"Someone who can sell at the top & then buy them back at there year low either is very lucky or has a crystal ball. In all my years trading shares i have never seen this done, or know anyone so lucky. I find buying shares easy, selling is harder. Just my thoughts."

The trick is to set targets and, for me, to sell only after sizable hikes in the sp, particularly after you are in a position of profit. The gap up, never to return to lower levels, is as common as hens teeth therefore, with patience, even if the sp goes up after you sell, it virtually always comes back down and retraces. For instance, if NOT goes to $10 by Wed. this week, what are the odds that NOT won't dip back down to $8, considering that it has never been that high before? You might have to wait, but look at NOT's history. So if you sold 10000 shares at $10 and bought back in at $9 because you were trying not to be too greedy, which is a safe thing to do, you would buy back an extra 1111 shares. The money isn't an issue at this point being that it is only about a thousand dollars. What is significant is what those 1111 shares will be worth when NOT is $50 a share, or how many shares you will have if you keep repeating the process. Not being greedy and being a consummate practitioner of patience is of utmost importance. .... or with NOT you can just leave it all, go on an extended vacation and come back to more money than you had when you left. It's a matter of personal investor/trader preference.
