Several companies I have shares in have recently undertaken capital raising through share placements and each time it has been at a substantial discount to the current market price. This got me thinking as to if there are limitations on the investors/institutions when it comes to selling?

For example: the recent MHL placement SP was 2.6c and the placement was at 1.4c. If at the time the issued shares are listed on the ASX, the SP is greater than 1.4c, then are these investors able to sell immediately? I suspect the answer is yes.
