when will directors start buying??

Directors are prohibited from buying/selling shares within a week or two of a earnings report. Also not allowed to buy if have knowledge of sudden change to company eg. impending TO or collapse in SP due to loss of a major customer. IMD SP is about 55% of its price of early April. One director sold some shares on 20/03 for $2.91 and one bought shares on 03 May for $2.62. But vols were not significant. SP now $1.71. If 4QFY12 is anything like 3QFY12 then surely directors would be piling-in with final report due is about 6 weeks time. It does concern me we have seen so little of director's own money invested into Imdex. Some purchases would provide enormous confidence to holders that board have faith in own company's future earnings. Will report in August spring a surprise? By law directors have to warn market should early indicaters signal earnings will deviate by more than 15% from what company has implied in earlier presentations/notices. Now 09/07 and company will know the (unaudited) earnings for FY12. Let's hope things are going well with BLY and with American JV.
PS. ILU announced today 4Q earnings would be well below those of previous quarter. SP smashed down 24% in a single session!
