what is going on with mxr, page-2

Your view is too focussed on the short term and not considering the characteristics of the stock.

MXR is a highly volatile, fairly illiquid stock where a small amount of money traded has the ability to push the share price up and down by 15%.

This has both good and bad ramifications. If something big is happening to MXR then you'll see it skyrocket due to the limited liquidity.

If it fails to deliver then you'll be hard pressed to sell your holding without significant slippage.

So, just consider this is a highly volatile stock and a daily movement of +- 15% is typical. If you can't sleep at night due to your position moving up and down so much the answer is simple. Reduce your position size until you start sleeping.

Cheers,
