When investing, is the risk/reward tradeoff linear?
If a market is efficient then risk/reward should be linear.  In simple markets like stocks and bonds, everyone thinks the same way and the risk/reward calculation is simple, so everyone can have an accurate idea of the risk/reward ratio, unless the company has serious undisclosed problems. But in other markets like derivatives and mortgage bonds, few people understand what they're buying so the risks remain hidden. Someone might think a company will do well, so they buy an derivative on that company. But no one understands risk/reward calculations on derivatives, so the risk/reward on the derivative could be way off the price on the derivative.
