TeraWulf drew mixed attention this week as insider selling by CEO Paul B. Prager and Director Walter E. Carter continued to weigh on sentiment, with a Form 144 filing pointing to potential further sales. Wall Street commentary also touched the stock amid broader analyst activity across the data center and AI infrastructure group, while peers Applied Digital and Cipher Digital saw related moves tied to contracted revenue and leasing news in the same sector. Options activity was notable, with 116.37K contracts traded on 25 September against 2.74 million open interest, reflecting elevated speculative positioning.
WULF closed at $15.12, down 3.9%, sitting below both its 50-day average of $16.79 and 200-day average of $18.06, with the shorter average also below the longer one, pointing to a sustained downtrend. The GekkoIndex reads 61.8, placing the stock in the Accumulation zone. Shares trade 34% below the Gekko Fair Value of $22.91.
Over the next 20 trading days, attention turns to earnings scheduled for 9 November, which falls outside this window.

Seasonality data shows the next 20 trading days have averaged a 6.4% return over 5 years, rising in 3 of them. The gap to Gekko Fair Value bears watching alongside continued insider sale disclosures.
