Absolutely nothing. Those in the know cashed out long ago.
This was reported in 2013:
ComfortDelGro Corp's largest shareholder, the Singapore Labour Foundation, has pared down its stake in the transport giant again.
The Straits Times understands the labour body has sold 170 million of its ComfortDelGro shares for about $332 million. This is out of the 252.6 million - or close to 12 per cent share - it previously owned.
The amount raised indicates that SLF had unloaded the shares below ComfortDelGro's last transacted price of $2.18.
