Possible, but I guess rather not than yes.
I didn't even follow the ETF news. I made a bet only once last year, I was prepared for a negative outcome, but when it happened, the server was so busy, that my sell order filled when the price was at the bottom. That's why I gave up gambling, too many random factors which you cannot control.
I rather concentrate on long-term development and intervene when there is a good occasion. I try to stay in a comfortable position, so I am fine with both directions.
