Portfolio Turnover Rate

Greetings everyone,

I have a short question on the Turnover Rate.
It seems that the calculation method is different from what I imagine.
First, what I imagine was that if I buy --let’s say 10–, then sell that same amount (=10), this will give a Turnover Rate of 100%.
However, although I almost never sell my stocks, especially relative to the size that I buy, my Turnover Rate in the Portfolio is much higher than 100%, namely around 150%.
Could anyone have the kindness to explain me how this happened?
Thank you in advance for your help!



The turnover ratio indicates the proportion of the portfolio accounted for by purchases and sales in the → reporting period. (@AndreasB )

If an inconsistent reporting period is not the explanation, please send screenshots.
