$SINGAPORE EXCHANGE LIMITED(S68.SI)$ SGX was one of my favourite stock which I track and own. Good dividend yield and good capital gain. Was high of >$11 last year, and falls to $9. Now about $9.6So is it time to add more to my portfolio?Singapore Exchange Limited, or SGX, is Singapore’s sole stock exchange operator.The group operates a platform for the buying and selling of securities such as shares, bonds and derivatives.The bourse operator has announced promising initiatives to grow its business over time.Some of these include the launch of the world’s first ESG REIT derivatives last year to meet rising demand from investors for the inclusion of ESG considerations into their portfolios.SGX is also allowing bond issuers in Asia Pacific to showcase their green, social and sustainability bonds to global investors by partnering with Nasdaq.The group also signed a partnership with Platts, a unit of S&P Global Inc to provide commodities data and content.Also we start to see SPAC listing lately through SGX’s SPAC framework which give companies an alternative capital fund raising route with greater certainty on price and execution. SGX wantes the SPAC process to result in good target companies listed on SGX, providing investors with more choice and opportunities. To achieve this, SGX will have to focus on the sponsors’ quality and track record. They have also introduced requirements that increase sponsors’ skin in the game and their alignment with shareholders’ interest. It’s encouraging to note that SGX has laid out a comprehensive plan for its revenue to grow by high single-digits in the medium term.Fundamentally, it is still very strong. And really i am not too concern with the market situation now, as in long term, SGX should do well.
