I was just wondering while looking at some ETFs. Lets say I want to go long Technology and I find your regular ETF to do it. Holdings of that ETF would be your usual Apple, Google, Microsoft, ok makes sense. Lets say I want to go short Technology and I find an ETF to do that and inside of that ETF I would find the usual Apple, Google and Microsoft.
Now this is my question. It is understandable to have workhorses in long ETF but shouldn't short ETF have garbage in it like Twitter, GoPro etc.
