Explanation to Bollinger's Bands

Bollinger Bands was created by John Bollinger in the early 1980s, its purpose is to define price action relative to the assets highs and lows. This technical indicator is used to identify buy and sell signals and has proven very well in doing so.

Bollinger Bands consist of a set of three curves drawn in relation to securities prices. The middle band is a measure of the intermediate-term trend, usually a simple moving average, that serves as the base for the upper and lower bands. The interval between the upper and lower bands and the middle band is determined by volatility, typically the standard deviation of the same data that were used for the average. StockInvest.us uses Bollingers suggested 20 day average.

Middle Bollinger Band = 20-period simple moving average
Upper Bollinger Band = Middle Bollinger Band + 2 * 20-period standard deviation
Lower Bollinger Band = Middle Bollinger Band - 2 * 20-period standard deviation

BandWidth defines the current width of the band.
%b defines the current position within the band.

BandWidth = (Upper Bollinger Band - Lower Bollinger Band) / Middle Bollinger Band
%b = (Last - Lower Bollinger Band) / (Upper Bollinger Band - Lower Bollinger Band)

Bottlenecks in bandwidth indicate an upcoming change. Break up through the moving average line or continuous movements above the moving average line indicate a break up, and vice versa.

Spero Therapeutics Inc. stock price ended at $1.63 on Friday, after gaining 1.24%.
(Updated on May 03, 2024)

Buy candidate since May 02, 2024 Gain 1.24% PDF

The Spero Therapeutics Inc. stock price gained 1.24% on the last trading day (Friday, 3rd May 2024), rising from $1.61 to $1.63. It has now gained 3 days in a row. It will be exciting to see whether it manages to continue gaining or take a minor break for the next few days. During the last trading day the stock fluctuated 1.81% from a day low at $1.62 to a day high of $1.65. The price has risen in 7 of the last 10 days and is up by 16.43% over the past 2 weeks. Volume fell on the last day by -210 thousand shares and in total, 92 thousand shares were bought and sold for approximately $149.90 thousand. You should take into consideration that falling volume on higher prices causes divergence and may be an early warning about possible changes over the next couple of days.

The stock is moving within a very wide and horizontal trend and further movements within this trend can be expected. Given the current horizontal trend, you can expect Spero Therapeutics Inc. stock with a 90% probability to be traded between $1.43 and $1.84 at the end of this 3-month period. A break of a horizontal trend is often followed by a large increase in the volume, and stocks seldom manage to go directly from the bottom of a trend up to the top. Stocks turning up in the middle of a horizontal trend are therefore considered to be potential runners.

SPRO Signals & Forecast

The Spero Therapeutics Inc. stock holds buy signals from both short and long-term Moving Averages giving a positive forecast for the stock, but the stock has a general sell signal from the relation between the two signals where the long-term average is above the short-term average. On corrections down, there will be some support from the lines at $1.51 and $1.62. A breakdown below any of these levels will issue sell signals. A buy signal was issued from a pivot bottom point on Friday, April 19, 2024, and so far it has risen 16.43%. Further rise is indicated until a new top pivot has been found. Furthermore, there is a buy signal from the 3 month Moving Average Convergence Divergence (MACD). Some negative signals were issued as well, and these may have some influence on the near short-term development. Volume fell during the last trading day while the price increased. This causes a divergence and may be considered as an early warning, but it may also not.

Support, Risk & Stop-loss for Spero Therapeutics Inc. stock

On the downside, the stock finds support just below today's level from accumulated volume at $1.53 and $1.50.

Our recommended stop-loss: $1.58 (-3.32%) (This stock has high daily movements and this gives high risk. There is a buy signal from a pivot bottom found 10 days ago.)
