking over two decades.
Take an illustrative $10,000 left alone for 20 years. Suppose the underlying investments grow 6% a year before costs; that figure is purely for illustration, not a forecast. With total yearly costs of 0.2%, the pot grows at 5.8% and ends near $30,883. With costs of 1.2%, it grows at 4.8% and ends near $25,540. The one-point difference in costs swallows roughly $5,340, more than half of the original stake.
Nobody controls returns. Everybody can see, and usually cut, costs.
That is why our trading fees guide matters as much as any chart pattern, and why we explain spreads and financing before we explain strategies.
