Quote from Il Principe:
Everything has changed. Every nook and cranny of this gigantic English Muffin that we call Trading has been arb'd, what-if'd, stat-mined, spread, re-packaged and regurgitated. There's nothing left to generate outsized returns. Traders have peaked as a skilled group. So, bump the leverage; more dollar power for all. Just wait until some mega-watt vol rips into the market, boy howdy.
Do you know that some prominent British scholar said in early 1900 that there was nothing else left to invent.
This argument has been used 20 years ago and will be used 20 years later. There are tons of opportunities in the markets.
