Nevermind the several other issues that are still unclear, but one problem with MCX that immediately comes to mind is this:
Before the scam was exposed, MCX posted huge turnovers and brokerage gains from them. These were fraudulent and the companies chieftains greatly benefited. However, after the scam MCX is going to have to survive with a much lower turnover. This makes us wonder, does the enterprise have the leadership to restructure expenses (read: top level employees and their perks)? It may, but it is rare that an MD who once had 5 BMWs will now settle for less.
The business model is great, just like Satyam. And on similar lines we may see another corporate move in to buy out MCX from the parent. But, those are all ifs. Nothing is clear.
Moreover, MCX started quoting at around 1400 in March 2012. Then came the scam after which the revenues significantly reduced. So we do not really know at what price should MCX be valued. Who knows, it may even lose another 50% from here.
There are a lot of ifs. The business is good, low in investment and high on consistency. But, it is in a mess.
