    Oil bubble

    Forbes $30-$35 Oil Price Prediction

    Well, I am short the oil several months already. I still think at the end of the year oil will be low 40s, high 30s. On the side note, last month I was in Rome. Man, everybody is driving scooters, plus the subway trains and busses are packed! No wonder they spend several times less gasoline...

    Compounding Interest Rates

    10% historical return of the stock market is not tax/inflation adjusted. Assuming you are taxed 15-20% and transaction costs are ~.5% and the inflation is 3-4% you get real return of 5% at best. In about 28 years you’ll manage to have 4 times in real terms. Not too sexy for a life time...

    Compounding Interest Rates

    The first 100 years are the hardest because within that period you die.:D On a more serious note, getting 8% real return is admirable. The GDP of US has been growing 3-4% at the last 100 years, and I suspect the rate was similar in the past. Note that investing in an index is trading since the...

    Calculating Sharpe ratio for intraday futures strategy?

    Well it all depends how you calculate return. Normally you use return on equity so this is what you use. The risk free return is the one based on the equity not capital. Otherwise you would have 0 or negative Sharpe, even though you had 100%+ return.

    Oil bubble

    Well I don’t know about that. At 2.5$ gas if you have to buy new car are you going to buy some hybrid or a powerful SUV? People will switch to more efficient cars just like they did in the past when oil was high. They will invest in better thermal house insulation, more efficient...

    Oil bubble

    If oil remain elevated add to the list stock bubble... For most of the year stock market and oil was highly correlated. Now this relationship seems disconnected. Oil is up almost 100% from last year and this is not “Goldilocks economy” as the talking heads would like you to believe. One...

    Oil bubble

    Last week oil was up on a bearish report. Now is trading down on bullish report. However, this is the first time that I remember for the later to occur. For some time oil is not trading on the fundamentals. This is the time of mania, and anything is possible…

    Living on a boat and avoiding taxes

    Well maybe, but for someone living in California this corresponds to gross 140~150 K$. Adjusted for purchasing power this is probably equivalent to 500 K in some countries. Furthermore, as I understand you pay taxes after those 80K regular, so you would paid same amount of taxes for having an...

    Writing options for a living

    Hello, It all depends what you consider efficient. If everybody utility value was just pure monetary gain than the expected gain from option is zero. You are right of course you don’t have good indicator where the bulk of the hedging is. It all depends how you are using options. For example...

    Writing options for a living

    This may not be the case. Even under assumption future volatility is known (which it isn’t) and the assumptions the option pricing model is using are correct (distribution, etc) it may be still plenty of cases where option does not have its fair value. The reason is that not everybody...

    $100B hedge fund

    Perhaps my English is weak as I still don’t understand. Is 34% net or gross return? If is net, then his gross is 5+ 34/0.56 =60%. If is gross investors are pocketing 34*.56 – 5 = 14%.
