FOI reveals what was going on behind the scenes in HSE/DoH when schools reopened LAST YEAR:

🚨Transmission - occurred in schools/CCFs
🚨1,200 close contacts - not informed on time
🚨Linked cases in schools - missed by PH
🚨EY provided schools data to NPHET

Before I delve in, it is important to note we asked for all records from Feb 20-21 but were only given *heavily redacted* data, for *3 weeks* in Sept - Oct 2020.

[We only named the EY person as their signature was on the HSE HPSC PDF School Reports.]

So, here we go...

NPHET & HSE *continue* to state transmission is low in schools (even with the #Delta variant🙄).

The God of #Options #Greeks is often disregarded and has no mercy, especially on #Options #expiration day.

A #Thread on #Gamma.

The primary feature of #Options is their non-linear payout.

Most traders understand that #OptionsPricing is dependent on the price of the underlying, but the response is non-linear. #Gamma is the variable that describes this non-linearity.

Loosely, if #Delta is the speed of the #Options position, #Gamma is the acceleration.
