in general the blue chip reits like CMT/CCT/Areit are already super big... so they seldom have rights issue...last one was during GFC if I not mistaken (a decade ago)
small cap/mid cap reits more often will have rights issue/placement as manager want to grow the asset size of the fund... maybe every 3 years like that you still the manager ask for money once, is not uncommon
of my 3 mid cap picks
FCT - gearing below 30%... so manager can use debt first... no worries of rights issue
MCT - this year did rights issue so unlikely to see rights issue in 2017/2018... maybe 2019 may see rights
SUN - they do not have a habit of rights, but often they like to do placements only... so entry of this counter is very important... if u go in too high and they keep doing placement at below your entry price, u lugi.....
I enter at near/below STC(straits trading corp) price, so I feel comfortable at that level
