I cut and pasted from your cut and paste.

Why are you guys getting so bent out of shape?
I googled it.

Very good.

Black and Scholes is an options pricing model. Makes a few assumptions to arrive at a price for the option to allow suitable hedging for the underlying asset e.g. shares. You use it for Euro call options. It’s generally the accepted calculation for pricing and has proven to be accurate. Of course you can make incorrect assumptions like any business case and your pricing will be wrong. Back in the day when I worked on the trading floor in London (I wasn’t a trader I’m terrible at math) software like Muex etc utilised B&S.So it’s the accepted standard.

I’m interested in this Tabet guy as he doesn’t believe in B&S as a hedging strategy, even though it’s proven and the guys behind it given noble peace prizes. He also doesn’t use academic references to support his own papers. So as a few of you guys are supporting his theories (don’t know if they have been peer reviewed) I’m interested to understand why his Black Swan book etc is so informative

A Black Swan Event Concept is based on what happened when Early European Explorers discovered black swans in Australia. In classic philosophy the concept of a black swan had been used as an impossible anomaly. Swans were always white. A priori ideals. After that the concept had exactly the opposite meaning.
It’s all about being ready for the last war and not being ready for the next curved ball that uproots the foundations.
In relation to technologies for example you can look at what is suddenly superseded but also at what old technologies or practices may suddenly become relevant again.
Not particularly useful for assessing minor variations.

I’m sure Steve can give you a definitive summary.

Thanks Beans. It’s a little philosophical by the sounds. I’m trying to think about superseded technologies that have become relevant again. Maybe nuclear power may be one after green energy fails (not saying it will fail. Relax people)

Okay, for example….bicycle couriers were made redundant by emails. Now smart phones and Ubereats have brought them back. Old ones used to be more pro though. Vinyl Records?

I did.Still don’t understand his bent. Might read up. Although philosophy is a little abstract for me. We’ll see.

Might head up to Kirra for this swell and do a couple of laps.

Surfed it this morn.
2ft junky swell.
Few holes in the bank but that be a good thing for the everyday man to get a few when the swell arrives.

Kirra Surfriders have an open club round penciled in for Sunday, hopefully they'll get the lollies.
