I’ve been trying to build a US stock portfolio by following major market trends and sector momentum, but I’m finding it difficult to time my entries. Every time a specific sector gets hot, I struggle to decide whether to buy a specialized ETF to capture the whole movement or try to find the single best-performing stock within that group. I often end up hesitation-buying after the rally has already started. How do you evaluate whether a trending US sector is safer to play through an ETF or through its top-weighted individual stocks? #MyStocksQuestion
