Wood said she had held discussions with Hwang about U.S. stocks and, in particular, the media sector back in 2013.

"He did provide the seed for our first four ETFs and we were very grateful to him. It was at a time where market makers were sick of seeding new strategies," she said in the CNBC interview.

Archegos Capital Management, the New York investment fund run by former Tiger Asia manager Hwang, was preparing for insolvency as banks involved in financing its trades seek to recoup some of their losses, according to a Financial Times report earlier this week.

Archegos fell apart in March when its debt-laden bets on stocks of certain media companies unraveled.

Wood said she had not spoken to Hwang recently.

"I sent him a note after I heard about the unfortunate events that we've all witnessed and I'm wishing him well," she told CNBC.
