Natera Stock Jumps 13.69% In 3 Days As Technicals Signal Bullish Reversal

Technical Analysis of Natera (NTRA)
Natera (NTRA) concluded the most recent session with a 3.35% gain, closing at $157.04. This marked the third consecutive positive session, contributing to a significant 13.69% gain over this period. This sharp rebound follows a prior volatile downtrend, warranting a detailed multi-indicator technical assessment.
Candlestick Theory
Recent price action presents a notable bullish pattern. The session on August 7th formed a Hammer candle, characterized by a long lower shadow (low: $136.21, close: $141.08) near the established support level of approximately $135-$138 seen earlier (August 6th: $135.75 low). This signaled potential exhaustion of selling pressure. The subsequent sessions confirmed a reversal, culminating in three consecutive white candles (up days) with progressively higher highs and closes. Immediate resistance is encountered around the $165 level, corresponding to the high from August 8th. A sustained breach above this level, especially on higher volume than seen during the recent rally, would signal stronger bullish conviction. Key support lies near the $150-$152 zone (multiple daily closes/lows in July-August) and more significantly at the $138-$135 zone.
Moving Average Theory
The 50-day moving average (MA), currently estimated around $151-$152, is showing signs of flattening and potentially turning upwards after the price recently reclaimed it. The price is trading well above the longer-term 100-day MA (approx. $148-$150) and 200-day MA (approx. $144-$145), confirming an overarching long-term uptrend. The 50-day MA crossing above the 200-day MA (a Golden Cross) occurred earlier this year and remains intact, adding long-term bullish weight. The recent pullback found support near the 100-day MA before rebounding strongly. The price position relative to these averages suggests a short-term bullish trend resumption within the broader uptrend.
MACD & KDJ Indicators
The Moving Average Convergence Divergence (MACD) for NTRA is exhibiting bullish signals. Following the price plunge on August 8th, the MACD line has subsequently crossed above its signal line and is ascending towards the zero line from below, indicating building bullish momentum. The Histogram has turned positive and is expanding, reinforcing this upward momentum signal.
The KDJ indicator, however, presents a more cautious picture. After the recent surge, the %K and %D lines are nearing or entering overbought territory (typically above 80). While this doesn't preclude further gains, it suggests the current rally may be maturing and vulnerable to a short-term pullback or consolidation in the near term. The divergence in signal strength (bullish MACD momentum vs. overbought KDJ state) warrants attention.
Bollinger Bands
Bollinger Bands experienced significant expansion during the sharp price decline on August 8th, reflecting high volatility. Since then, the bands have shown signs of slight contraction as the price consolidated and then rallied. The current price is positioned near the Upper Bollinger Band ($157-$159 estimated). Trading near the upper band signals the price is statistically extended on the upside in the short term, aligning with the overbought reading suggested by the KDJ. A move inside the bands or a failure to break decisively above the upper band could signal a pause or retracement is imminent. Monitoring band width (volatility) remains crucial.
Volume-Price Relationship
Volume analysis presents a notable divergence. While the price rebounded strongly (+13.69% over 3 days), the trading volume during this rebound (Avg ~3.05M shares over 3 days) was substantially lower than the volume witnessed during the preceding sharp decline on August 8th (3.85M shares). This divergence raises a yellow flag regarding the strength and sustainability of the current rally. The lack of confirming high volume suggests participation may be lacking and increases the vulnerability of the price to a pullback. Significant resistance breaks would require notably higher volume to validate.
Relative Strength Index (RSI)
The RSI (period=14) recently dipped close to the oversold region (briefly nearing 30) during the early August sell-off. The subsequent rebound has pushed the RSI sharply higher, currently estimated to be around 58.5. This places it firmly in neutral territory. While it has moved away from oversold levels, confirming the rebound, it is not yet in overbought territory (>70). However, the rapid ascent of the RSI from oversold suggests the rally has been swift. A potential negative divergence would form if the price makes a new high (above $165) while the RSI fails to exceed its prior high from early August.
Fibonacci Retracement
Applying Fibonacci retracement to the significant swing high on August 8th ($165.09) down to the swing low on August 7th ($136.21) provides key levels. The 23.6% retracement level is around $142.20, which the price surpassed relatively easily. The 38.2% retracement level is near $148.40 – a level that coincides with the 100-day MA and acted as resistance initially before being cleared decisively on August 11th. The critical 50% retracement level sits at $150.65, recently overcome. The next significant hurdle is the 61.8% retracement level near $154.30, closely followed by the 100% retracement/resistance at $165.09. Support levels align with the Fibonacci retracements: 50% ($150.65), 38.2% ($148.40), and 23.6% ($142.20).
Conclusion
Natera's technical posture shows a strong short-term recovery within a prevailing long-term uptrend, confirmed by moving averages and Fibonacci analysis. Candlestick patterns clearly signaled the reversal near $138 support. However, confluence points highlight caution near current levels: the price sits near strong resistance ($165), the upper Bollinger Band, and a key Fibonacci level (61.8% retracement at $154.30, recently exceeded but needing confirmation). While momentum indicators like MACD are bullish, significant divergences exist: Volume is notably weaker during the rally compared to the preceding decline, and the KDJ indicator is overbought. The RSI ascent also suggests the move may be extended short-term. Probabilistically, while the trend bias is positive, further upside progress needs strong volume confirmation at resistance ($165) to be sustainable. Failure to break $165 convincingly, particularly if paired with persistent low volume or KDJ rolling over, increases the likelihood of a pullback towards support zones around $152 or $148-$150. A decisive, high-volume break above $165 would open the path towards the highs seen in May-July near $170-$173.
