    9 reasons why investors are scared

    Huh? "There's no alternative" forms the basis for reasoning in exact sciences and logic. I'm sure you understand proving by contradiction ("reductio ad absurdum") as a computer scientist. If (not A) is false then A must be true. There is no alternative. I just wanted to point out that...

    What if the US Government was run by a Hedge Fund?

    And you are assuming that random data means i.i.d. It is not necessarily the case. As for your experiment, how do you want to generate the RW's? With a bias like markets have? Then a flipping strategy where you go long/short when crossing the origin will give you positive expectancy with a...

    Hired Talent: What are the Costs and Risks?

    I don't know the specifics of your situation. You have some legal and technical protections (ex. use several brokers, have programmers work on modules and not on the whole system etc.). We do all of them here. But the most important thing is that your employee's benefits are aligned with...

    dumb question: if my friend wants me help manage his money

    Few, a handful. Most of our clients aren't my friends, fortunately. :) And also we have high minimum investment so that limits the number. Ninna
