I think that the only effect of reducing fractions is to make prices more imprecise, specially of smaller companies. For example in Brazil, the game console manufacturer TecToy, has its stock floating between 2 and 4 cents. Seriously, 2 and 4 cents is a HUUUUUGE range, and neither is accurate to measure the company value. But if you could value it in 0.0038215 probably it would be much better and with smoother changes.
