Evaluating Roche GS

If it weren't for the high fees charged by Swiss brokers, plus taxes, I would have sold ROG at the sell signal (at CHF 219.20 on 9 July) and bought them back at the buy signal (at CHF 213.00 on 31 July). For example, Swissquote currently charges a commission from CHF 9 to CHF 250 each for purchase and sale, depending on the amount of the transaction. Their current commission schedule is shown on the left (click to enlarge). On top of this come 0.075% federal tax and a stock market fee of CHF 0.10 per CHF 1000 transaction value.

Doing the exact calculation now, I see that a sale and repurchase would still have been worth my while, giving me a net profit of 0.7%
