RE:When an insiders buy?1) Insiders shouldn't be buying until after the earnings are released as the numbers should be getting close to final if not there or close to there already.
2) The fact that they have said they are in negotiaions they shoudl 100% not be buying until they either confirm no transaction is taking place, or they announce and recomend the shareholders approve a certain transaction.
I believe the rules also say they shouldn't buy for 48 before after results are released or after a transaction is announced.
