Shares in British semiconductor and software design company, Arm Holdings (ARM: NASDAQ) have rallied more than 80% in less than three months. Let's delve into the details behind this impressive surge...

Mapping the Trendline Fan

Arm’s rally from its mid-April lows can be characterised by a series of higher swing lows. Mapping these swing lows without cutting through any prices creates an ascending trendline fan. This fan is useful for several reasons:

Bullish Momentum: Each steeper line shows that buyers are stepping in more aggressively, providing a clear indication of increasing momentum.

Dynamic Support: The trendlines offer dynamic levels of support from which trend continuation traders can time buying pullbacks.

Exponential Exhaustion: Progressively steeper trendlines signal an exponential nature to the share price rally, which is rarely sustainable.

Combine With Structure and Indicators: Combining the ascending trendline fan with key horizontal levels and the RSI indicator reveals that Arm’s exponential rally took prices into overbought territory on the RSI. This coincided with prices retesting a key level of resistance, and we have subsequently seen Arm’s rally stall in recent sessions.

Identifying Key Inflection Points

On the hourly candle, recent price action has formed opposing pin-bar candles, creating two key inflection points that can be used as trigger points for short-term traders.

A break above the upper trigger point could signal a new phase of Arm’s uptrend, while a break below the lower trigger point could see a deeper retracement back towards the lower ascending trendlines.
