Is Diodes Incorporated stock still a buy after falling -7.88% on Thursday?
(Updated on Jul 16, 2026)

Sell candidate since Jul 01, 2026 Loss -15.29%

The Diodes Incorporated stock price fell by -7.88% on the last day (Thursday, 16th Jul 2026) from $96.92 to $89.28. During the last trading day the stock fluctuated 6.74% from a day low at $88.82 to a day high of $94.80. The price has risen in 6 of the last 10 days but is still down by -15.29% for this period. Volume has increased on the last day by 320 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, 618 thousand shares were bought and sold for approximately $55.21 million.

The stock has broken the very wide and horizontal trend down. Breaks like this are often followed by swift and strong movements, and any correction down to the breakline at approximately $92.47 is considered to be a "second chance" to get out before further fall. It is, however, important to note that false breaks may appear and that the price may move back into the horizontal trend. A break on increasing volume is considered to be more significant and reliable than breaks on low volume.

DIOD Signals & Forecast

There are few to no technical positive signals at the moment. The Diodes Incorporated stock holds sell signals from both short and long-term Moving Averages giving a more negative forecast for the stock. Also, there is a general sell signal from the relation between the two signals where the long-term average is above the short-term average. On corrections up, there will be some resistance from the lines at $93.94 and $104.97. A break-up above any of these levels will issue buy signals. A sell signal was issued from a pivot top point on Monday, June 22, 2026, and so far it has fallen -27.27%. Further fall is indicated until a new bottom pivot has been found. Furthermore, there is currently a sell signal from the 3 month Moving Average Convergence Divergence (MACD). Volume rose on falling prices yesterday. This may be an early warning and the stock should be followed more closely.

Support, Risk & Stop-loss for Diodes Incorporated stock

There is no support from accumulated volume below today's level and given the right condition the stock may perform very badly in the next couple of days.

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 $5.99 between high and low, or 6.74%. For the last week, the stock has had daily average volatility of 5.24%.

Our recommended stop-loss: We hold a negative evaluation for this stock. No stop-loss is set.

Trading Expectations (DIOD) For The Upcoming Trading Day Of Friday 17th

For the upcoming trading day on Friday, 17th we expect Diodes Incorporated to open at $90.97, and during the day (based on 14 day Average True Range), to move between $85.80 and $92.76, which gives a possible trading interval of +/-$6.97 (+/-8.12%) up or down from last closing price. If Diodes Incorporated takes out the full calculated possible swing range there will be an estimated 8.12% move between the lowest and the highest trading price during the day.

With no support below and resistance from accumulated volume @ $101.96, some $12.68 (14.20%) from the current price of $89.28, our system finds the risk reward not very attractive.
