RSI Overbought in a Strong Uptrend
A large-cap stock has rallied from ₹600 to ₹820 in four months, with higher highs and higher lows. RSI(14) on the daily chart has stayed above 70 for three weeks, peaking at 84. A trader shorts at ₹815 because RSI is overbought, placing a stop at ₹835 and a target at ₹740. The stock continues to ₹845, triggering the stop. Later, on the hourly chart, a bearish RSI divergence appears, but the daily RSI remains above 60 and price holds above the 50-day SMA at ₹790. Average volume on up days exceeds down-day volume. The trader asks why the overbought signal failed and whether divergence is enough.
1. Why is an RSI overbought reading not a sell signal in a strong uptrend?
Read the worked answer
RSI overbought means momentum is strong, not that price must fall. In a persistent uptrend RSI can stay above 70 for weeks because the indicator is bounded and saturates. The short at ₹815 with a stop at ₹835 risked only about 2.5%, but the trend structure contradicted the trade: higher highs and higher lows, price above a rising 50-day SMA at ₹790, and heavier volume on up days than down days. The stop was hit because the trend continued to ₹845. The overbought reading described strength, not reversal. Using a mean-reversion signal against a trending market is a classic mismatch.
2. How should bearish RSI divergence be used together with price structure?
Read the worked answer
Divergence is more useful when it appears at a defined resistance and is confirmed by price structure. Here the bearish divergence was on the hourly chart while the daily RSI stayed above 60 and price held the 50-day SMA. That is a short-term warning, not a daily trend reversal. A valid use would be to wait for a lower high in price at resistance, combined with divergence, and then require a break of the prior swing low. Without that price break, divergence can persist and fail repeatedly.
3. Propose a risk-managed short setup, or explain why a long-side response is preferable.
Read the worked answer
A risk-managed short would wait for a daily close below the 50-day SMA at ₹790 or below the last swing low, then short with a stop above the most recent high, for example above ₹845. Position size should be based on the stop distance, not on the RSI level. Alternatively, trail a long position using the 50-day SMA or a prior swing low; do not reverse to short just because RSI is high. If the trader insists on counter-trend shorts, reduce size and use a tight time stop, accepting that the trend has the edge.
