I have always been able to purchase shares within a few months of a SPP/Raising at a lower price. (TGR, MCP, HPP, FWD, ORI, HUM in the past year or so for me). I usually look for companies who have recently done a raising and wait for the fall.
Typically If I am already invested I sell out when a SPP is announced and then reinvest later or I do not take up the SPP and average down later.
Select harvests recently did a capital raising at $5.20 and shot up as soon as it was announced - but after 3 months its back to below the raising price. I have a gut feeling that usually the more speculative companies tend to go up with a raising as it makes them more viable?
