Polar Capital Technology Investment Trust - fairly solid, main holdings if I recall correctly in the likes of Apple, MS, Google, IBM, Samsung, amounting to over two-thirds. I have it on stock watch and am tempted partly because Apple is oversold and the trust's record is rather good
Biotech Growth Trust I bought last year and has done well, again mainly N American holdings (which fits one of my medium term investment strategies), management takes a slice of any outperformance of the benchmark (but good incentive, why grudge them). Buying/holding it is an act of faith in biotech, the managers, and the US economy.
Back home I am also watching Innovation Group which reports 1 Feb. Recommended as a buy by several brokers a few weeks ago.
None of these pays out a dividend.
