Nvidia stock is the most overbought in 18 months, but that doesn't mean the rally is over
By Tomi Kilgore
The 4 previous times Nvidia's RSI peaked above 80 in the past 5 years preceded stock price pullbacks, the last one was a full-blown bear market
The monster rally in Nvidia Corp.'s stock following the semiconductor maker's stunningly bullish revenue outlook has produced the most oversold reading by one widely followed technical metric since just before the previous record close in November 2021.
But history suggests that overbought doesn't necessarily mean the rally is over. Although the four other times the stock reached overbought readings as high as they are now did precede pullbacks, three of those pullbacks were short-term in nature, and not enough to derail the longer-term uptrends.
The stock (NVDA) climbed 2.3% in afternoon trading toward a record close Friday, a day after rocketing 24.4% following the chip maker's blowout earnings report.
Meanwhile, the Relative Strength Index, known by chart watchers as RSI, rose to an 18-month high of 83.64 on Friday.
The RSI is a momentum indicator that compares the magnitude of recent gains with the magnitude of recent losses. Typically, many believe RSI readings above 70 indicate a stock is overbought, which to chart watchers means it has rallied too far and too fast compared with its historical performance and that investors are likely to cash in some gains.
Many actually interpret an overbought RSI reading as sign of strength, as the ability to become overbought suggests the charted instrument must be in a bullish trend. (Read Constance Brown's "Technical Analysis for the Trading Professional.")
Don't miss: AI stock-market surge underlines this key lesson for traders, RenMac says.
As the chart below shows, Nvidia's RSI indicator had crossed above the overbought threshold of 70 multiple times in the past five years, but with the latest foray it has passed the extreme overbought line of 80 just five times.
The first three times, an 80+ RSI led to short-term pullbacks in the stock:
The last time RSI peaked above 80 was Nov. 8, 2021 when it reached 89.17, the same day the stock closed at a then-record $308.04. The stock only pulled back 5.0% over the next seven sessions to Nov. 17, but closed at a fresh record high ($316.75) the very next day.
As the stock kept rising to a record $333.76 on Nov. 29, as investors cheered Nvidia's strength in the data-center and cloud arenas, as well as the company's opportunities to help build out the metaverse, RSI was actually trending lower to a sub-overbought reading of 69.53 that day.

That pattern, referred to as bearish technical divergence, suggests rallies are taking more and more out of the bulls, leaving them vulnerable to bear attacks.
The subsequent pullback in the stock turned into a full-blown 11-month bear market, as the price plunged 66.4% before bottoming at $112.27 on Oct. 14, 2022.
Basically, while extreme RSI readings have preceded short-term pullbacks in the past, bulls shouldn't be too concerned until RSI starts trending lower even as stock prices are rising.
It could be a while before that pattern emerges.
