There are two kinds of players. There are buy and hold investors and traders. Many on this board are of the buy and hold investor type. Having done their due diligence, they have decided that SLI has the potential to make them a lot of money.
The traders really don't care which way this stock goes. Their bread and butter comes from movement in SP.
Greed and fear are what amplify the movement of share prices. It's these factors that create the swings in price. At yesterday's high of $2.73 there was, to borrow a quote, irrational exuberance in the price. Today's low off $2.25 is exactly a mirror image opposite. The pendulum always swings too far in both directions.
These are market forces. For some it causes grief, frustration and concern. For others its an opportunity.
The trick is to decide in which group of players you fall. If you're the buy and hold type, just ride it out.
For those how look to the company management for news to settle price gyrations, you will be disappointed. News releases will come as the news comes in and in accordance with the myriad of rules that govern the action of public companies.
So take days like today in stride. I find it helps to look at a stock chart with a longer duration. Click on the 1m, 3m and 1yr tabs on the SLI chart and things will look much rosier.
