Re: Indian Economy News & Discussion - Nov 27 2017

Theory doesn't say it is not possible. After all it is a fact that currently at least future prices are lower than spot. It would merely say it is an aberration. Backwardation is the usual norm because of convenience yield (google it up /youtube it up, and why it is so or just open any standard tex...

The 10 Year yields went UP by roughly 140 bps (1.4%) between roughly June-July 17 to Feb end 18. This was driven by huge supply of paper (ie govt borrowing) , along with global yields hardening.

Canard is a done deal. Not a may be. That enables them now to increase length much beyond previously decided 0.5m. I hope they pluck that fruit. BTW, canard may add some drag but it also takes out some elsewhere, in effect reducing total drag. A well designed canard config has lesser trim drag than...

I still hope they extend Mk2 to 15m. If they think moving MLG out is too much work, that can be omitted. But I think lengthening significantly is absolutely a must given canard. The Canard may NOT needed at all. There is a better way than canard for the fuselage plug which adds weight in front of t...
