I feel like most quarters won't necessarily give easy opportunities for insider trading, because stock prices over the course of the quarter are greatly moved by macro trends that are hard to forecast. But there are definitely some short-term events that move a stock in fairly predictable ways (an acquisition offer, an imminent recall, earnings coming in way way above or below guidance, etc). With a bit of leverage it's easy to just wait and make plenty of money off of particular events rather than maintaining a continuous insider-trading portfolio. Of course this strategy makes your trades much more suspicious too...
