Sounds like you are quoting Cramer. Its not that easy - Jim Cramer is just trying to push his own agenda which is total BS and he should be put in jail for manipulating the way he does.
Quote from riskymove:
The SKF is at times responsible for 20 to 30% of the underlying stocks trading volume for the day because it has to clean up the books on the swaps by the close. Therefore, big money can game the move because they know what the managers managing the moves of the SKF (and UYG and others) have to be by the end of the day. They are adding massive volatility to the financial sector which is at the root of our issues. The SKF isn't so much a problem in normal times, but these aren't normal - and the moves it is causing in the underlying stocks are pissing the big money off. Which is why they very well may be banned.
SKF are totally daytrading instruments though most aren't aware of it. If there were you'd never hold the instrument overnight because the only thing it is designed to do it to track intraday performance x2. This too, is also fine most of the time. But I think it's really starting to wear some big money out, and the big money has the connections to do what it wants.
