If you take any finance class anywhere in the world, you are bound to come across the random-walk theory of the stock market, as well as strong, semi-strong, and weak market efficiency theory. The only way to reconcile these theories with the hunt for alpha is through differences in information - aka insider trading. The funds that consistently outperform the market are either 1 in a million lucky (how do you choose this firm as an investor? you don't), or they trade on information that others do not have access to.
Insider information is the only logical reason to invest in a hedge fund in my opinion. If you know the managers of fund X are buddies with Janet Yellen, go golfing with fortune 500 CEOs on the weekends, and vacation in Europe with French politicians. Just hope that they aren't the 1/100 that the government decides to make an example out of.
Otherwise, as most of my professors have advised, you should just invest in a portfolio of ETFs and only pick stocks for fun with money you aren't afraid to lose.
On instavest: So why would I invest with a novice hedge fund manager who has none of these connections, who is competing with the thousands of hyper-intelligent grad students our system churns out into finance every year (rather than underfunded labs and dwindling academic positions), who is just trying to get his name out there placing risky bets in a bubble of a market?
