Re: Trump -- the last 100 days

Having read some of the things he has said and written over the weekend, it is pretty bizarre that he is allowed to be left out there to spew his venom and hatred against whatever may still be OK in this country. I assume that more precise language would be frowned upon. The only good news I can see...

Re: Trump -- the last 100 days

Yes, he is obviously on board with the national total ban on abortion, to be followed by a total ban on contraception (well, with exceptions for the king). Since that’s religion for you.

Re: why we can't use linear regression to predict share prices?

At this point I may as well also apologize to the students seeking the wisdom of their elders in this thread, which has gone off the rails.

Re: why we can't use linear regression to predict share prices?

All right, on behalf of us charming and romantic Norwegian men, I apologize! Probably the closest I ever came to chatting with a supermodel was some idle banter while playing poker with Tila Tequila in a charity tournament, back in her hey day.

Re: Trump -- the last 100 days

One wonders what his rabidly evangelical base makes of this. A bit too ecumenical for them, I’d think.

Re: why we can't use linear regression to predict share prices?

To be clear, I never said it couldn’t be done, only suggesting that it’s harder than it looks. Which, by the way, may be a good line to use when chatting with a supermodel.

Re: ATM Call Option Delta N(d1)

No, sadly, people’s language is pretty sloppy on this topic. It is generally helpful to specify outright whether you are talking about ATM spot or forward. Of course, if the volatility is 20% rather than 0.8%, the difference will be a lot less significant

Re: why we can't use linear regression to predict share prices?

If with “for a short while” you mean some small fraction of a second, you may very well be right. For longer periods, you can always hope, but don’t underestimate the efficiency of markets. There are many many cases where historical times series will suggest the presence of some statistically signif...

Re: ATM Call Option Delta N(d1)

This actually comes back to your previous option pricing question. The important ATM concept in this context is wrt the forward price. In this case, you need more than a three standard deviation negative price move to overcome the drift (which may look extreme, but your vol is tiny). The N(d1) from ...

Re: Black-Scholes and Forward Price

There are at least a couple of ways to think about this. At a relatively high level of abstraction you may notice that, with everything else held constant, the forward price is an invertible function of the stock price. Thus, if you have an expression for the value of the option as a function of the...

Re: What are the proper smart shoes brands?

It’s hard to imagine a brand that is less proper, let alone smart.
