From the discussion:
The situation at the close:
NUE | Strike | Call Bid | Extrinsic | Put Bid | Extrinsic | Extr Diff |
$56.86 | $56.50 | $0.69 | $0.33 | $0.65 | $0.65 | $0.32 |
$56.86 | $57.00 | $0.46 | $0.46 | $0.92 | $0.78 | $0.32 |
But, bottom line -- if the CC and CSP had been written at the close, the outcome as of the ex-dividend date would have been:
- $57 CC: -$56.86 + $0.46 + $0.3775 + $57 = $0.9775
- $57 CSP: $0.92
- $56.50 CC: -$56.86 + $0.69 + $0.3775 + $56.50 = $0.7075
- $56.50 CSP: $0.65
The $0.06 difference between the two is due to that $0.32 variance yesterday. That is, the CSP's only collected $0.32 of the $0.3775 dividend.
But given the $0.32 variance had to be corrected overnight, doesn't that suggest some type of advantage could be exploited? What about a "Dividend Champion" that pays a dividend over $1, such as MMM?
