Wealth888,
I've mentioned this before. Since DLS apparently has its convertible notes trading in Singapore the short selling might be part of a delta-neutral hedging strategy.

In which case it is not malicious or part of any conspiracy against the company, just a way of scalping profits. The oil price will sort out the direction of the DLS share price in the end. If you believe we hit the bottom last Monday on oil then it should be more or less all uphill from here. If you don't you should be keeping your powder dry.
I personally don't think the oil price is pricing in enough risk. We have a war going between US backed Saudi forces and a proxy Iranian army in Yemen.

We have a caliphate of extremists occupying large swaths of Iraq and Syria and just recently unconfirmed reports out of the Israeli media that Russian forces have been deployed in Syria to support the Assad regime fighting ISIS.

The survival of the Assad regime is also important to the Iranians. All this conflict centred around the worlds major oil production centres and the oil markets behave like nothing is happening. Pile on top of that a US shale oil junk bond market funded by central bank engineered credit bubble over the last 10 years that threatens to cause a massive liquidity squeeze in the ETF derivative bond markets that could easily tip an already volatile US market over the edge a la the 2008 subprime disaster and we all think we properly know how to price oil. Low oil prices are deflationary, not good for the US, not good for the US markets at the moment. Time that people get with the program, the oil has to go up or we all go down.
