Just want to ask you guys, is it worth to subscribe their services? It cost USD150 per year. And if anyone subscribing their services, do share your opinion/experience on this particular subject. Thanks.

These sites are mainly third party rating companies.
By subscribing to them, you could get updates and research reports from them on funds, ETFs and stocks.
One problem is that their coverage might be limited, because they are covering the global markets.

One good way to get free research reports is by using Bursa Malaysia's CBRS, which includes reports by Standard & Poors, RHB, Netresearch-Asia, OSK, SJ Securities, TA, JF Apex and Inter Pacific.
You could have access to all these reports for free.
But one word of caution though. These research houses are being paid for their coverage, so it might not be as accurate or honest

Regards.

regarding motley fool, their researches are very good, and mainly fundamental. but it cover most of US stocks. what I would suggest is that u go and search for their books, title 'motley fool investment guide' adn ' u have more than what u think u have'. I dont see them in current bookshops, but if you're lucky, you'll find them in 'pay less book' shops.
