I noticed a pattern. Let me post it Streetsmart style here:
1) The hedge funds and investment banks will load up on a speculative instrument.
2) After they do, they will feed the information to their private banks (e.g. JP Morgan Investment Bank to JP Morgan Private Bank).
3) The private banks will then recommend the trade to all their customers (in many forms - outright purchases, accumulators, structured-linked products)
4) These customers (ultra to normal high-net-worth) will load up, pushing the market further up.
5) At a certain point, the consumer bank mass affluent customers (typical sinkie-stay-condo-yaya-type) will be advised by their RMs to buy. So they load up as well.
6) At the height of the frenzy, the investment banks will sell it to all these wannabes and blur-fucks, taking profit on them (1st time).
7) The hedge funds and investment banks will then turn short, and push the market down
8) The customers at some time will panic and cut losses (because blur-fuck customers all listened to their RMs and go margin trading to leverage up)
9) The hedge funds and investment banks will buy and take profit on the customers again (2nd time).
The cycle rinse and repeat. Gold and silver right now is like that.
Cheers.
