Sounds mostly like gibberish to me, sorry to say it.<p>> By the 90s, hedge funds were back, this time capitalising on advances in sheer computing power that permitted real-time pricing of instruments in volumes never previously possible. By introducing more and more complex derivatives and so increasing the difficulty of pricing the market, hedge funds managed to maintain this source of alpha almost until 2000.<p>There are very few funds who make a living pricing complex derivatives. I used to work in a couple of funds that traded derivatives, and quite often we had to explain to people what volatility trading was. Generally, the more complex it is, the more the market maker will charge you in spread for trading it.<p>It's also not computing power that allows you to make money trading them. A few numerical PDE solvers do not take a huge amount of computing power (or indeed data) to calculate. The people who make money off it are the ones who manage to sell a product to a client at a price the client doesn't understand. I wouldn't use "complex derivatives" as speculation vehicles ("I'm bullish/bearish -> trade") in themselves.<p>> Even as the market caught up and the potential for alpha withered for hedge funds in the early 2000s, these newly-technically-savvy funds shifted their focus to speed; driving in the era of the hyper-successful HFT firm that drew massive, riskless profits from the sheer speed at which they could capitalise on arbitrage opportunities.<p>HFT firms are not hedge funds. I'm sitting in the offices of one right this minute, writing code for a strategy. It's not something outside people can invest in. I wouldn't say the profits are riskless either, they're just not traditional risks that you list in a finance course.<p>> The winners in this market will require many of the skills that have been required before - deep market understanding, strong technical competence and grounded, balanced leadership - but they will also require a new skill; the ability to acquire, make sense of and apply these new data sets.<p>Gibberish. You need to know what you needed to know, but also to be open to new situations?<p>There's no discussion here of how various styles generate their alpha. What do macro guys do? Surely not complex derivatives and HFT? What about special situations? And activists?
