Director Rose B Andrew purchased 12,380 shares for $503,559.53 at $40.68 blended average; holdings increased 686.6% to 14,183 shares.

Rose B Andrew, as Director, executed 3 separate purchases totaling 12,380 shares for $503,559.53 over two trading days (March 2–3, 2026) at a blended average price of $40.68, expanding her shareholding from 1,803 to 14,183 shares (+686.6%). The timing is notable: the stock currently trades at $40.16, only -3.0% over the past 30 days and +15.2% over 90 days, yet sits -41.4% below its 52-week high of $68.49. Andrew's cross-ticker track record shows mixed results: 3 prior open-market purchases averaged -12.8% returns over 30 days and -11.2% over 90 days, while 4 prior sales achieved a 100% well-timed rate (subsequent declines). The scale of this accumulation—nearly 7x her prior holdings—represents a material commitment to the position, though the pattern of outcomes in her prior buy activity warrants observation.

CFO Gandhi Prithvi bought 15,000 TREX shares at $31.92; holdings doubled to 30,664 shares amid -60.8% decline from 52-week high.

Gandhi Prithvi, SVP and Chief Financial Officer of TREX, executed an open-market purchase of 15,000 shares at $31.92 on 2025-11-14, expanding his holdings by 95.8% from 15,664 to 30,664 shares—a substantial absolute increase reflecting material capital commitment of $478,840.50. The purchase occurs against significant recent price deterioration: the stock is -60.8% from its 52-week high of $79.88 and down -38.3% over the prior 30 days, positioning this transaction at a depressed valuation within recent trading history. Across his cross-ticker open-market history, the insider's prior buy showed a 90-day win rate of 100.00% with an average 90-day return of +15.4%, suggesting a track record of value recognition, though that pattern is not yet proven at TREX specifically. The company's fundamentals remain solid—$285.3M quarterly revenue, $51.8M net income, +5.2% annual revenue growth, and 17.02 P/E—providing a backdrop where the insider's large accumulation in a depressed price window merits investor attention as a signal of perceived value.

SVP Jacob T. Rudolph bought 59 TREX shares at $43.92 amid -33.5% YTD decline; 5 of 5 prior buys at this ticker had positive 90d returns

Rudolph Jacob T. (SVP, CHRO) purchased 59 shares at $43.92 on 2025-10-10, expanding holdings to 27.7K shares. The purchase occurs against a backdrop of significant recent weakness: TREX is down 12.1% over 30 days and 13.2% over 90 days, standing 33.5% below its 52-week high of $79.88. Notably, Rudolph's track record at this ticker is exceptional: all 5 prior open-market buys at TREX demonstrated positive 90-day forward returns, ranging from +0.3% to +37.2%, meaning the stock rallied after each purchase. His cross-ticker buy history similarly shows strong near-term performance (average 30d return +23.4%, average 90d return +10.0% with 100% win rate). The stock currently trades at $53.14, well below the insider's purchase price two weeks prior, suggesting the recent downtrend has accelerated post-transaction.

SVP, CHRO Rudolph Jacob T. bought 66 shares of TREX at $46.22 on 2025-07-03; 5 of 5 prior TREX trades well-timed at 90-day mark.

Rudolph Jacob T., SVP and Chief Human Resources Officer, purchased 66 shares at $46.22 on 2025-07-03, extending his holdings to 27,593 shares. This buy occurs at $11.46 below the current price of $57.68 and 32.8% below the 52-week high of $85.82. The transaction is notable because of a precise timing pattern: all 5 of his prior TREX trades were well-timed at the 90-day mark, including 4 prior buys (ranging from +16.8% to +25.0% 90d returns) and 1 sell (90d return -32.4%, indicating he sold before a decline). His cross-ticker track record shows a 100% win rate on buys with an average 90d return of +9.5%. The current buy price of $46.22, combined with stock appreciation to $57.68 (+24.4% year-to-date) and a robust 90d price change of +14.2%, falls within a favorable entry zone relative to his historical execution. While the $3,050.52 transaction value is modest in absolute terms, the insider's demonstrated timing accuracy on prior trades at this ticker—and his cross-ticker consistency—suggests this purchase warrant close observation through the 90-day window.

TREX SVP/CHRO Jacob buys 53 shares at $49.39; cross-ticker track record shows 4 prior buys with avg 90d return +10.1% vs 1 prior sell with -32.4% avg 90d return

Rudolph Jacob T. (SVP, CHRO) purchased 53 shares of TREX at $49.39 on 2025-04-08, a modest $2,617.67 transaction that increased his holdings from 28,974 to 29,027 shares (+0.2%). His cross-ticker track record across all tickers shows 4 prior buys averaging a 90d return of +10.1% with a 100% win rate, while his single prior sale saw a 90d return of -32.4% and was well-timed at the 100% level. At TREX specifically, his 5 prior trades over the past year have produced mixed outcomes: 4 of 4 measurable trades achieved positive or negative returns consistent with well-timed execution, though the most recent buy on 2025-01-27 is still in early-stage measurement. The current price of $54.94 sits -43.6% from the 52-week high of $97.35, meaning the stock has declined significantly from recent peaks. This purchase arrives as TREX trades within its normalized range and represents a continuation of his consistent buying pattern at this ticker, though the modest share count and dollar value suggest routine portfolio maintenance rather than a material conviction signal.

Rudolph Jacob T. (SVP, CHRO) bought 49 TREX shares at $57.58; prior 4 trades at ticker all well-timed 90d, 100% win rate across buys.

Rudolph Jacob T.'s purchase of 49 shares at $57.58 on 2025-01-27 continues a pattern of precise execution at TREX: all 4 of his prior trades at this ticker achieved their intended outcomes at the 90-day mark, including 3 buys that returned +25.0%, +22.6%, +0.8% and 1 sell that declined -32.4% after execution. His cross-ticker track record reinforces this pattern—3 prior buys averaged 90d return +10.1% with 100% win rate, while his single prior sell achieved -7.1% 30d and -32.4% 90d return (well-timed at 100%). The current price of $72.14 is $14.56 above the transaction price and represents -27.9% from the 52-week high; stock fundamentals show $233.7M quarterly revenue, $40.6M net income, and a P/E of 32.35. This buy extends a consistent track record of well-timed entry points at TREX, though the minimal transaction size (49 shares, $2.8K) limits inference about conviction magnitude.

TREX CHRO Rudolph Jacob T. bought 43 shares at $56.59 on 2024-10-03; stock -33.8% from 52-week high but +8.3% in 30 days.

Rudolph Jacob T., SVP and CHRO, purchased 43 shares of TREX at $56.59 on 2024-10-03, a small absolute addition to holdings of 25.8K shares (+0.2%), while the stock trades at $66.25—33.8% below its 52-week high of $100.10. His track record across all tickers shows 2 prior buys with an average 30-day return of +26.7% and a 100% win rate over 90 days, but at TREX specifically, all 3 prior trades (2 buys, 1 sell) were well-timed at the 90-day mark, with the most recent buy on 2024-07-03 returning +22.6% over 30 days and +7.5% over 90 days. The current 30-day return of +8.3% since this purchase aligns with his favorable timing pattern on this ticker. However, the transaction's modest size relative to holdings and the stock's -6.7% decline over 90 days since the July buy suggests incremental positioning rather than a significant conviction signal; the 52-week price action shows the stock remains well below its recent peak despite near-term recovery momentum.

TREX SVP Rudolph Jacob T. buys 44 shares at $63.00 after May sell; stock down 26.1% in 90 days.

Rudolph Jacob T., SVP and CHRO of TREX, purchased 44 shares at $63.00 on July 3, 2024—a modest transaction valued at $2,772.00 that increased his holdings to 25,790 shares. The timing follows a sale he executed on May 15, 2024, at the same ticker, which registered a -7.1% 30-day return. The stock has experienced significant recent weakness: it is currently trading at $70.96, down 26.1% over the past 90 days and 11.4% over the past 30 days from the transaction date, placing it 29.1% below its 52-week high of $100.10. Across his open-market trading history, his prior buy recorded a +30.8% 30-day return and a +0.8% 90-day return, with a 100% win rate in the 90-day period, though that track record is cross-ticker and the May 15 sale at TREX itself showed poor timing. The fundamental picture presents a mature business with $373.6M quarterly revenue, $89.1M net income, a -1.0% annual revenue growth rate, and a P/E of 30.45, suggesting modest growth expectations are already priced in.
