Apple stock ended June at $185.11, up 9.4% year to date and in bull market territory at 23.2% above its 2018 low of $150.24 set on Feb. 9. The stock is above its 50-day and 200-day simple moving averages of $184.23 and $172.66, respectively. The three horizontal lines on the chart from top to bottom are my weekly risky level of $191.59, my semiannual pivot at $181.72 and my annual pivot of $176.57, which was a magnet between March 12 and June 25.

The weekly chart for Apple

The weekly chart for Apple ended June positive but overbought, with the stock ending June above its five-week modified moving average of $184.95. The stock is well above its 200-week simple moving average, which is the "reversion to the mean" at $130.56. Note how the "reversion to the mean" was a buying opportunity during the week of July 1, 2016, when the average was $93.31. The 12 x 3 x 3 weekly slow stochastic reading ended June at 83.64, above the overbought threshold of 80.00. A close this week below $184.95 with the stochastic below 80.00 would downgrade the weekly chart to negative.

Investors should buy Apple shares on weakness to my annual pivot at $176.57 and reduce holdings on strength to my weekly risky level at $191.59. My monthly and semiannual pivots are $181.35 and $181.72, respectively, with my quarterly risky level at $210.72. (For additional reading, check out: Apple Wedge Pattern Could Signal Long-Term Top.)
