I have noticed with shell stocks that there are always many chances to enter as long as there is no news and the waiting for an acquisition continues.
Might not get in below 2c but i strongly believe i will get a nice safe entry price (possibly may even be in higher than today, but safe, however i reckon low 2s will happen) sooner or later. No point rushing in because shells are often a longish waiting game with fluctuations. I always look to get in at established support levels and if i can't, i move on or wait for a new safe support.
