I'm not exaclty sure myself- having just started studying the point and figure charts myself over the last couple months.
But what I understand it is that once the stock price falls three full units below the top X on the chart, it should kick back into the "O" column, and head down. That was achieved yesteday, although it may be three full units plus the top unit itself, or four units below the top. The last couple of reversals it showed a third of the way to the top, plus three units. This time it may be a little different, because of the extreme distance it climbed from August to now (18 units). Remember, time is not a unit counted in P&F charts, only direction and height.
If I understand correctly what should show up, then the reverse "O" will appear if the "S" fund closes below 620 or so, and it will show up with four "O"s when it appears.
That would be the signal that there is much more downside ahead, as it will not reverse again until it moves downward half the distance, or upward above the current peak. If it moves downward, then it's going to be a long way down. If, on the other hand, the next movement is upward, then just the four "O"s will be all that is left.
If it DOES reverse and start showing "O's, then the floor for a reverse of the reversal (to get back to an "X",) would be at or below either the 580 or 590 level, I'm not sure exactly how it works out. I do know that it will represent a substaintial pullback, and will be a good buy signal at the other end when it shifts back to the "X" mode.
Unfortunately, I was out of the office Friday morning, and I find myself 50% in "S:" and 50% in "I" at the moment.
Win a few, loose a few. It's all in the long race, not the daily heats.
Good thing I have 12 to 14 years till retirement.
