RSI in One Sentence

RSI (Relative Strength Index) is a momentum indicator that shows whether recent price action is strong, weak, or potentially stretched.

How Beginners Usually Misuse RSI

Many investors treat RSI alone as a guaranteed buy/sell signal. That often leads to bad timing, especially when fundamentals are ignored.

Safer Way to Use RSI

Use RSI as timing context, not thesis replacement. Pair it with valuation and business quality checks before making decisions.

  • RSI high can mean strong momentum, but also overextension risk.
  • RSI low can mean weakness, but not automatic rebound.
  • Use it with earnings and risk signals.

Best Use Case for Nigerian Investors

RSI is useful for entry timing around names you already understand fundamentally. It is less useful as a standalone screening method.

Final Take

RSI is a useful layer, not a full strategy. Let fundamentals decide what to buy, and let RSI help with when to buy.

Frequently Asked Questions

Does RSI above 70 always mean sell?

Can RSI below 30 guarantee a rebound?

No. Weak momentum can remain weak if business quality is poor.

Should beginners trade only with RSI?

What is the biggest RSI mistake?

Treating it as certainty instead of a probability-based context tool.
