When to Sell a Stock: How RSI Signals It's Time to Take Profits

Most investors spend all their time thinking about what to buy. The ones who actually build wealth know that when to sell is just as important — and RSI gives you a clear signal for that too.

You bought a stock at the right time. It's up 20%, 30%, maybe more. Now what? This is where most investors freeze up — or worse, hold too long and watch the gains evaporate.

The same indicator that tells you when to buy — RSI — also tells you when the crowd is getting too excited and a pullback is likely. Here's how to use it on the exit side.

RSI works in both directions

RSI measures momentum on a scale of 0 to 100. Most people learn about the buy side — RSI below 30 means oversold, potential buying opportunity. But the scale has an upper end too.

When RSI climbs above 70, the stock has been bought aggressively — more than its recent average justifies. Euphoria is high. Momentum traders are piling in. This is typically when smart money starts taking profits.

It doesn't mean the stock will crash tomorrow. But it does mean the easy gains are behind you, and the risk/reward is no longer in your favor.

Why selling at RSI 70+ makes sense

Think about what RSI above 70 actually means: the stock has closed up on most of the last 14 trading days. The buying has been relentless. At some point, the buyers run out — and there's no one left to push the price higher.

That's when you want to already be out, not scrambling to sell.

How to use RSI for selling: practical rules

Rule 1: RSI above 70 — start watching the exit

You don't have to sell the moment RSI crosses 70. But you should be paying attention. Set a mental alert. Watch for RSI to peak and start turning downward — that's your cleaner signal.

Rule 2: RSI turning down from above 70 — act

The strongest sell signal isn't RSI at 70 — it's RSI that has been above 70 and is now declining. That inflection point (the turn from high RSI back toward neutral) is when the momentum is clearly shifting. This is the most reliable signal to exit or reduce your position.

Rule 3: RSI above 80 — don't wait for the turn

Extreme readings above 80 are rare. When they happen, the stock is in truly euphoric territory. At this level, the risk of a sharp correction is high enough that waiting for confirmation isn't worth it. Take profits.

What the market looks like right now

Here's a snapshot of current RSI readings on major stocks as of this week:

Nothing in the current market is overbought — in fact, most major stocks are neutral to oversold right now. That tells you we're in a buying environment, not a selling one. When RSI gets back to 70+ on these names, that's when you revisit your exit plan.

RSI doesn't replace your investment thesis

RSI is a timing tool, not a replacement for thinking. If you own a stock because of strong fundamentals, RSI above 70 might just mean you trim the position rather than exit completely. The signal tells you the when — your thesis tells you the how much.

The combination is powerful: buy when RSI is low and fear is high, sell (or trim) when RSI is high and greed is high. It's a systematic way to do what everyone says to do but almost nobody actually does.

The hardest part

Selling at RSI 70+ feels wrong when the stock is on a hot streak. Everyone around you is excited. The headlines are bullish. You feel like you're leaving money on the table.

That discomfort is the point. The best trades are the ones that feel uncomfortable — buying when everyone's scared, selling when everyone's greedy. RSI gives you the data to do that systematically, even when your gut says otherwise.
