The Director of Research at WisdomTree (WSDT.PK) is doing a Q&A session next week at SeekingAlpha, a website I contribute content to. If you have any questions about WisdomTree ETFs (but not their stock), please send me an email through our contact form and I will pass them on to the Editor-in-Chief at SeekingAlpha.
Update: SeekingAlpha has informed me that visitors can leave questions directly for Luciano Siracusano, Director of Research at WisdomTree Asset Management here.
