According to the 13D appearing under Meade, the issuing company has 2,851,105 shares outstanding1. But Meade has only 1.3 million shares outstanding!
There is a company with 2,851,105 million shares as of its last report. It's called Tel-Instrument Electronics. Furthermore, Tel-Instrument Electronics is listed as the issuer in the 13D, even though it is filed under Meade. There is one mention of Meade in the filing, but this could be where the mistake is made. It's possible that whoever filed this used Hummingbird's Meade 13D as a template and forgot to change this final reference to Meade.
Finally, the electronic name of the file containing the filing is interesting. It's called "tik13da-121210.txt". It just so happens that the first three letters (TIK) is the stock symbol for Tel-Instrument!
Is it possible that Meade fell 30% because of a filing mistake? If so, does it rise 50% tomorrow to recover its previous level?
I sent a message to Paul Sonkin of Hummingbird asking him for clarification but have not yet heard back.
