    Isn't buying dividend paying stocks for chumps?

    counter point on my 3) above: if a company generates huge revenue in surplus of investment opportunities then it make sense to return capital to shareholders, instead of hoarding cash or splashing them somewhere outside of their expertise. maybe in this case div paying is correct decision and...

    Isn't buying dividend paying stocks for chumps?

    i had the same question for years which i also posted on this forum before. i still think there's an irrational tendency for some to prefer div paying stocks. they have these illusions: 1) "they're safer" - generally true but thats because stable div paying companies are usually mature...

    Selling OTM (not deep) and buying units to hedge

    You need to buy more far OTM puts than the near term you short (in number of contracts, assume same maturity) to also profit from black swan events, otherwise it's just a spread and the far put just caps your losses. Play around with a maturity date payoff graph to see what option "combos" you...

    Making 4% a year selling deep OTM covered calls?

    Yes. Depends. Theta decay is highest for short term options. I believe one should still look for an edge, even when selling covered calls. Such as finding mispriced options or timing. Otherwise it'll just be an -EV asymmetric payout trade with the illusion of being profitable, until a home...

    How to realize buying cheap vol

    Gamma scalping (periodically resetting to delta neutral) should lower the pnl variance but with hedging costs so over-doing it could be costly. Holding to maturity is the other end of the spectrum with theoretically the highest variance and also EV. There should be a sweet point somewhere in...

    why are High Dividend stocks perceived to be superior?

    XIV and VIX futures

    Thanks quant1, your formulas led me to the below findings. Originally i thought XIV return is: N1 = N0 / (1+r) which gives the below incorrect payouts (in all cases total value always > initial. Using XIV (approximate) return: N1 = N0 - (r * N0) I get below instead. so when VIX is flat after...

    XIV and VIX futures

    Thanks sle, Maybe convexity was a wrong word choice, but what I thinking was the VIX futures can triple in value while losses from XIV is bounded by 0. So in extreme scenarios this should be profitable? Meanwhile in "normal" days the two seem to offset each other quite closely.
