There is a good argument that it is better to buy in when the SP is going up rather than down. An SP going up obviously indicates an upward trend (one just doesn't know for sure for how long). You need to be able to predict a long-term upward trend. One or 2 cents at this stage will mean little in 3 to 6 months. With all the factors known about FFX (DYOR) I wouldn't be expecting the SP to come down next week.
A good book to read regarding this is "How to Make Money in Stocks", by William J O'Neill.
