Can an ETF go negative?
I'm curious to understand, is there a possibility that an ETF can drop into negative territory? How does this concept fit within the larger framework of finance? Are there specific ETFs that are more susceptible to this risk? And if so, what are the factors that contribute to this potential negative performance? Additionally, are there any mechanisms or strategies investors can employ to mitigate this risk? I'm eager to gain a deeper understanding of this topic and how it impacts the world of investing.
