Around a decade ago, WisdomTree launched a line of dividend-weighted exchange-traded funds. The firm's AUM has grown to about $40 billion over the past 10 years. WisdomTree has also significantly benefited from having a lineup of currency-hedged equity ETFs, which now have around $20 billion in assets. The WisdomTree Europe Hedged Equity Fund and WisdomTree Japan Hedged Equity Fund are the firm's two biggest strategies.
