Lou Basenese pitched MACOM as an AI stock on Fox Business. Insiders sold all year, bought nothing.

The pitch and the price shared a day

Lou Basenese needed 55 seconds on Varney & Company on 1 October↗: MACOM's chips play a critical role in moving the data behind NVIDIA's AI compute, and the company is expanding into space ¹. The stock closed at $301.63, up 5.9% ², one of 40 moves greater than 5% in the past year, on a share price up 72.4% since January ³.

What the pitch costs

Buyers at that price pay 97.0 times trailing earnings against a five-year median of 73.7, and sit 53.8% above the $196.12 fair value one model assigns ². On forward earnings the argument narrows to two numbers: 30.4 times by one count ⁴, 35.9 by another ². Coverage tied the rally partly to a BMO upgrade to Outperform↗; the rating action is dated 18 September, two weeks earlier ³⁵.

Seventy-six trades, one direction

The Form 4 record↗ counts 76 open-market insider trades over the past six months: 76 sales, zero purchases ⁶. Twelve-month insider selling totals $432.1 million, with no buying reported ². Chief executive Stephen Daly sold 19 times for $5.79 million, finance chief John Kober 21 times for $5.16 million, sales chief Donghyun Hwang 32 times for $2.97 million ⁶. In six months, MACOM insiders have voted on their stock 76 times, and every vote was a sale.

The filings, read closely

Daly's 29 May filing, 15,828 shares at $365.75, cut his direct holding 29%, to 38,389 shares; it accounts in full for his $5.79 million six-month tally, so the other 18 sales netted almost nothing ⁷⁶. Kober sold 7,389 shares at $326.08 on 17 August ⁷. Director Peter Chung's 43,268-share sale at $378.20 on 14 May left him 6,781 shares, an 86% cut ⁷. Every one of those prices sits above the 1 October close.

The $432.1 million headline also carries a footnote: roughly $375 million traces to Susan Ocampo, a director and 10% holder whose block sales, including $80.0 million on 24 February alone, run back years; she still held 7.1 million shares after that filing ⁷. None of the filings says whether a sale was prearranged under a trading plan, and intent cannot be read off a Form 4.

The bull case is not vapor

Revenue hit $342.2 million in the July quarter↗, up 35.8% year over year and 18.4% sequentially, with adjusted gross margin at 59.7% ⁸. The 3.2-terabit optical chipset launched 17 September↗ targets AI datacenter interconnects ⁹. Guidance calls for $415 million to $425 million this quarter ⁸. Funds are leaning in: holders rose from 45 to 59 last quarter, short interest is 3.57% of float, and JPMorgan added 2.1 million shares while Invesco cut its stake 41.5% ⁴⁶.

What settles it

The fiscal fourth quarter closes today, 2 October ⁸. The guide asks for a sequential jump of 21% to 24%, bigger than the 18.4% just delivered, and leans on a 3% tax rate and 78.9 million shares, assumptions rather than guarantees ⁸⁴. The growth is on the tape and so is the selling; the next print decides which one the multiple was pricing.
