Gavin Filmore, CEO of Tidal Financial Group, said the expansion of the exchange-traded fund industry is only in its early stages.

This growth indicates a fundamental shift in how investors access markets. As ETFs increasingly replace traditional stock picking or mutual funds, the structure of global liquidity and asset management evolves.

Speaking on CNBC's "Halftime Report" with Seema Mody, Filmore said the financial products are proliferating rapidly. He said the market is currently growing faster than the stocks it covers [1]. According to data discussed during the segment, the number of ETFs now exceeds the number of stocks by roughly 1,000 [2].

Filmore said that the expansion of the ETF industry is just the beginning [1]. He said this trajectory is due to continued asset inflows, which suggest there is no immediate reason for a slowdown in growth [1].

The discussion included insights from Tim Urbanowicz, the chief investment strategist at Goldman Sachs Asset Management [1]. The conversation centered on the explosive nature of the industry and the mechanisms driving the surge in new fund launches.

Industry analysts monitor these trends to determine if the market is becoming oversaturated or if there is still room for niche thematic funds. Filmore's assessment suggests that the appetite for these vehicles remains strong, regardless of the existing volume of options available to traders.

The expansion of the ETF industry is just the beginning.

The fact that ETFs now outnumber individual stocks signals a transition toward 'wrapper-based' investing. This trend suggests that investors are prioritizing diversified, low-cost access to themes and sectors over the selection of individual companies, potentially increasing the influence of passive indexing over active price discovery in the equity markets.
