The 16 signals
Each signal is one indicator. Tap it to see what it measures and what it currently shows for KLA Corporation.
EMA CrossoverCautious
For KLA Corporation, the fast moving average has crossed below the slow one. By this indicator's definition that corresponds to a downtrend, a description of past price action.
Compares a fast moving average to a slow one. When the fast is above the slow, the trend is positive. Period settings are automatically calibrated per asset class.
Read in the glossaryMA Trend Filter (200-day)Cautious
Checks whether the price is above or below its 200-day moving average, a look at the long-term trend.
ADX DirectionCautious
Shows whether upward or downward moves dominate in the trend whose strength the ADX measures (+DI versus -DI).
Read in the glossaryADX Trend Strength25.0Positive
ADX stands at 25.0, a pronounced trend, regardless of its direction.
ADX does not measure direction, only how pronounced a trend is, regardless of whether it points up or down. We use it as a filter: only above a certain value does a trend count as strong enough to give other signals more weight. Direction itself comes from the separate ADX Direction signal.
Read in the glossaryRegression Intercept0.91Positive
Fits a straight line through the closing prices of a fixed window and compares its level today with its level a few days earlier. A rising line describes an uptrend.
RSI (14)23.3Cautious
RSI stands at 23.3, in the zone this indicator defines as oversold, downward moves clearly outweighed upward moves over the last 14 trading days. In the past, counter-moves occurred more often in such zones than in neutral phases; that describes history, not the individual case.
The Relative Strength Index measures the ratio of upward to downward price movements over the last 14 trading days (Wilder smoothing) on a scale of 0 to 100. Our neutral zone is 45 to 55, tighter than the classic 30/70 band, outside of it the methodology reads the RSI as overbought or oversold.
Read in the glossaryMACD-2.4%Cautious
MACD stands at -2.4%, below the negative threshold, momentum over recent weeks is downward.
MACD measures the gap between two exponentially smoothed averages. Our periods are 12/20/9 instead of the common 12/26/9, and the signal threshold is normalized to 0.3% of the current price rather than the raw MACD value, which keeps the threshold comparable across different price levels.
Read in the glossaryRate of Change-28.4%Cautious
KLA Corporation is -28.4% lower than 63 trading days ago, a negative medium-term price change.
Rate of Change measures the percentage price change over the last 63 trading days, roughly one quarter, a medium-term window, not a short-term daily or weekly read.
Read in the glossary52-Week High48.3%Cautious
KLA Corporation trades at 48.3% of its 52-week high, well below the highest point of the last 252 trading days.
Measures how close the current price is to its highest point over the last 252 trading days, roughly one year. A value near 100% means the price is at or near its yearly high.
Read in the glossaryMomentum Oscillator-34.3%Cautious
KLA Corporation shows an accelerating downward move at -34.3%, recent price losses are larger than before.
Checks whether the recent price movement is accelerating or decelerating. Unlike Rate of Change, this indicator measures the pace of the change, not the change itself.
Read in the glossaryWilliams %R-98.7Mixed
Williams %R stands at -98.7, the price sits near the lower end of the 14-day trading range. This is the same zone classification a low RSI indicates.
Williams %R shows where the current price sits within the high-low range of the last 14 trading days. We read it as contrarian: a favorable signal only fires on a confirmed turn upward out of the oversold zone, not on any low value by itself, an extreme oversold reading alone never produces a cautious signal for us.
Read in the glossaryStochastic %K1.3Mixed
Stochastic %K stands at 1.3, currently without a confirmed crossover in either direction.
The Stochastic oscillator shows where the closing price sits within the recent trading range. A low or high value alone isn't enough for us: a signal only fires once %K and %D are both below 20 (or above 80) and %K is crossing upward (or downward), a confirmed turning point rather than a raw level.
Read in the glossaryVIX Level19.4Mixed
The VIX derives the expected fluctuation of the next 30 days from options on the S&P 500. It describes the market environment and is the same for every title.
Read in the glossaryVIX Rate of Change-2.7%Mixed
Measures how much the VIX has changed over the last trading days. A fast rise stands for quickly growing expected fluctuation. The same for every title.
Read in the glossaryHY SpreadCautious
The yield premium of high-yield bonds over government bonds, a gauge of how the credit market prices default risk. It describes the market environment and is the same for every title.
Read in the glossaryRelative Strength0.69Cautious
KLA Corporation stands at 0.69, below the reference index, price performance over the period was weaker than the reference index's.
Compares price performance over a medium-term period against a broad stock market index as a reference. A value above 1.0 means stronger performance than the reference index, below 1.0 means weaker.
