Amphastar Pharmaceuticals Stock Forecast

Sell candidate since Jul 21, 2026 Gain 1.79%

The Amphastar Pharmaceuticals stock price fell by -2.16% on the last day (Friday, 31st Jul 2026) from $20.38 to $19.94. During the last trading day the stock fluctuated 3.66% from a day low at $19.67 to a day high of $20.39. The price has fallen in 7 of the last 10 days but is still up by 0.99% over the past 2 weeks. Volume has increased on the last day by 8 thousand shares but on falling prices. This may be an early warning and the risk will be increased slightly over the next couple of days. In total, 359 thousand shares were bought and sold for approximately $7.16 million.

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 Amphastar Pharmaceuticals stock with a 90% probability to be traded between $17.03 and $21.92 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.

AMPH Signals & Forecast

The Amphastar Pharmaceuticals 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 $19.69 and $19.73. A breakdown below any of these levels will issue sell signals. 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. A sell signal was issued from a pivot top point on Friday, June 26, 2026, and so far it has fallen -8.45%. Further fall is indicated until a new bottom pivot has been found. Volume rose on falling prices yesterday. This may be an early warning and the stock should be followed more closely.

Trading Expectations (AMPH) For The Upcoming Trading Day Of Monday 3rd

For the upcoming trading day on Monday, 3rd we expect Amphastar Pharmaceuticals to open at $20.00, and during the day (based on 14 day Average True Range), to move between $19.55 and $20.33, which gives a possible trading interval of +/-$0.772 (+/-3.95%) up or down from last closing price. If Amphastar Pharmaceuticals takes out the full calculated possible swing range there will be an estimated 3.95% move between the lowest and the highest trading price during the day.

Since the stock is closer to the resistance from accumulated volume at $19.96 (0.10%) than the support at $19.00 (4.71%), our systems don't find the trading risk/reward intra-day attractive and any bets should be held until the stock is closer to the support level.
