On the surface, the answer is obvious isn't it?
Who wants to buy something for $6, when you can buy it at $4?
But if you think $4 is cheaper than $6, what if I tell you that you are not necessarily right?
What if I tell you that the answer depends on what type of trader you are?
Take a look at this chart.
Imagine you are a mid-term swing trader who buys at the pivot point, and hold stocks anywhere from a few days to a few weeks.
You bought PARKSON at $6 at the pivot day 28 March 2008.
This is a wonderful timing, because it broke the downtrend line on that day, and easily exceeded $6. Any swing trader worth his salt whould have gotten approximately 5% to 10% return in a few days/weeks.
Yet, imagine if you bought PARKSON today at $4.
Of course, $4 is cheaper than $6 ...
Yet, the swing trader would probably not want to touch PARKSON at $4 today, but he is happy to buy PARKSON at $6 on 28 March 2008.
The question you have to ask yourself is which type of trader are you?
Are you happy owning PARKSON on 28 March 2008 at $6?
Or are you happy owning PARKSON today at $4?
Investing & trading are not absolute concepts.
Think about it.
