Reason: Web infrastructure reversed with the rest of software in the week to Friday, October 16: all four names fell, led by $DOCN (down 26.8%, including 14.76% on October 14 after a Barclays downgrade and a UBS target cut, per Weiss Ratings) and $AKAM (down 17.9%), with $NET down 17.91% and $DDOG 15.74%. $DOCN and $AKAM closed under their 200-days, 9.6% and 21.8%, while $NET and $DDOG stay 22.3% and 29.0% above theirs on years of +40.16% and +63.46%: pullbacks in intact trends. A week earlier all four had rallied on Friday with no cause on file.

Price/RSI Table

As of 2026-10-16. Status reads the 200-day trend first and RSI second; Action is a trend-hold lens: a pullback inside an intact trend is a flag to wait for, not an entry, and a name below its 200-day needs a reclaim first.

What Changed Since 2026-10-09

• DOCN: down 26.8% on the week (9.85% on Friday) to RSI 31.0. It fell 14.76% on October 14 after Barclays cut it to Hold and UBS lowered its target to $140, citing AI capacity concerns (Weiss Ratings; October 14 market brief). It is now 9.6% under its 200-day ($109.18), from 25.4% above, 47.37% under its high, though the year is still +129.09% (alpha +113.55 points): a strong long trend now under test.
• AKAM: down 17.9% (4.89% on Friday) to RSI 30.5, 21.8% under its 200-day ($112.26), from 4.6% under, on a +20.35% year with alpha +4.82 points; 46.93% under its high. News was last pulled October 9, so news was not pulled for this move; cause not on file.
• NET: down 17.91% (6.33% on Friday) to RSI 35.9, 22.3% above its 200-day ($242.25) on a +40.16% year (alpha +24.63 points), 19.99% under its high; its regime read moved from uptrend to pullback on Friday with the thesis rated intact. The October 14 market brief had it 0.2% under the floor of its watch zone. News pulled October 16 holds quote pages only. The event file lists the report for November 5 (provider estimate; an October 29 entry was superseded).
• DDOG: down 15.74% (7.19% on Friday) to RSI 41.8 from 73.4, 17.82% under its high from 0.25%; 29.0% above its 200-day ($191.61) on a +63.46% year. News last pulled October 9.
• Group read: the October 12 market brief had web cloud 0 of 9 up on Monday; the cybersecurity scan had all 11 security names down on the week and the cloud-software funds back under the base highs they cleared on October 9. Bloomberg tied the broader week to AI worries pressuring chipmakers (October 16). Roster unchanged since October 9.

Watch

NET's 200-day ($242.25) and DDOG's ($191.61) are the cushions that keep these flags; DOCN ($109.18) and AKAM ($112.26) need a reclaim before they are anything but waiting names. Cloudflare's report is the group's next dated test, listed for November 5 (provider estimate).
