What you think about Investment hold firms?

I am looking now at Billy Giat Brands that has an interesting portfolio of companies in bavarege and food industries that are plant based.

I am wondering if investing in this investment hold company is like investing in a small ETF. In other words, if it is like investing the companies in its portfolio with reduces risks but also less gains than direct investing in the companies that are in the holding firm portfolio.

I am cogitating it because I assume plant based food and bavarege industry are still in its experimental phase for the market to adapt.
