Buy or Hold candidate since Nov 10, 2025 Gain 0.05%

The Glaukos Corporation stock price fell by -1.81% on the last day (Monday, 17th Nov 2025) from $90.03 to $88.40. It has now fallen 3 days in a row. During the last trading day the stock fluctuated 2.43% from a day low at $88.31 to a day high of $90.46. The price has fallen in 6 of the last 10 days but is still up by 1.16% over the past 2 weeks. Volume fell on the last day along with the stock, which is actually a good sign as volume should follow the stock. On the last day, the trading volume fell by -208 thousand shares and in total, 790 thousand shares were bought and sold for approximately $69.83 million.

The stock lies the upper part of a very wide and falling trend in the short term, and this may normally pose a very good selling opportunity for the short-term trader as reaction back towards the lower part of the trend can be expected. A break up at the top trend line at $92.23 will firstly indicate a slower falling rate, but may be the first sign of a trend shift. Given the current short-term trend, the stock is expected to fall -7.98% during the next 3 months and, with a 90% probability hold a price between $66.87 and $84.87 at the end of this 3-month period. Do note, that if the stock price manages to stay at current levels or higher, our prediction target will start to change positively over the next few days as the conditions for the current predictions will be broken.

GKOS Signals & Forecast

The Glaukos Corporation stock holds a sell signal from the short-term Moving Average; at the same time, however, there is a buy signal from the long-term average. Since the short-term average is above the long-term average there is a general buy signal in the stock giving a positive forecast for the stock. On further gains, the stock will meet resistance from the short-term Moving Average at approximately $89.28. On a fall, the stock will find some support from the long-term average at approximately $84.11. A break-up through the short-term average will send a buy signal, whereas a breakdown through the long-term average will send a sell signal. 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 Wednesday, November 12, 2025, and so far it has fallen -4.55%. Further fall is indicated until a new bottom pivot has been found. Volume fell together with the price during the last trading day and this reduces the overall risk as volume should follow the price movements.

Support, Risk & Stop-loss for Glaukos Corporation stock

Glaukos Corporation finds support from accumulated volume at $87.80 and this level may hold a buying opportunity as an upwards reaction can be expected when the support is being tested.

This stock may move much during the day (volatility) and with a large prediction interval from the Bollinger Band this stock is considered to be "high risk". During the last day, the stock moved $2.15 between high and low, or 2.43%. For the last week, the stock has had daily average volatility of 4.55%.

Our recommended stop-loss: $83.78 (-5.23%) (This stock has high daily movements and this gives high risk. There is a sell signal from a pivot top found 3 days ago.)

Trading Expectations (GKOS) For The Upcoming Trading Day Of Tuesday 18th

For the upcoming trading day on Tuesday, 18th we expect Glaukos Corporation to open at $89.06, and during the day (based on 14 day Average True Range), to move between $86.10 and $90.70, which gives a possible trading interval of +/-$4.60 (+/-5.34%) up or down from last closing price. If Glaukos Corporation takes out the full calculated possible swing range there will be an estimated 5.34% move between the lowest and the highest trading price during the day.

Since the stock is closer to the support from accumulated volume at $87.80 (0.68%) than the resistance at $89.89 (1.69%), our systems sees the trading risk/reward intra-day as attractive and believe profit can be made before the stock reaches first resistance..
