Here are three ETFs I would appreciate seeing in the market:1. An expensive company ETF - there are already "value" ETFs that hold companies with low multiples. But a low multiple is often because the market is pricing in less growth. A high multiple ETF should therefore hold companies that the market is pricing in strong growth.2. A business non-discretionary ETF - there are already consumer discretionary funds, but you're far more likely to find higher quality recurring revenue in companies selling essential products and services to other companies.3. A semiconductor equipment ETF - this would invest in companies like AMAT, ASML, Cadence, KLA, Lam, Synopsys and Tokyo Electron. Exposure to the infrastructure as a whole, rather than any one end-market, should hedge a lot of risk.What do yo
