In 2206 alone, insiders have spent billions of dollars buying shares of their own company, with some concentrated in a single large purchase, while others are spread across dozens of consecutive trades over multiple months.
But insiders’ buying and selling habits can point to the direction a company is taking — intense buying periods may signal impending strong financial results, while selling periods could signal troubled waters ahead.
Using SEC filings, Quiver Quantitative parsed insider trading data to create a dashboard — tracking what insiders are doing with a company’s shares. Here’s what the dashboard has revealed about insider purchasing in 2026:
What companies have seen insiders spend big on shares?

Two insider purchases worth an estimated $628 million
SMFG, one of the top Japanese financial groups, made two major purchases in JEF shares. The trades came after the two companies announced a joint venture — SMBC Nikko Jefferies Securities — set to launch in January 2027.
As part of this, SMFG now holds around a 20% stake in JEF, while maintaining 5% voting power.
Jack Jiang Huang — CEO of 51Talk Online Education Group (COE)

Mitsui Sumitomo Insurance — 10% owner of W.R. Berkeley (WRB)
27 purchases since January 2026 totaling nearly $160 million
Every insider purchase made in 2026 of W.R. Berkeley — the Fortune 500 insurance holding company — shares came from major global property and casualty insurance company Mitsui Sumitomo.
Mitsui Sumitomo invested $3.8 billion in WRB, acquiring a 15% ownership stake in the Connecticut-based insurance company. Mitsui Sumitomo’s stake in the company resulted entirely from open-market or secondary purchases, meaning they purchased their shares through public stock exchanges or from pre-existing holders — also signaling insider confidence in the company.
