We normally think if you're going to lend someone money, you should get some reward for doing this. In Europe, it's a tax!

Most people are under exposed to global assets, including foreign stocks, bonds and currencies.

Investors have to ask themselves two questions. How much can we grow our investments? And, can we afford our mistakes?

The world changes! So we're in a situation today where the only policymakers that have flexibility are central banks. But they don't have the instruments! So they've had to experiment, and the more you experiment, the more uncertainty and the higher the risk of collateral damage.

As we spend more, and as companies are pushed to invest, they say, "Hey wait a minute! There's more demand in the system. Let's invest more."

I remember when I was growing up, you would go to a bank to open a deposit, and they'd give you a toaster. A free toaster. These days, if you're a company, and you go to a bank, they could easily turn you away! They don't want your deposits anymore.

As a whole, investors should welcome attempts to safeguard the integrity of markets. You need very clear rules applied to markets.
