Samsara falls 7.1% after insider sales coincide with a weak tech day

What happened

Samsara (IOT) fell 7.1% on October 16, 2026, after company insiders reported large stock sales that coincided with a broadly weaker technology sector. Defense World reported that Chief Executive Sanjit Biswas and insider John Bicket sold multiple blocks of company stock between October 13 and October 15, 2026, in transactions at prices ranging from $41.14 to $42.27 per share. The market also weighed a softer day: the S&P 500 fell 1.1% and the technology sector median fell 3.4% on the same day.

How big was the move

The stock closed at $39.57, a decline of 7.1% on the session and down 4.8% over the last five sessions. The session move was 2.0 times a typical daily move for this stock, and trading volume was 1.1 times its 20-day average. The stock was 3.7 percentage points worse than the sector median on the day and has a beta of 1.63, indicating it tends to move more than the market. In the past five years the stock had 41 sessions with a decline of at least 7.1%; twenty trading days later the median result was a decline of 3.3% and 19 of 41 were higher.

The technical picture

Technically, the stock sat 1.2% below its 20-day moving average and 1.0% below its 50-day moving average. The 50-day average is above the 200-day average, a sign of an established uptrend, and the stock has spent 59 consecutive trading days above the 200-day average. It traded 16.6% below its 52-week high. The 14-day Relative Strength Index read 47, inside a neutral range, and 60-day volatility annualized to 57%, lower than 54% of its own readings over five years.

Over shorter horizons the stock fell 1.1% in one month and rose 2.6% over three months; over one year it rose 4.9%, which is 9.9 percentage points behind the S&P 500. Those figures point to modest recent upside but lagging the broader market over the past year.
