In this edition of The Motley Fool's "Ask a Fool" series, Motley Fool analysts Jason Moser and Brendan Mathews take a question from a reader who asks, "What is up with WisdomTree Investments (WT -1.34%)?"

WisdomTree Investments stock has pulled back strongly and, as Brendan explains, it's a function of slowing assets under management (AUM), weakness in emerging markets products, and fear about the sustainability of the hedged Japanese equity ETF. Those factors have created pessimism in the stock, but Jason thinks the market is too focused on the short term. Brendan agrees, and he thinks that now could be a great time for long-term investors to initiate a position in the stock.
