What Is RSI, and How Do You Use It on NEPSE Stocks?

RSI, the Relative Strength Index, is one of the first indicators most NEPSE investors meet — and one of the most misused. This guide explains what RSI measures, how to read it on a Nepali stock, and the traps that catch beginners.

What RSI actually measures

RSI is a momentum oscillator that compares the size of recent gains to the size of recent losses, and expresses it on a scale from 0 to 100. It answers a simple question: over the last N days, has buying pressure or selling pressure dominated, and how strongly? The standard setting is 14 periods, calculated with Wilder's smoothing — the same default NepseIQ uses on its charts.

• Above 70 — conventionally "overbought": price has risen quickly and momentum is stretched.
• Below 30 — conventionally "oversold": price has fallen quickly and momentum is stretched the other way.
• Around 50 — momentum is roughly balanced.

The mistake almost everyone makes

"Overbought" does not mean "sell now," and "oversold" does not mean "buy now." A strong stock in an uptrend can stay above 70 for weeks while it keeps climbing; a falling stock can sit below 30 for a long time while it keeps sinking. RSI tells you momentum is stretched — it does not tell you the exact moment it will reverse.

Used well, RSI is a context tool: it flags when a move may be getting tired, which you then confirm with price action, support/resistance, and volume — never in isolation.

Reading RSI on a NEPSE stock, step by step

1. Establish the trend first. In a clear uptrend, treat RSI dips toward 40–50 as possible pullback entries rather than waiting for a reading below 30 that may never come.
2. In a range-bound stock (very common in NEPSE), the classic 30/70 bounce logic works better: oversold near support, overbought near resistance.
3. Confirm with volume. An oversold RSI that turns up on rising volume is more convincing than one on thin, drifting trade.

RSI divergence — the more useful signal

Divergence is where RSI earns its keep. It happens when price and RSI disagree:

• Bearish divergence: price makes a higher high, but RSI makes a lower high. The new price high came with weaker momentum — a warning the rally may be tiring.
• Bullish divergence: price makes a lower low, but RSI makes a higher low. Selling is losing steam even as price dips — a hint a bounce may be near.

Divergence is a heads-up, not a trigger. Wait for price itself to confirm (a break of a short-term level) before acting.

A realistic NEPSE example

Say a hydropower stock runs up 25% in two weeks and RSI pushes to 82. A beginner sees "overbought" and short-sells the idea in their head. But NEPSE doesn't allow short selling, and the stock keeps grinding higher for another week because demand is genuine. The RSI reading was correct — momentum was stretched — but "stretched" and "about to reverse" are different things. The disciplined reading is: tighten your risk, watch for a lower-high in RSI (divergence) plus a break of the rising trendline, then consider trimming.

Sensible defaults

• Stick with the 14-period setting until you have a reason not to; shorter periods (e.g. 7) are noisier, longer periods (e.g. 21) are slower.
• Combine RSI with at least one non-momentum tool — a moving average for trend, or support/resistance for location.
• Let price confirm the indicator, not the other way around.

RSI is a momentum gauge, not a buy/sell button. On NEPSE — a market that trends hard and lacks short selling — use RSI to judge whether a move is stretched, then wait for price to agree before you act.
