Apple (AAPL)

New BUY signal the week of 7.29.13 (Friday) at $462.54. My initial stop is $393.59, so my risk (R)/share is $68.95 (14.91%).

That probably seems like a very wide stop, but my Value at Risk (VaR) calculation (at a 99% confidence level) is -10.10% ($46.74), and my Worst Actual/Historical Weekly Drawdown is -19.43% ($89.87), so 14.91% ($68.95) actually sounds about right.

At least to me it does.

History (beginning in 2003):
Winning Trades: 3 | 75.0% | +$203.20/share avg.
Losing Trades: 1 | 25.0% | -$12.10/share avg.
