Unintended Signaling, from Henrik Andersson
Some examples.
You have the insider that buys shares in their own company where there is a takeover rumor. If the stock doesn't go down it should. [If there was a real takeover under way the exec would know about it but would be legally prohibited from buying. Hence the takeover rumor is debunked by his buying].
Today I met a manager of a company who was surprised the share price didn't go up when they didn't start the buyback after the quarterly report– like they usually do. The share price didn't move up until after the orders were released to the market. [The postponement was due to an important announcement pending. The fact the company did *not* do the usual thing should have been a clue that something was up].
What other unintentional signals are there?
