Another baloney in corporate action is Rights Issue.
Rights issue can come in differnt variation - rights share, rights warrant or both.
Rights are usually issued at a discount to market price but I have seen cases
where they were not.
I like to use Dayen Environment to explain why I say rights issue is yet another
baloney. On 19 April, Dayen announced a 1 warrant for 2 shares rights issue. The
rights subcription price is $0.02. The warrant exercise price is $0.18. This means
shareholders can effectly pick up one more share at $0.20 for every two shares
they already own.
Today is ex-date. Dayen close at $0.51 yesterday. Based on calculation, each
Dayen share is worth $0.407 upon the rights. This is calculated as such:-
($0.51 + $0.51 + $0.20)/3 = $0.406666.
As usual, and as you can expect, the market adjust the price down. Unfortunately,
in this case the market is trading below $0.407. It is currently trading at $0.37
after opening at $0.36. The general market is weak today so maybe there is some
overshoot on the downside or maybe the market adjust more or maybe both, no
one can be sure exactly.
Now if shareholders did not exercise their rights then they suffer. If they want to
hold on to their shares and not suffer a drop in value then they must fork out
money (for the rights). So when looked at this way, rights are a demand for
money (pay or else you lose). Luckily, shareholders have an option - don't pay
and sell the shares before ex-date. Which brings me to an interesting observation.
It doesn't always happen like this extreme example. See chart below.
The rights issue was announced on 19April. I won't be surprise if prices come all
the way back down. Afterall, the bulge is very artificial.

By the way Analyst's DataServer users can update their Dayen data for the rights issue. The adjusted history is already uploaded.
