The 1/6/15 transactions were stock awards to the insiders. 1/16 was too close to earnings release for any insider purchase/sales transactions outside of 10b5-1 plans. In each quarter there're at best ~7 weeks in the "open window" period for open-market, non-10b5 insider transactions, starting shortly after earnings release through 1-2 weeks before quarter end.
4Q/FY12 earnings released on 1/31/2013; 4Q/FY13 earnings released on 1/29/2014. If this pattern continues to hold, we are not going to see ER this week. More realistically next week.
So if you are looking for any insider purchases, they probably would come in early Feb. through mid/late March. From recent pattern, insiders do not seem interested in buying at $17 or beyond. Thus, if stock got a significant boost from ER to that level or beyond they might remain quiet. However, if they do buy at above 17, it would be a very bullish sign indicating accelerating business momentum.
