After 2nd weekend is known, Delist is approx 2nd WE cume + (2nd WE cume- 1st WE Cume)
After 3rd weekend is know, Delist is approx 3rd WE Cume + 1/2 of (3rd WE cume - 2nd WE cume)
This is MY personal rule of thumb, not scientific, but it gets me close.
Example....CLSH2 Adjuist was 92.34
1st WE 33.5; 2nd WE 58.6....this projects to (58.6 + (58.6-33.5) ) or 58.6+25.1 or 83.7
3rd WE 713 this projects ot (71.3+ 1/2( 71.3-58.6) or 71.3+ 1/2 (12.7) or 71.3+6.3 or 77.6
Delisted at 77.23 This trended downward for all 4 weeks and the price and in my head I felt that my short was a good idea.
LORAX... adjusted to 190.94
First WE approx 70; 2nd WE Approx 122.... 122 + 52 projects to 174
3rd WE approx 158 ..... 158 + 19 projects to 177.....
Delisted at 177.41
It is very approximate...I usually do not go into decimals but use it as quick way to estimate.
