Griffith William J.G. has filed 82 Form 4 transactions across three companies, with a cumulative buy total of $48.98 million against $34 million in sales. That net buying bias is driven almost entirely by open-market purchases in NTSK. On July 8, 2026, he bought $7.2 million worth of NTSK stock, followed by a $2.96 million purchase on July 10 and an $804,546 purchase on July 13. Those three trades, all coded P, account for the bulk of his recent activity and show a clear accumulation pattern in that name.
The selling side is concentrated in TTAN. On June 23, 2026, he sold $3.38 million, $2.52 million, $50,766, and $37,866 in four separate transactions, with a smaller $7,246 sale the prior day. Those sales are the only open-market dispositions in his recent history. The remaining recent filings are coded J, which are not listed in the standard legend and carry zero dollar values. They appear across NTSK, PCOR, and TTAN between August and September 2026, but without a value or a defined code meaning, they do not change the directional picture.
The pattern is straightforward: he bought NTSK aggressively in July and sold TTAN in June. The dollar figures are large enough to be material to his holdings, and the timing shows a clear preference for NTSK over TTAN in recent months. No other transaction types, such as option exercises or tax withholdings, appear in the recent window.
