I think the low share price of CIM attracts a different kind of investor than NLY or AGNC. Some CIM investors are content with holding and capturing the dividend, but others are selling evertime the share price rises 3 cents, foregoing dividend for short gains in capital. Everytime share price gets righted, there is this giant sucking sound of the day traders heading to the beer store for a six pack and carton of cigarettes.
Your right there, the low share price attracts the quick buck folks however a big increase in share price is unlikely, so eventually they move on causing an up and down effect to CIM. It will eventually even out.
