tract to West Coast Machinery was not material:
Without addressing the plaintiff’s business acumen with respect to the Aseco purchase, in light of all the information available to them through published material, Pike’s investigation about the status of the M-149 government contract before September 13, 1968, the public statements of the failure to be awarded the contract made at the annual stockholders’ meeting and the protests, plus the disapproval by Kleiner of the investment, the fact that Aseco had finally lost the M — 149 government contract on September 13, 1968, neither would or might have affected the action of a reasonable person in the plaintiff’s position.
Chelsea Associates v. Rapanos, 376 F.Supp. 929, 941 (E.D.Mich.1974).
It is the foregoing finding which forms the principal basis for attack by appellants, since, they argue, if disclosure of the award to West Coast Machinery was material enough to induce Rapanos to sell his stock, it was equally material to a decision of the Chelsea Associates in buying the stock. Thus, it is argued, the district court’s determination to the contrary cannot stand.
This circuit in Arber v. Essex Wire Corp., 490 F. 2d 414 (6th Cir. 1974), cert. denied, 419 U.S. 830, 95 S.Ct. 53, 42 L.Ed.2d 56 (1974), adopted the objective test of materiality in 10b-5 actions as stated by the Second Circuit in SEC v. Texas Gulf Sulphur Co., 401 F. 2d 833 (2nd Cir. 1968), cert. denied, 404 U.S. 1005, 92 S.Ct. 561, 30 L.Ed.2d 558 (1971), a test based upon whether a reasonable man would have attached importance to the undisclosed facts in determining his choice of action in a particular transaction. Arber v. Essex Wire Corp., supra, at 418; Texas Gulf Sulphur, supra, at 849.
We agree with appellant that the importance a defendant insider attaches to information in deciding whether to purchase or sell stock is highly persuasive evidence of materiality. SEC v. Shapiro, 494 F.2d 1301 (2nd Cir. 1974). However, we do not understand such evidence to be conclusive. The question is whether the district court’s finding of non-materiality can be said to be clearly erroneous. Radiation Dynamics, Inc. v. Goldmuntz, 464 F.2d 876, 888 (2nd Cir. 1972); Stier v. Smith, 473 F.2d 1205, 1208 n. 9 (5th Cir. 1973).
When Rapanos’ decision to sell his stock is considered in the light of all of the circumstances which existed at the time, the district court’s finding of non-materiality comes into clearer perspective. Rapanos’ knowledge that the contract had finally been awarded to West Coast Machinery was not, as urged by appellant, knowledge of the “loss” of the contract for it had never been Aseco’s to lose. The contract had already been awarded to a competitor; this fact was known by the investors. There was no objective evidence that had Arrow-Tech been disqualified, the contract would have been awarded to Aseco rather than to the second-lowest bidder, West Coast. Also, inherent in a job shop operation is the reasonable expectation that losses of contracts frequently occur. Hill himself admitted there was no guarantee Aseco would obtain another government contract. Finally, the evidence strongly suggests that what prompted Rapanos to sell was his recognition, from reviews of the stock transfer sheets, that he was in the process of losing control of the company. As the district court opinion points out:
“Rapanos knew of Pike’s interest in getting control of Aseco and knew of the steady purchases of Aseco stock by Hinton-Jones for the west coast shareholders until the holdings of that group by the end of May, 1968, were approximately as large as the Rapanos family. He had reviewed subsequent monthly transfer sheets and these showed additional transfers to the west coast in June, July and August, 1968, which indicated that west coast shareholders may have more shares than the Rapanos family holdings, and
