My views for what they're worth: the institutional investors will not spend much time on such a small cap. A quick (aka lazy) glance suggests a company with difficulties in a declining overall market. Abu's profit and yield is good but the II's just can't buy enough to make any difference to their overall portfolios. II's are just as lazy as the rest of us so why do your homework on something that won't make a lot of difference to your job - do the work on something larger.
Now, most II's are pretty useless (if they were really good why would they continue to invest with other people's money...? Discuss!). So there's potentially real money to be made here by those who are prepared to our homework and buy-in before others. We just to have to wait until one of the II's wakes up - of course the Deltron acquisition will boost market cap significantly and helps the alarm call. Alternatively it all goes pear shaped - that's the fun of diddy-cap stocks.
I like this way of investing - take a look at AXD or GFRD - similar stories now well on the move, possibly mostly over (sorry). MRX might be worth looking at - recently beaten up on energy prices, Rover, and high street wories but they do the niche metal bashing that is difficult for the Far East to compete with and have a solid management that belives in (almost) no debt, paying dividends and cash flow. I have holdings in all four. Let me know if you find any more...
