The 16 signals
Each signal is one indicator. Tap it to see what it measures and what it currently shows for American Tower Corporation.
EMA CrossoverPositive
For American Tower Corporation, the fast moving average is currently above the slow one. By this indicator's definition that corresponds to an uptrend, 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)Positive
Checks whether the price is above or below its 200-day moving average, a look at the long-term trend.
ADX DirectionPositive
Shows whether upward or downward moves dominate in the trend whose strength the ADX measures (+DI versus -DI).
Read in the glossaryADX Trend Strength27.3Positive
ADX stands at 27.3, 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 Intercept1.04Mixed
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)65.7Positive
RSI stands at 65.7, in the zone this indicator defines as overbought, upward moves clearly outweighed downward moves in recent days. Historically, a high RSI occurred both before consolidations and within longer phases of strength.
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+0.5%Positive
MACD stands at +0.5%, above the positive threshold, momentum over recent weeks is upward.
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+13.3%Positive
American Tower Corporation is +13.3% higher than 63 trading days ago, a positive 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 High98.3%Positive
American Tower Corporation trades at 98.3% of its 52-week high, near 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+3.6%Positive
American Tower Corporation shows an accelerating upward move at +3.6%, recent price gains 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-33.1Mixed
Williams %R stands at -33.1, a neutral position. The price is in the middle of the recent trading range, without extremes in either direction.
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 %K66.9Mixed
Stochastic %K stands at 66.9, 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

Read in the glossaryVIX Rate of Change-2.7%Mixed

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.
