Hi Pascal,

I'm wondering how you keep track of the inevitable ticker changes within the 96 sectors comprising the 20DMF sectors/stocks population. Do you modify the set manually every so often?

For example, in the past few months I notice that MEE was acquired by ANR in the Coal sector, PDE acquired by ESV in the Drillers sector, HOC replaced by HFC in the Refiners sector (Holly merged with Frontier), APWR disappeared in the Solar sector (chinese company), GRS changed to AUQ and TRE changed to TRX in the Gold sector, etc.

Regards,
