Yesterday, we saw a 3+ point up move from the lows of the day ... and on no news. What could this be? Well, I'll go out on a limb and suggest that we may be bottoming out (not just Staples, but the whole market as well). I suggest that what we saw yesterday was big money funds moving back into the market. (If you managed millions of other peoples' dollars, what type of stock would you want to move the money to now?)
The big money has been pulled out of the market in recent weeks as we stumble through global uncertainty. It will, at some point, reenter the market in low risk/high growth stocks such as Staples. With the move yesterday, perhaps the tide is turning and the big money is coming back in.
I am only going on a hunch, but I shall make a prediction for you: Staples will move back to 30+ in the next 2-3 trading days. If this happens, check other bellweather stocks such as Home Depot, Microsoft, etc. to see if big money is flowing back in. (Check for high positive money flow.) If Staples and other big name growth stocks are experiencing big runups while smaller/more risky stocks are still floundering, then it may be time to mortgage the house!
I may be a little premature and yesterday may have been only a glitch. But when the turnaround happens, what I've described above will happen. Keep an eye out and good luck!
