Bottom line

HEI Technical Analysis Summary

HEI (HEICO Corporation) technical analysis shows a strong uptrend that has carried the stock near its 52-week high. On the daily chart, price at 366.80 trades above SMA20 (350.93), SMA50 (343.23), and SMA200 (318.64), with RSI14 at 63.80 and a positively aligned MACD (6.25 above the signal line at 4.99, histogram at 1.26). The daily series sits at 95.96% of its 52-week range, just below the 52-week high of 371.46. On the weekly chart, price at 356.36 remains well above the long-term SMA200 (236.82), with weekly RSI at 60.85 and a positive MACD histogram at 5.13. Immediate resistance is the 60-day high at 371.46, while support rests at SMA20 (350.93), SMA50 (343.23), and the 20-day low (334.75). As a diversified aerospace and defense supplier, HEI benefits from commercial aviation aftermarket demand and defense spending, though the premium valuation relative to historical multiples warrants attention.

Daily (August 5, 2026)

Trend
Bullish. Price at 366.80 is above SMA20 (350.93, +4.52%), SMA50 (343.23, +6.87%), and SMA200 (318.64, +15.12%). The moving averages are aligned in rising order, with SMA20 above SMA50 and both above the steadily climbing SMA200, confirming a well-established uptrend.
Momentum
Bullish. RSI14 at 63.80 is above the 50 midline, indicating bullish momentum without approaching the overbought threshold near 70. The MACD line at 6.25 is above the signal line at 4.99 with a positive histogram at 1.26, supporting the continuation of the uptrend.
Volatility
Moderate. ATR14 at 9.97 (2.72% of price) suggests an average daily move of about 2.7%. Bollinger Bands (332.79 to 369.07) show price trading near the upper band, consistent with the strong trend. Band width is moderate, indicating normal volatility conditions.
Volume
Below average. Latest volume of 348,500 is 81.1% of the 20-period average (429,600), indicating lighter participation after the recent push toward the 52-week high.

Assessment

The daily chart presents a healthy bullish picture. HEI has held above all major moving averages, with the SMA200 providing a long-term support foundation well below price. RSI in the low 60s leaves room for further upside before overbought conditions, and the MACD alignment is positive without signs of exhaustion. Volume has been below average during the latest pullback, which limits confirmation of the advance but does not contradict the trend. The 52-week position at 95.96% shows the stock near the top of its annual range at 371.46, so a break to a new high would extend an already strong structure.

Weekly (July 27, 2026 week)

Trend
Mixed but structurally bullish. Price at 356.36 is above SMA20 (313.47) and SMA50 (317.96), but the SMA20 remains slightly below the SMA50 after the sharp rally from the April lows. The SMA200 at 236.82 is far below price, so the long-term uptrend is intact even though the short-term moving average alignment is still rebuilding.
Momentum
Bullish. RSI14 at 60.85 is above the 50 midline, reflecting solid intermediate-term momentum. The MACD line at 12.41 is above the signal line at 7.28 with a positive histogram at 5.13, confirming that bullish momentum is sustained at the weekly level.
Volatility
Elevated. ATR14 at 21.92 (6.15% of price) reflects wide weekly ranges, consistent with the powerful move of the past few months. Bollinger Bands (245.97 to 380.97) are wide, with price in the upper half, in line with the uptrend.
Volume
Below average. Weekly volume of 2,240,500 is 76.4% of the 20-week average (2,931,190), indicating that participation has lightened during the recent advance.

Assessment

The weekly chart confirms a strong multi-year uptrend. HEI is well above all major weekly moving averages, with a 252-period return of +164.35% and a 52-week position of 88.44%. Weekly RSI at 60.85 is healthy and has room before overbought levels. The positive MACD histogram at 5.13 shows momentum is still expanding. The main nuance is that the SMA20 has not yet crossed back above the SMA50 after the acceleration from late April, which typically resolves as consolidation continues. The weekly structure supports a bullish outlook while price consolidates near the upper end of its range.
